Introduction and Specifications


It has been a while since we took a look at some hard drives here at PC Perspective. While seemingly everyone is pushing hard into Solid State Storage, those spinning platters have gotten the computer industry by for several decades, and they won't be going away any time soon so long as magnetic domains can store bits for cheaper than electrons can. SSDs have been eating away at the market for OS and single drive mobile needs, but when it comes to bulk storage, nothing beats a great hard drive for the money. Since many users would rather avoid maintaining a large array of drives, getting the capacity of each 3.5" unit higher is still a need, especially for storage hungry consumers. Enterprise units have been pushing into 8TB territory lately, but the consumer sweet spot currently remains at 6TB. Western Digital entered this area in July of last year, pushing their popular Green and Red lines up to 6TB. While the capacity was great, those two lines are mean to be power saving, slower spinning drives. When platter speeds are low, the laws of physics (and of rotational latency) kick in and dictate that they could never perform as well as their 7200 RPM counterparts.


...and now they have filled that gap, with their Black and Red Pro models now made available in up to 6TB capacities. To clarify the product lines here, the Green and Black products are intended for usage as a single drive, while the Red and Red Pro are meant for operating in NAS devices and use in a RAID. The two drives in this review are the faster spinning models, so we should see better performance all around. Spinning those platters faster means more power drawn and more heat generated by air friction across the platters, as we can look into below:


Western Digital Red Pro 6TB:

  • Model: WD6001FFWX
  • Max Sequential Read: 214 MB/s
  • Form Factor: 3.5”
  • Interface Type: SATA 6.0 Gb/s (SATA 3)
  • UBER: <1 in 1015
  • Power (active/idle/standby): 10.6W/7.4W/1.6W
  • Warranty: 5 years

Western Digital Black 6TB:

  • Model: WD6001FZWX
  • Max Sequential: 218 MB/s
  • Form Factor: 3.5”
  • Interface Type: SATA 6.0 Gb/s (SATA 3)
  • UBER: <1 in 1014
  • Power (active/idle/standby): 10.6W/7.6W/1.6W
  • Warranty: 5 years

For comparison, the slower spinning 6TB Red and Green models run at 5.3W/3.4W/0.4W. Lesson learned - moving from ~5400 RPM to 7200 RPM roughly doubles the power draw of a high capacity 3.5" HDD. Other manufacturers are doing things like hermetically sealing their drives and filling them with Helium, but that is a prohibitively expensive proposition for consumer / small business drives, which is what the Black and Red Pro lines are meant to satisfy. It has also been proven that Helium filled drives are not the best if their track geometry is not optimized as well as it could be.

Western Digital Releases My Book Pro - up to 12TB of Thunderbolt Connected Storage

Tagged: western digital, wdc, WD, thunderbolt, My Book Pro

Western Digital has launched a new Thunderbolt RAID-capable external drive called the My Book Pro:


The My Book Pro connects a pair of 3, 4, 5, or 6TB HDD's to a host system via either 20 Gbps Thunderbolt or USB 3.0 (at 5 Gbps). The unit comes preconfigured as a RAID-0 to give full capacities of 6, 8, 10, or 12 TB, but can be switched to RAID-1 or JBOD mode upon connection to a host system. Note that RAID-1 (mirroring) will cut the usable capacity in half - limiting to the capacity of a single drive. As seen above, there are also a pair of USB 3.0 ports at the front of the unit for connecting additional devices to the host via the My Book Pro.


Looking at the rear, we see a pair of Thunderbolt ports (daisy chaining of up to six My Book Pros is supported), as well as a USB 3.0 port.

We are not sure which drives come pre-installed, but the press release clearly states 7200 RPM and since WD just launched a higher capacities of the Red Pro, we'd guess that was their choice here.

Press blast appears after the break.

Seagate Pushes in to 8TB Territory with New Enterprise HDD Models

Just when we were starting to get comfortable with the thought of 6TB hard drives, Seagate goes and announces their lineup of 8TB HDDs:


Now before you get too excited about throwing one of these into your desktop, realize that these models are meant for enterprise and larger NAS environments:


As you can see from the above chart, Seagate will be moving to 8TB maximum capacities on their 'Enterprise NAS' and 'Enterprise Capacity 3.5' models, which are meant for larger storage deployments.

Home and small business users opting to go with Seagate for their storage will remain limited to 4TB per drive for the time being.


For those curious about Kinetic, this is Seagate's push to connect arrays of drives via standard Ethernet, which would allow specialized storage applications to speak directly to the raw storage via standard network gear. Kinetic HDDs are currently limited to 4TB, with 8TB planned this coming January.

Western Digital Updates My Cloud OS3, Refreshes My Cloud Mirror

Subject: Storage | September 1, 2015 - 03:00 AM |
Tagged: western digital, wdc, OS3, My Cloud Mirror

A little over a year ago, we took a look at the Western Digital My Cloud Mirror. This was a simple network connected storage device that came with a suite of software and mobile apps to give remote access to the data stored at home.


Today Western Digital announced a refresh to the My Cloud Mirror. Available for pre-order today and in stores at the end of this month, the new Mirror is essentially just a speed boosted version of the original version (which was no slouch really). Something the added speed may help with is the functionality being added to WD's My Cloud OS software:


The new 'OS3' version adds some requested features, such as using the My Cloud as a hub for syncing across multiple systems (similar to Dropbox, but with your own storage being used instead of their servers).

Another requested feature was the ability to backup and/or offload pictures and videos from mobile devices. This can be done only when connected to WiFi or over cellular data if the user has the GB/month to spare on their data plan.


Another interesting feature is My Cloud Albums. This feature lets you invite your friends/family to share *their* photos / videos from an event. You send them a link and they can then upload their content directly to your My Cloud via their mobile browser or via the My Cloud app (if they have it installed). This sounds like a great idea for collecting photos taken at group events like birthday parties or weddings.

My Cloud OS3 is slated for a 21 September release. We will take a look another look at its features once released.

SanDisk's Ultra II; SSD bargain or not?

Tagged: sandisk, Ultra II, Marvell 88SS9189, Marvell 88SS9190

We've seen Sandisk's Ultra series before but the Ultra II is relatively new to the market.  If anything, they have made the pricing even more attractive, the top end 960GB model is a mere $310, $0.32/GB is getting closer to Ryan's preferred SSD pricing.  As far as the advertised speeds, sequential read and write remain constant at 550MB/s and 500MB/s but IOPS vary by the size of the drive from 81K/80K random read/write for the 120GB model to 99K/83K for the 960GB model.  [H]ard|OCP's testing shows performance more or less in line with the OCZ Trion 100 but somewhat slower than the Samsung 850 EVO, both of which are almost the exact same price.  Check out the full review to see the exact differences, or simply rejoice in the fact that SSDs are approaching prices below $0.30/GB.


"Most of you know that the easiest way to get a performance boost from your old mechanical hard drive is to get rid of it and replace it with a shiny new SSD. SanDisk's Ultra II offers a lot of capacity for the money and comes with a 3 year warranty. Is that enough to compete in a market where prices are falling across every category?"

IDF 2015: OCZ RevoDrive 400 PCIe NVMe Spotted in HHHL and M.2 Packaging

Subject: Storage | August 19, 2015 - 09:41 PM |

While roaming around at IDF, Ryan spotted a couple of new OCZ parts that were strangely absent from Flash Memory Summit:


You are looking at what is basically a Toshiba NVMe PCIe controller and flash, tuned for consumer applications and packaged/branded by OCZ. The only specific we know about it is that the scheduled release is in the November time frame. No specifics on performance yet but it should easily surpass any SATA SSD, but might fall short of the quad-controller-RAID RevoDrive 350 in sequentials.

As far as NVMe PCIe SSDs go, I'm happy to see more and more appearing on the market from every possible direction. It can only mean good things as it will push motherboard makers to perfect their UEFI boot compatibility sooner rather than later.

More to come on the RevoDrive 400 as November is just around the corner!

IDF 2015: Updated: Kingston NVMe PCIe Prototype Shown With New Phison E7 Controller

**Edit** There was some speculation about which controller was in this SSD. It has since been solved. Here's a shot of the top of the PCB:


Now lets compare that with a shot I caught at FMS 2015 last week:


...from the Phison booth. I hadn't wirtten up my Phison post yet but this new Kingston SSD is most certainly going to be using the Phison E7 controller. Here's the placard stating some high level specs:


***end edit***

We saw a draft copy of Kingston’s HyperX Predator at CES 2014. That demo unit was equipped with a SandForce 3700 series controller, but since SandForce never came through on that part, Kingston had to switch gears and introduce the HyperX Predator with a Marvell 88SS9293 controller. The Marvell part was very capable, and the HyperX Predator turned out to be an attractive and performant PCIe SSD. The one catch was that Marvell’s controller was only an AHCI part, while newer NVMe-based SSDs were quickly pushing the Predator down in our performance results.

Kingston’s solution is a newer generation PCIe SSD, this time equipped with NVMe:


We have very little additional information about this new part, though we can tell from the above image that the flash was provided by Toshiba (toggle mode). They also had Iometer running:


We were not sure of the exact workload being run, but those results are in line with the specs we saw listed on Silicon Motion’s SM2260, seen last week at Flash Memory Summit.

We’ll keep track of the development of this new part and hope to see it in a more disclosed form at CES 2016. Kingston's IDF 2015 press blast appears after the break.

IDF 2015: Intel Launches Optane Technology - XPoint for Everyone!

Subject: Storage | August 18, 2015 - 02:20 PM |
Tagged: XPoint, ssd, Optane, Intel, IDF 2015

Just three weeks ago, we reported 3D XPoint Technology. This was a 2-layer stack of non-volatile memory that couples the data retention of NAND flash memory with speeds much closer to that of DRAM.


The big question at that time was less about the tech and more about its practical applications. Ryan is out covering IDF, and he just saw the first publically announced application by Intel:


Intel Optane Technology is Intel’s term for how they are going to incorporate XPoint memory dies into the devices we use today. They intend to start with datacenter storage and work their way down to ultrabooks, which means that XPoint must come in at a cost/GB closer to NAND than to DRAM. For those asking specific performance figures after our earlier announcement, here are a couple of performance comparisons between an SSD DC P3700 and a prototype SSD using XPoint:


At QD=8, the XPoint equipped prototype comes in at 5x the performance of the P3700. The bigger question is how about QD=1 performance, as XPoint is supposed to be far less latent than NAND?


Yes, you read that correctly, that’s 76k IOPS at QD=1. That means only issuing the SSD one command at a time, waiting for a reply, and only then issuing another command. Basically the worst case for SSD performance, as no commands are stacked up in the queue to enable parallelism to kick in and increase overall throughput. For comparison, SATA SSDs have a hard time maintaining that figure at their maximum queue depths of 32.

Exciting to see a follow-on announcement so quickly after the announcement of the technology itself, but remember that Intel did state ‘2016’ for these to start appearing, so don’t put off that SSD 750 purchase just yet.

More to follow as we continue our coverage of IDF 2015!

Western Digital Launches 5TB and 6TB Black and Red Pro

Tagged: western digital, wdc, WD, Red Pro, hdd, Black, 6tb

It's been a while since Western Digital updated their Black series of HDDs, with their 4TB release taking place over two years ago. I'm happy to say that for those looking for a massive HDD suited for holding that enormous games folder too large to fit on your SSD, your wait is finally over, as today WD has updated the Black line to include 5TB and 6TB capacity units.


The Black series introduced that nifty dual stage actuator technology nearly five years ago, and has added a few more bells and whistles along the way. These new models include a 128MB cache and run on dual-core processors.

Along with that news also comes an update to their Red Pro series, which was also limited to 4TB in capacity when they launched last year. Red Pro models will now also include 5TB and 6TB units, so those wanting the most performance and lowest response time from their NAS can now also enjoy that performance at a 50% gain in capacity.


The new 6TB Red Pro also includes a 128MB cache and can peak at 214MB/sec (at the start of the disk). Also included in these is WD's NASware 3.0 firmware, which is specifically tuned to enable packs of these operating in packs while minimizing the effects of vibration on performance.


The 5TB Black comes in at $264 while the 6TB comes in at $294. The Red Pro's come at only an additional $5 over the Black, respectively (small price to pay for better compatibility with larger arrays). Both the Red Pro and Black carry a 5-year warranty.

Press blasts for the 5/6TB Black and Red Pro appear after the break.

FMS 2015: Silicon Motion SM2260 PCIe 3.0 x4 NVMe Controller Spotted

We’ve reviewed a few Silicon Motion SSDs in the past (Angelbird | Corsair Force LX | Crucial BX100), and I have always been impressed with their advances in SSD controller technology. Their SM2246EN SATA controller was launched two years ago, and strived to be a very efficient and performant unit. Based on our reviews that turned out to be true, and this allowed Silicon Motion to slide into the void left by SandForce, who repeatedly delayed their newer developments and forced the many companies who were sourcing their parts to look elsewhere.


The many SSDs using Silicon Motion’s SM2246EN controller.

Silicon motion pushed this further with their SM2256, which we first saw at the 2014 Flash Memory Summit and later saw driving SLC/TLC hybrid flash at this past Consumer Electronics Show. While the SM2256 makes its way into more and more products, I was glad to see an important addition to their lineup at this year’s FMS:


Finally we see Silicon Motion doing a PCIe controller! This is the SM2260, seen here in the M.2 form factor…


…and here in SATA Express. While the latter will likely not be as popular due to the more limited PCIe lanes present in SATA Express, I’m sure we will see this controller appearing in many PCIe devices very soon. The stated performance figures may be a bit shy of currently comparing SSDs like the Intel SSD 750 and Samsung SM951, but with the recent introduction of Z170 motherboards and RST PCIe RAID, it is now easier to RAID a smaller capacity pair of these devices, increasing the performance of slower units. Further, the point of the SM2260 is likely to get a low cost NVMe PCIe SSD controller into the hands of SSD makers, which can only mean good things for those looking to make the move away from SATA.
