It appears Samsung were paying attention to the many reviews pointing out that the price premium was getting harder to justify in the face of competing drives closing in on performance because along with purchase availability came some nice price cuts:

Old pricing:

  • 970 PRO
    • 512GB - $330 ($0.64/GB)
    • 1TB      - $630 ($0.62/GB)
  • 970 EVO
    • 250GB - $120 ($0.48/GB)
    • 500GB - $230 ($0.46/GB)
    • 1TB      - $450 ($0.45/GB)
    • 2TB      - $850 ($0.43/GB)

New pricing (MSRP):

  • 970 PRO
    • 512GB - $250 ($0.49/GB)
    • 1TB      - $500 ($0.49/GB)
  • 970 EVO
    • 250GB - $110 ($0.44/GB)
    • 500GB - $200 ($0.40/GB) (Amazon)
    • 1TB      - $400 ($0.40/GB) (Amazon)
    • 2TB      - $800 ($0.40/GB)

These are not sale prices - these are the revised suggested retail prices (MSRP) from Samsung! It looks like Newegg and Amazon are now populating their listings with 970 SSDs at the revised pricing.

Someone order a round of Samsung NVMe?

Introduction, Specifications and Packaging

Introduction:

Over the past couple of days, we saw some rumors and e-tailer appearances of the Intel SSD 905P. Essentially an incremental upgrade to the 900P, with a few notable differences. Specs see a slight bump across the board, as do capacities, but the most striking difference is Intel’s apparent choice to move forward with the blue-LED enabled design seen in a press deck slide that began circulating last year:

intel-optane-ssd-900p.jpg

That upper right design seemed pretty cool at the time, and I never thought we would see it materialize, but less than 24 hours ago this arrived at the office:

Note: The color is user adjustable - we just don't have the software for it yet.

*edit* colors are configurable via command line, using the most recent SSD toolbox app. The possible colors are limited (literally red/green/blue/off - that's it), but I've confirmed that the setting does persist after reboot / power cycling / changing systems. This is a welcome change over other RGB-enabled components that require software to always be installed to control (or even turn off) lighting. Here's a look at the other two colors:

Introduction, Specifications and Packaging

Introduction:

We have been overdue for a Samsung NVMe SSD refresh, and with the launch of their 860 PRO and EVO back in January, folks have been itching for the 970's to come out. The 950 and 960 (PRO) lines were separated by about a year, but we are going on 18 months since the most recent 960 EVO launch. Samsung could afford to wait a bit longer since the 960 line already offered outstanding performance that remained unmatched at the top of our performance charts for a very long time. Recently, drives like the WD Black have started catching up, so it is naturally time for Samsung to keep the competition on their toes:

180423-175345.jpg

Today we will look at most of the Samsung 970 PRO and EVO lineup. We have a bit of a capacity spread for the EVO, and a single PRO. Samples are hard to come by so far since Samsung opted to launch both lines at the same time, but we tried to get the more common capacities represented. EVO 2TB and PRO 1TB data will have to come at a later date.

Specifications:

specs-EVO.png

Specs come in at just slightly higher than the 960 lines, with some welcome additions like OPAL and encrypted drive (IEEE1667) support, the latter being suggested but never making it into the 960 products. Another welcome addition is that the 970 EVO now carries a 5-year warranty (up from 3).

specs-EVO-2.png

The 970 EVO includes 'Intelligent TurboWrite', which was introduced with the 960 line. This setup maintains a static SLC area and an additional 'Intelligent' cache that exists if sufficient free space is available in the TLC area.

Packaging:

Packaging is in line with the previous 960 series parts. Nice packaging. If it ain't broke, don't fix it.

Friday storage roundup

Tagged: round up, ssd, hdd, external drive, NAS

The SSD market is somewhat daunting to a newcomer, not just the various interfaces and technology but also the huge selection of models from the various suppliers.  HDDs and NAS devices are a little less so, but there is still a large variety to choose from. TechSpot offer their advice, with a round up of what they consider the best of the best in six categories of storage devices.  Quickly take a look to see if you agree, as it is all likely to change again very soon.

"With solid state drives now fully mainstream and hard drives being more affordable than ever, there is a broad a mix of high-performance and high-capacity options to choose from in a range of form factors. Fortunately for you, we have spent dozens of hours testing storage devices, so we have a pretty clear idea about what devices are worth buying."

NVMe RAID and StoreMI

With Ken testing all of the new AMD X470 goodness that we had floating around the office here at PCPer, I snuck in some quick storage testing to get a look at just how the new platform handled a typical power user NVMe RAID configuration. We will be testing a few different platform configurations:

  • ASUS Z270 w/ 7700K
    • 1x SSD behind chipset (PCH)
    • 2x SSD (RAID-0) behind chipset (PCH)
    • 1x SSD directly connected to CPU
  • AMD X470 w/ 2600X
    • 1x SSD via RAIDXpert bottom driver
    • 2x SSD (RAID-0) via RAIDXpert
    • 1x SSD via MS InBox NVMe driver

For the AMD system we tested, all M.2 ports were direct connected to the CPU. This should be the case for most systems since the AMD chipset has only a PCIe 2.0 x4 link which would cut most NVMe SSD bandwidth in half if passed through it. The difference on AMD is that installing the RAIDXpert software also installs a 'bottom driver' which replaces the Windows NVMe driver, while Intel's RST platform handles this process more in the chipset hardware (but is limited to PCIe 3.0 x4 DMI bandwidth). Now onto the results:

Random Read IOPS

random.png

For random IO, we see expected scaling from AMD, but do note that IOPS comes in ~40% lower than the same configuration on Intel's platform. This is critical as much of the IO seen in general use is random reads at lower queue depths. We'd like to see AMD doing better here, especially in the case where a single SSD was operating without the interference of the RAIDXpert driver, which was better, but still not able to match Intel.

Random Read Latency

latency.png

This latency chart should better explain the IOPS performance seen above. Note that the across the board latency increases by ~10us on the X470 platform, followed by another ~20us when switching to the RAIDXpert driver. That combined ~30us is 50% of the 60us QD1 latency seen the Z270 platform (regardless of configuration).

Sequential Read

sequential.png

Ok, now we see the AMD platform stretch its legs a bit. Since Intel NVMe RAID is bottlenecked by its DMI link while AMD has all NVMe SSDs directly connected to the CPU, AMD is able to trounce Intel on sequentials, but there is a catch. Note the solid red line, which means no RAIDXpert software. That line tracks as it should, leveling off horizontally at a maximum for that SSD. Now look at the two dashed red lines and note how they fall off at ~QD8/16. It appears the RAIDXpert driver is interfering and limiting the ultimate throughput possible. This was even the case for a single SSD passing through the RAIDXpert bottom driver (configured as a JBOD volume).

StoreMI

2018-04-19-08-49-39.png

AMD has also launched their answer to Intel RST caching. StoreMI is actually a more flexible solution that offers some unique advantages over Intel. Instead of copying a section of HDD data to the SSD cache, StoreMI combines the total available storage space of both the HDD and SSD, and is able to seamlessly shuffle the more active data blocks to the SSD. StoreMI also offers more cache capacity than Intel - up to 512GB SSD caches are possible (60GB limit on Intel). Lastly, the user can opt to donate 2GB of RAM as an additional caching layer.

2018-04-19-08-49-55.png

AMD claims the typical speedups that one would expect with an SSD caching a much slower HDD. We have done some testing with StoreMI and can confirm the above slide's claims. Actively used applications and games end up running at close to SSD speeds (after the first execution, which comes from the HDD). StoreMI is not yet in a final state, but that is expected within the next week or two. We will revisit that topic with hard data once we have the final shipping product on-hand.

Western Digital Launches Ultrastar DC HC530 - TDMR 14TB HDD

Tagged: wdc, WD, ultrastar, sata, SAS, HelioSeal, hdd, DC HC530, 14tb

Following up on the prior release of a 14TB SMR (shingled magnetic recording) HDD, WD has launched a PMR (parallel magnetic recording)version of the same - the Ultrastar DC HC530:

UltrastarDC-HC530.jpg

While the new model does not yet incorporate MAMR, it does couple PMR with TDMR (two-dimensional magnetic recording), which gives a slight boost to platter density, reaching over 900 Gbit/sq. inch. The DC HC530 naming is a departure from the previous HGST Ultrastar line products, which were labeled as 'He8', 'He10', etc. High-level specs are as follows:

  • Rotational speed: 7200 RPM
  • Data buffer: 512MB
  • Seek time (typ): 7.5 ms
  • Sequential transfer rate: 267 MB/s (start of disk)
  • Available sector sizes: 512e (advanced format emulation), 4Kn (4KB sectors)
  • Warranty: 5 years

The SAS models offer double the interface throughput (12Gbps) and some additional custom sector sizes but require higher operating power to drive that faster interface. While track linear density is high enough (at least at the start of the disk) to saturate a SATA 3Gbit link, SATA 6Gbit and SAS 12Gbit links will still see a cache-hit benefit from the drives' relatively large 512MB data buffer.

WD's press release appears after the break, and more information is available on the Ultrastar DC HC530 product page.

Toshiba Refreshes HDD Branding, Intros Surveillance and Video Streaming Models

Tagged: x300, V300, toshiba, s300, P300, N300, L200, hdd

Today (well, tonight) Toshiba changed up their HDD branding to make things a bit easier to grasp for the consumer, as well as adding surveillance and video streaming models to their lineup:

2018-04-16-21-48-50.png

Toshiba chose to go with a round of colors, but these are notably different than what you have previously seen from WD. Typical desktop and mobile drives now carry a red label, with their performance desktop model going grey. NAS HDDs are yellow, and the two new items are blue and green. Let's take a closer look at these new additions:

2018-04-16-21-49-12.png

The blue 'Video Stream V300' model comes in up to a 3TB capacity and is firmware optimized for handling multiple (4) simultaneous video streams without thrashing the heads constantly seeking between tracks. This is a low RPM drive and is meant more for use in DVRs. Max capacity comes in only 3TB, but this is a very low cost and low power drive. Note the 'annual workload rating' of 72TB per year. More on that later.

2018-04-16-21-49-02.png

The green 'Surveillance S300' model is meant for significantly more demanding workloads upwards of 64 simultaneous HD video camera streams. These are meant for incorporation into large arrays and come with the necessary RV (accelerometer) sensors to help keep the heads on track while the drive is subjected to harsher vibrations seen in large server chassis. These come in up to 10TB with a workload rating of 150TB per year.

2018-04-16-21-49-42.png

Above are the general specs across the entire lineup, and below are the prices for the two new models:

  • V300 Video Streaming
    • 1TB - V300 Video Streaming - $49.99
    • 2TB - V300 Video Streaming - $69.99
    • 3TB - V300 Video Streaming - $89.99
  • S300 Surveillance
    • 4TB - S300 Surveillance - $119.99
    • 5TB – S300 Surveillance - $149.99
    • 6TB - S300 Surveillance - $189.99
    • 8TB - S300 Surveillance - $249.99
    • 10TB - S300 Surveillance - $349.99

Those prices look very competitive, but that 'annual workload rating' troubles me a bit, especially for the S300. That model is meant for use in an array, which must be initialized (eating one full drive write), possibly migrated (eating another full drive capacity worth of access), and with some RAID controllers, periodically scrubbing the data to verify integrity. A large array of 10TB HDDs with periodic array scrubbing/integrity checking scheduled every 2-3 weeks will technically run these parts past their rated workload. Backing off to monthly checks will get you just under the limit, provided your actual video workload does not push you over. Just something to consider when specing out a surveillance unit build.

Press blast for these new models appears after the break.

Introduction, Specifications, and Packaging

Introduction

A while back, we reviewed the ICY DOCK ToughArmor MB998SP-B and MB993SK-B hot-swap SATA docks. These were well built, high-density docks meant for 7mm height SSDs and HDDs. The former part was unique in that it let you squeeze eight drives in a single 5.25” drive bay, all while enabling you to hot swap all of them at the front panel. The ToughArmor line has been pushing into higher and higher bay counts, so it only made sense that we eventually saw something higher than an 8-bay unit:

180402-112507.jpg

Enter the ToughArmor MB516SP-B. While it looks like two MB998SP-B’s stacked on top of each other, there is more than meets the eye in order to pull this trick off properly. We'll focus on that further into the review, but for now, let us get through the specs.

Tagged: SSD EX920, NVMe, hp, tlc, SM2622, M.2

HP have released a new NVMe M.2 SSD, the EX920 which uses Silcon Motion's SM2622 controller and a DDR3-1600 cache which scales directly with the size of the drive, the 256GB drive has a 256MB cache while the 2TB has 2GB.  The drive uses four PCIe Gen 3 lanes, which offers some very impressive performance, Benchmark Reviews measured 3183/1776 MBps read/write in CrystalDiskMark.   The only real drawback to this drive is the warranty; while most companies offer at least five years, this HP drive is only covered for three.

hpspecs.PNG

"HP suggests sustained sequential read speeds up to 3200 MB/s, and sustained sequential writes up to 1800 MB/s from their 1TB EX920 SSD, which utilizes 64-layer 3D NAND to deliver impressive storage density and reliability. Relative to solid state storage, one terabyte is an enormous amount of near-instant drive capacity. We’ll see if HP’s EX920 M.2 SSD is worth the money."
