Tagged: ssd, sata 3, pny, 3d nand
PNY has added a new solid-state drive to its CS900 lineup doubling the capacity to 960GB. The SATA-based SSD is a 2.5" 7mm affair suitable for use in laptops and SFF systems as well as a budget option for desktops.
The CS900 960GB SSD uses 3D TLC NAND flash and offers ECC, end-to-end data protection, secure erase, and power saving features to protect data and battery life in mobile devices. Unfortunately, information on the controller and NAND flash manufacturer is not readily available though I suspect it uses a Phison controller like PNY's other drives.
The 960GB capacity model is rated for sequential reads of 535 MB/s and sequential writes of 515 MB/s. PNY rates the drive at 2 million hours MTBF and they cover it with a 3-year warranty.
We may have to wait for reviews (we know how Allyn loves to tear apart drives!) for more information on this drive especially where random read/write and latency percentile performance are concerned. The good news is that if the performance is there the budget price seems right with an MSRP of $249.99 and an Amazon sale price of $229.99 (just under 24 cents/GB) at time of writing. Not bad for nearly a terabyte of solid state storage (though if you don't need that much space you can alternatively find PCI-E based M.2 SSDs in this price range).

The price of the 480GB 900P is somewhat prohibitive but the small size of the 32GB gumstick also causes one pause; hence the 800P family with a 58GB and a 118GB model. They bear price tags of $130 and $200, as you may remember from Al's review. The Tech Report also had a chance to test these two Optane sticks out, with some tests not covered in our review, such as their own real world copying benchmark. If you are looking for a second opinion, drop by and take a look.
"Intel's duo of Optane SSD 800P drives promises the same blend of impressively-low latency and performance consistency as its larger Optane devices at a price more builders can afford. We ran these drives through our storage-testing gauntlet to see whether they can make a name for themselves as primary storage."

Western Digital launched a few new NVMe SSDs at Mobile World Congress today:
To the left we have the WD PC SN720, a PCIe 3.0 x4 NVMe SSD boasting speeds of up to 3.4GB/s and IOPS up to 500k. Available capacities are 1TB, 512GB, and 256GB. To the right we have the WD PC SN520, a more power efficient variant running on half of the PCIe lanes, and with specs coming in at roughly half of its faster brother. Capacities are also cut in half, with the range dropping to 512GB, 256GB, and 128GB. Interestingly, all capacities are available in three M.2 form factors (2280, 2242, and 2230).
We don't have a specific part number for the controller, but WD told us they are manufactured on a 28nm process, employ 8 NAND channels, and use DDR4 RAM (not DRAMless). The controller is optimized for interfacing with WD (/Toshiba) BiCS NAND flash, meaning these SSDs should prove to be a well integrated solution.
Press blast from WD appears after the break.

Tagged: UFS, Samsung, eUFS, embedded, automotive, adas, 256GB
Samsung announced yesterday that it has begun mass production of 256 GB eUFS (Embedded Universal Flash Storage) flash storage for embedded automotive applications. Doubling the capacity of the 128GB eUFS flash it announced last fall, the new embedded flash conforms to the newer JEDEC eUFS 3.0 standard including the new temperature monitoring and thermal throttling safety features which Samsung reportedly had a hand in developing. The new embedded storage is aimed at smart vehicles for use in driver assistance features (ADAS), infotainment systems, and next-generation dashboards.
The new eUFS 3.0 compliant flash is notable for featuring increased temperature ranges of between -40°C and 105°C for both operational and idle/power saving modes which makes it much better suited for use in vehicles where temperature extremes can be reach both from extreme weather and engine heat. Samsung compares its eUFS flash with traditional eMMC 5.1 storage which has a temperature range of only -25°C to 85°C when in use and -40°C to 85°C when in power saving mode.
Samsung’s eUFS can hit sequential read speeds of up to 850 MB/s and random read performance of up to 45,000 IOPS. Samsung did not specify write performance numbers but based on its other eUFS flash sequential and random writes should be in the neighborhood of 250 MB/s and 40,000 IOPS respectively. According to Samsung in its press material for 512GB eUFS for smartphones, the 256GB eUFS for the automotive market is composed of 8 stacks of 48-layer 256Gb V-NAND and a controller all packaged together to hit the 256GB storage capacity. Samsung has included a temperature sensor in the flash along with the ability for the controller to notify the host AP (application processor) at any pre-set temperature thresholds to enable the AP to downclock to lower power and heat to acceptable levels. The temperature monitoring hardware is intended to help protect the heat sensitive NAND flash from extreme temperatures to improve data reliability and longevity. The eUFS flash also features a “data refresh” feature that improves long term performance by relocating older data to less-often used cells. Embedded Universal Flash Storage (eUFS) is interesting compared to eMMC for more than temperatures though as it uses a dual channel LVDS serial interface that allows it to operate in full duplex mode rather than the half duplex mode of eMMC with its x8 parallel interface. This means that eUFS can be read and written to simultaneously and with the addition of command queueing, the controller is able to efficiently execute and prioritize read/write operations and perform error correction without involving the host processor and software.
I am looking forward to the advancements in eUFS storage and its use in more performant mobile devices and vehicles, especially on the low end in tablets and notebooks where eMMC is currently popular.

SK Hynix has revealed its new enterprise solid state drives based on 72-layer 512 Gb 3D TLC NAND flash dies paired with the company's own in-house controller and firmware. The SK Hynix eSSDs are available in a traditional SAS/SATA interfacing product with capacities up to 4TB and a PCI-E variant that comes in 'above 1TB." Both drive types are reportedly being sampled to datacenter customers in the US.
SK Hynix has managed to double the capacity and improve the read latency of its new 512 Gb 72-layer NAND flash over its previous 256 Gb 72-layer flash which debuted last year. The eSSD product reportedly hits sequential read and write speeds of 560 MB/s and 515 MB/s respectively. Interestingly, while random read IOPS hit 98,000, random write performance is significantly lower at 32,000 IOPS. SK Hynix did not go into details, but I suspect this has to do with the tuning they did to improve read latency and the nature of the 72-layer stacked TLC flash.
Moving up to the PCI-E interfacing eSSD, customers can expect greater than 1TB capacities (SK Hynix did not specify the maximum capacity they will offer) with sequential reads hitting up to 2,700 MB/s and sequential writes hitting 1,100 MB/s. The random performance is similar to the above eSSD with write performance being much lower than read performance at 230K read IOPS and 35K write IOPS maximum. The greatly limited write performance may be the result of the drive not having enough flash channels or the flash itself not being fast enough at writes which was a tradeoff SK Hynix had to make to hit the capacity targets with larger capacity 512 Gb (64 GB) dies.
Unfortunately, SK Hynix has not yet provided further details on its new eSSDs or the 3D-V4 TLC NAND it is using in the new drives. SK Hynix continuing to push into the enterprise storage market with its own SSDs is an interesting play that should encourage them push for advancements and production efficiencies to advance NAND flash technology.

Tagged: toshiba, ssd, SM2258, silicon motion, plextor, BiCS, 3d nand
Plextor is introducing a new SATA SSD option with its 2.5” M8VC and M.2 M8VG solid state drives. The M8V series pairs a Silicon Motion SM2258 controller with Toshiba’s 64-layer 3D TLC NAND (BICS flash) to deliver budget SSDs in 128 GB, 256 GB, and 512 GB capacities. Plextor is using its own Plex Nitro firmware and includes SLC cache, system RAM cache support, Plex Compressor compression, 128-bit ECC and LDPC error correction, and hardware AES encryption. Plextor warranties its M8V series SSDs for three years.
Plextor’s new drives are limited by the SATA 6 Gbps interface and max out at 560 MB/s sequential reads. Sequential writes top out at 400 MB/s for the 128 GB model, 510 MB/s for the 256 GB model, and 520 MB/s for the 512 GB drive. Similarly, 4K random reads and 4K random writes scale up as you add more flash which is shown in the table below. The top-end 512 GB drive hits 82K 4K random read IOPS and 81K 4K random write IOPS. The 256 GB solid state drives are only slightly slower at 81K and 80K respectively. The 128 GB M8V SSDs do not appear to have enough flash channels to keep up with the larger capacity drives though as their performance maxes out at 60K random reads and 70K random writes.
|Plextor M8V Series||128 GB||256 GB||512 GB|
|Sequential Reads||560 MB/s||560 MB/s||560 MB/s|
|Sequential Writes||400 MB/s||510 MB/s||520 MB/s|
|4K Random Read IOPS||60K||81K||82K|
|4K Random Write IOPS||70K||80K||81K|
|Endurance||70 TBW||140 TBW||280 TBW|
|MTBF (hours)||1.5 Million||1.5 Million||1.5 Million|
Plextor rates the M8V series at 0.5 DWPD (drive writes per day) and write endurance of 70 TB for the 128 GB, 140 TB for the 256 GB, and 280 TB for the 512 GB model. Plextor rates them at 1.5 million hours MTBF. These numbers aren’t too bad considering this is TLC flash and they are likely to get more life than the ratings (it’s just not guaranteed).
The SM2258 controller appears to be fairly well established and has also been used by Adata, Mushkin, and others for their budget solid state drives. Plextor did not announced pricing or availability and in searching around online I was not able to find them for sale yet. Its previous S2C series (M7V replacement) SATA drives came in at just under 26 cents/gigabyte using the same SMI 2258 controller but with SK Hynix 16nm planar TLC flash though so I would expect the M8V to come in close to that if not better.
I just wish we could get a SATA 4 standard already to at least get consumer systems up to the 12 Gbps enterprise-oriented SAS can hit. While RAM and GPU shopping may make your wallet cry more than a Steam sale, at least it is a good time to be shopping for storage. What do you think about the influx of budget SSDs? Have you upgraded your family’s PCs to the magical performance of solid state storage yet?

External storage does not have to be slow, as the OWC Mercury Helios 3 PCIe Thunderbolt 3 external drive demonstrates. The TB3 connection is capable of up to 40Gbps, assuming you have the proper connection, which will keep a drive such as the the Kingston DC1000 NVMe SSD very busy. In The SSD Reviews testing, they saw the data transfer cap out at 2.8GB/s read and between 2.5-2.7GB/s write, which makes this perfect for HD video or for manipulating large media files. The enclosure will set you back about $200, the cost of the PCIe SSD you put inside it is a choice for you to make.

Seagate Technology has announced its quarterly earnings for the second quarter of fiscal year 2018 (the quarter ending 12/29/2017). The Cupertino-based company has reported quarterly revenue of $2.9 billion, net income of $159 million, and diluted EPS of 55 cents. On a Non-GAAP reporting basis, Seagate saw Q2 FY2018 net income of $431 million and earnings per share of $1.48.
Seagate's revenue remained flat year-over-year, but increased 11.5% versus the previous quarter. Net income decreased 12% QOQ and 46% YoY using GAAP accounting methods, but on a non-GAAP basis Seagate reports a 54% increase versus the previous quarter and 4.6% increase versus the same quarter last year so it's not all bad news. The company is also managed to amass quite a bit of cash including $850 million from operations and $773 of free cash flow.
|Q2 FY2018||Q1 FY2018||Q2 FY2017||QOQ||YoY|

Seagate manufactures both mechanical hard drives and solid state drives, and while the company cranks out many internal and external drives for consumers, the company is very much focused on the enterprise market, especially where its solid state storage is concerned. Seagate states in its press release that it is heavily focused on cloud storage with its 60TB 3.5" SAS drive and NVMe add-in-card (which it demonstrated at FMS 2016). The company has partnered with Facebook to build its 1U Lightning storage solution (up to 120TB of flash storage using 60 2TB M.2 NVMe drives) and continues to target the enterprise and exascale/HPC markets with their absolutely massive and ever-growing data demands for big data analytics of financial and user data, uploaded and user-generated media, cloud backup, and research/simulation data for supercomputers. Further, the company continues to push mechanical enterprise storage to ever higher capacities with Barracuda Pro and also has its Ironwolf NAS and sequential-optimized Skyhawk drives for surveillance systems. On the flash storage front, Seagate has its Nytro M.2 NVMe and Nytro SAS SSDs.

I am interested to see where Seagate (STX) will go with its flash storage (Will they ever bring it to the consumer market in a big way? They do have a few products, but their focus seems to be mostly on enterprise.) and if they will manage to match or surpass Western Digital and Toshiba this year in the enterprise HDD capacity war. Currently, the company's Barracuda, IronWolf, and Exos drives top out at 12TB including the second generation Helium-sealed versions.

Tagged: z-ssd, Z-NAND, Samsung, HPC, enterprise, ai
Samsung will be introducing a new high performance solid state drive using new Z-NAND flash at ISSCC next month. The new Samsung SZ985 Z-SSD is aimed squarely at the high-performance computing (HPC) market for big data number crunching, supercomputing, AI research, and IoT application development. The new drive will come in two capacities at 800GB and 240GB and combines low latency Z-NAND flash with 1.5GB LPDDR4 DRAM cache and an unspecified "high performance" Samsung controller.
The Z-NAND drive is interesting because it represents an extremely fast storage solution that offers up to 10-times cell read performance and 5-times less write latency than 3-bit V-NAND based drives such as Samsung's own PM963 NVMe SSD. The Z-NAND technology represents a middle ground (though closer to Optane than not) between NAND and X Point flash memory without the expense and complexity of 3D XPoint (at least, in theory). The single port 4-lane drive (PCI-E x4) reportedly is able to hit random read performance of 750,000 IOPS and random write performance of 170,000 IOPS. The drive is able to do this with very little latency at around 16µs (microseconds). To put that in perspective, a traditional NVMe SSD can exhibit write latencies of around 90+ microseconds while Optane sits at around half the latency of Z-NAND (~8-10µs). You can find a comparison chart of latency percentiles of various storage technologies here. While the press release did not go into transfer speeds or read latencies, Samsung talked about that late last year when it revealed the drive's existence. The SZ985 Z-SSD maxes out its x4 interface at 3.2 GB/s for both sequential reads and sequential writes. Further, read latencies are rated at between 12µs and 20µs. At the time Allyn noted that the 30 drive writes per day (DWPD) matched that of Intel's P4800X and stated that it was an impressive feat considering Samsung is essentially running its V-NAND flash in a different mode with Z-NAND. Looking at the specs, the Samsung SZ985 Z-SSD has the same 2 million hours MTBF but is actually rated higher for endurance at 42 Petabytes over five years (versus 41 PB). Both drives appear to offer the same 5-year warranty though we may have to wait for the ISSCC announcement for confirmation on that.
It appears that the SZ-985 offers a bit more capacity, higher random read IOPS, and better sequential performance but with slightly more latency and lower random write IOPS than the 3D XPoint based Intel Optane P4800X drive.
In all Samsung has an interesting drive and if they can price it right I can see them selling a ton of these drives to the enterprise market for big data analytics tasks as well as a high-speed drive for researchers. I am looking forward to more information being released about the Z-SSD and its Z-NAND flash technology at the ISSCC (International Solid-State Circuits Conference) in mid-February.

Intel have released a new M.2 SSD line which will come in 128GB, 256GB and 512GB with prices of $74, $109 and $199 respectively. This is a far cry from falling under Ryan's Law but are lower than other NVMe drives. The Tech Report believes it is using the Silicon Motion SM2262 controller though Intel is being cagey about confirmation, with 64-layer TLC flash for storage. The overall performance was mixed, for reads this drive is one of the best TR have tested however the write speeds are barely faster than a SATA drive; at this price point that should not scare you off unless you plan on doing a lot of writes.
"Intel is shaking up the mainstream SSD market by releasing a new NVMe drive at what it calls near-SATA prices. We run the drive through our storage-testing gauntlet to see whether the SSD 760p 512 GB and its 64-layer NAND turn out to be a game-changer."

In addition to the PCI-E based solid state drives it showed off at CES, Mushkin is adding two new SATA-based SSDs to its Triactor series. The new Triactor 3DL and Triactor 3DX are M.2 and 2.5" form factor SSDs respectively that are available in 120 GB, 250 GB, 500 GB, and 1 TB capacities and utilize 3D TLC NAND flash memory and SMI controllers. Both drives come with M.E.D.S. wear leveling and data protection algorithms and three-year warranties.
The Triactor 3DL is a M.2 2280 form factor SSD that uses a SMI SM2258XT controller with a SATA 3.1 6 Gbps interface. The SM2258XT is a four-channel controller that lacks a DRAM cache. The Triactor 3DL is rated at up to 550 MB/s sequential reads, 505 MB/s sequential writes, 73,000 random 4k read IOPS and 80,000 random 4k write IOPS. Its data protection features include LDPC ECC and algorithms for data shaping, StaticDataRefresh, and wear leveling. While not as impressive as its NVMe M.2 counterparts, it should be a good bit cheaper and compatible with more PCs especially as an upgrade path for older notebooks.
On the other hand, the Triactor 3DX is a more traditional SATA drive that comes in a 2.5" form factor (7mm thick). In this case the 3D TLC NAND flash is paired with a SMI SM2258 controller which is similar to the one above except that it can utilize a DRAM cache and supports AES encryption. The Triactor 3DX is rated at 565 MB/s sequential reads, 530 MB/s sequential writes, 100,000 random 4k read IOPs, and 91,000 random 4k write IOPS. It seems that the cache is helping performance a bit, and the drive is starting to bump up against the real-world limits of the SATA 6 Gbps interface. Since it is of the thinner 7mm type, it will be compatible with most notebooks and desktops.
The new Triactor drives are cheaper options that come in M.2 as well as traditional SATA drives. Mushkin is not talking pricing or availability just yet.

Here is Crucial's product tour video for the MX500:
We previously tested the 1TB MX500, and Crucial passed along a 500GB model that I was able to spot check to ensure there was no performance fall-off at the smaller capacities of this line:
Looks good so far, and nearly identical to the 1TB capacity across our entire test suite. We did also speak with Crucial reps (Jon and Jon) about the TRIM speed issues noted in our previous review. They are looking into replicating our testing and may be pushing out a firmware to help improve this metric moving forward.
We also saw some sweet looking new RGB Ballistix memory, due out shortly. More to follow there! Crucial's MX500 CES announcement appears after the break.

Mushkin is on site at CES where it is launching a slew of new products. On the storage front, Mushkin is showing off three new M.2 2280 form factor NVMe solid state drives aimed at various price points. The Pilot, Pilot-E, and Helix-L M.2 drives all use Silicon Motion controllers and 3D TLC NAND flash memory. Mushkin further advertises them with a three-year warranty and the company's MEDS Reliability Suite which includes technology to enable end-to-end data path protection, LDPC ECC, and global wear leveling algorithms to ensure data integrity and longevity.
At the top end of performance is the Pilot-E M.2 SSD based on SM2262EN controller which offers up eight channels for connecting all the 3D NAND. This 250 GB to 2 TB drive is able to achieve extremely speedy 3.5 GB/s sequential reads and 3.0 GB/s sequential writes along with 370K read IOPS and 300K write IOPS. Essentially, the Pilot-E M.2 should be able to easily max out the PCI-E x4 connection with the right workloads.
Stepping down a bit, the Pilot drive uses an eight channel SM2262 controller. This drive gets close to the Pilot-E in reads, but has much lower sequential write performance. Capacities for this SSD range from 120 GB to 2 TB. Specifically, the Pilot SSD is rated at 3.2 GB/s sequential reads, 1.9 GB/s sequential writes, 370K random read IOPS, and 300K random write IOPS. This drive should be cheaper than the Pilot-E and will be aimed at the consumer space where reads are more important than writes.
Finally, Mushkin's Helix-L is a lower cost SSD that uses a DRAM-less design to reduce cost as well as a cheaper four channel SM2263XT controller. Capacities range from 120 GB to 1TB. This SSD supports Host Memory Buffer architecture which allows it to use system memory as a cache to improve performance. The Helix-L is rated at 2.4 GB/s sequential reads, 1.7 GB/s sequential writes, 280K random read IOPS (140K without HMB) and 250K random write IOPS.
Mushkin has not yet revealed pricing or availability on its new NVMe 1.3 drives. You can read more about the Silicon Motion controllers used here.

Intel broke news just now that they will be launching a larger version of their 16/32GB Optane Memory modules. The new 800P looks very much the same as its little brother but is designed to operate as a sole boot SSD. Mobile applications are also possible now as the 800P includes power management features that the Optane Memory modules lacked (as they were not intended for mobile).
We are under embargo as far as performance goes, but from what we know about how Optane parts scale, it's a safe bet that performance will be very close to what we've seen out of the Optane Memory parts. Warranty will be 5 years with an endurance of ~200GB per day. No word on cost at this time. Overall these though fit nicely between Optane Memory (16/32GB) and the 900P (280/480+GB) capacity points.
The elephant in the room is the capacity. While these can store more than the 16/32GB variants, 60/120GB may not be enough for most users out there. Fortunately, devices like these are great in Zx70 RAID or even VROC configurations!

Dell has just announced a pair of external SSDs. The Dell SDI T0500 will have a 500 GB capacity. The Dell SDI T1000 will, as the name suggests, doubles that to 1 TB. Both external SSDs connect via Thunderbolt 3. Because it’s using this connector, we can expect it to be fast but not mass-market. I am guessing that Dell intends this product to be purchased with one of their Thunderbolt 3 laptops, and probably with a specific type of user in mind. That is just my speculation, though.
Unfortunately, we don’t have much else to go on. No price, availability, read or write speeds, IO throughput, or anything else has been published.

Memory firm Patriot announced a new Thunderbolt 3 portable SSD at CES this week. The Patriot EVLVR ("evolver") is based on Phison E8 PCIe controller and advertises speeds of up to 1500MB/s in sequential reads and 1000MB/s in sequential writes.
The drive connects to PCs and Macs via a single detachable Thunderbolt 3 cable and is bus-powered, although there is no second Thunderbolt port for passthrough capability.
The Patriot EVLVR launches in March and will be available in 256GB ($199.99), 512GB ($289.99), and 1TB ($489.99) capacities.

Elgato is launching a smaller Thunderbolt 3 dock aptly named the Thunderbolt 3 Mini Dock to its family of docks (how many times can I use dock in one sentence?). The portable dock comes with a tail Thunderbolt 3 cable that is permanently attached and stows away into a groove on the bottom of the dock when not in use.
Using the single 40 Gbps connection provided by Thunderbolt 3, the Mini Dock offers up display outputs, USB 3.1, and network ports including:
- DisplayPort 1.2 (4k60)
- HDMI 2.0 (4k60 and HDCP 2.2)
- RJ45 (Gigabit Ethernet)
- USB 3.1 Gen 1 (5Gbps UASP and 0.9A of power).
Users will need a newer laptop or desktop with Thunderbolt running Mac OS Sierra 10.12 or Window 10 operating systems or newer. The compact dock will be available in the sping with as yet unanounced pricing. It should be cheaper than Elgatos larger docks (currently their Thunderbolt 3 Dock is $291) though since it is not powered and offers fewer ports.
As notebooks continue to get thinner, these docks (along with ones based on USB Type-C) are going to become more useful in getting the most out of our faster mobile hardware.
Stay tuned to PC Perspective for more CES news as it develops!

Toshiba announced a couple of new additions to their SSD lineup. First up is the RC100:
This is a DRAMless design intended to target budget builds - something much needed in the current (pricey) SSD landscape. Just because there is no DRAM present in the design does not mean that the RC100 can't perform well. Toshiba has implemented the Host memory Buffer (HMB) feature, which allows the NVMe driver to share a small (38MB) portion of host memory via the same PCIe 3.0 x2 link used to transfer user data. This memory portion effectively caches a portion of the FTL, which should bring the random performance of smaller sections of the SSD up to what you would expect to see from a higher performance product. Specs are as follows:
- Capacities: 120/240/480GB
- PCIe 3.0 x2
- Random read/write: 160/120k IOPS
- Sequential read/write: 1620/1130 MB/s
- Warranty: 3 years
Up next is the XS700, Toshiba's first portable SSD:
- 240GB only
- USB 3.1 Gen2 (type-c connector on device)
- Ships with type-c to type-a cable
The XS700 is the first portable SSD I've seen out of Toshiba. It was just a matter of time here as just about every other major SSD maker has offered a similar product.
We don't have pricing yet, but these should shape up to be highly price-competitive products offering decent performance. Both models will be coming later this year.
Press blast after the break.

Tagged: RS4, RS3, patch, meltdown, KB4056892, cpu, 960 EVO, 900P, 850 EVO
While the Meltdown announcements and patches were in full swing, I was busily testing a round of storage devices to evaluate the potential negative impact of the Meltdown patch. Much of the testing we've seen has come in the form of Linux benchmarks, and today we saw a few come out on the Windows side of things. Most of the published data to date shows a ~20% performance hit to small random accesses, but I've noted that the majority of reviewers seem to be focusing on the Samsung 950/960 series SSDs. Sure these are popular devices, but when evaluating changes to a storage subsystem, it's unwise to just stick with a single type of product.
Test conditions were as follows:
- ASUS Prime Z270-A + 7700K
- C-States disabled, no overclock.
- ASUS MCE disabled, all other clock settings = AUTO.
- Intel Optane 900P 480GB (Intel NVMe driver)
- Samsung 960 EVO 500GB (Samsung NVMe driver)
- Samsung 850 EVO 500GB (Intel RST driver)
- NTFS partition.
- 16GB test file. Sequential conditioning.
- Remainder of SSD sequentially filled to capacity.
The first results come from a clean Windows Redstone 3 install compared to a clean Windows 10 Redstone 4 (build 17063), which is a fast ring build including the Meltdown patch:
The 960 EVO comes in at that same 20% drop seen elsewhere, but check out the 850 EVO's nearly 10% *increase* in performance. The 900P pushes this further, showing an over 15% *increase*. You would figure that a patch that adds latency to API calls would have a noticeable impact on a storage device offering extremely low latencies, but that did not end up being the case in practice.
Since the 960 EVO looked like an outlier here, I also re-tested it using the Microsoft Inbox NVMe driver, as well as by connecting it via the chipset (which uses the Intel RST driver). A similar drop in performance was seen in all configurations.
The second set of results was obtained later, taking our clean RS3 install and updating it to current, which at the time included the Microsoft roll-up 01-2018 package (KB4056892):
Note that the results are similar, though Optane did not see as much of a boost here. It is likely that some specific optimizations have been included in RS4 that are more beneficial to lower latency storage devices.
As a final data point, here's what our tests look like with software polling implemented:
The above test results are using an application method that effectively bypasses the typical interrupt requests associated with file transfers. Note that the differences are significantly reduced once IRQs are removed from the picture. Also note that kernel API calls are still taking place here.
Well there you have it. Some gain and some lose. Given that a far lower latency device (900P) sees zero performance hit (actually gaining speed), I suspect that whatever penalty associated with Meltdown could be easily optimized out via updates to the Windows Inbox and Samsung NVMe drivers.
