A month ago, WD and Toshiba each put out releases related to their BiCS 3D Flash memory. WD announced 96 layers (BiCS4) as their next capacity node, while Toshiba announced them reliably storing four bits per cell (QLC).

WD recently did their own press release related to QLC, partially mirroring Toshiba's announcement, but this one had some additional details on capacity per die, as well as stating their associated technology name used for these shifts. TLC was referred to as "X3", and "X4" is the name for their QLC tech as applied to BiCS. The WD release stated that X4 tech, applied to BiCS3, yields 768Gbit (96GB) per die vs. 512Gbit (64GB) per die for X3 (TLC). Bear in mind that while the release (and the math) states this is a 50% increase, moving from TLC to QLC with the same number of cells does only yields a 33% increase, meaning X4 BiCS3 dies need to have additional cells (and footprint) to add that extra 17%.

The release ends by hinting at X4 being applied to BiCS4 in the future, which is definitely exciting. Merging the two recently announced technologies would yield a theoretical 96-layer BiCS4 die, using X4 QLC technology, yielding 1152 Gbit (144GB) per die. A 16 die stack of which would come to 2,304 GB (1.5x the previously stated 1.5TB figure). The 2304 figure might appear incorrect but consider that we are multiplying two 'odd' capacities together (768 Gbit (1.5x512Gbit for TLC) and 96 layers (1.5x64 for X3).

Toshiba and Western Digital announce QLC and 96-Layer BiCS Flash

A couple of announcements out of Toshiba and Western Digital today. First up is Toshiba announcing QLC (4 bit per cell) flash on their existing BiCS 3 (64-layer) technology. QLC may not be the best for endurance as the voltage tolerances become extremely tight with 16 individual voltage states per cell, but Toshiba has been working on this tech for a while now.

In the above slide from the Toshiba keynote at last year's Flash Memory Summit, we see the use case here is for 'archival grade flash', which would still offer fast reads but is not meant to be written as frequently as MLC or TLC flash. Employing QLC in Toshiba's current BiCS 3 (64-layer) flash would enable 1.5TB of storage in a 16-die stack (within one flash memory chip package).

Next up is BiCS 4, which was announced by Western Digital. We knew BiCS 4 was coming but did not know how many layers it would be. We now know that figure, and it is 96. The initial offerings will be the common 256Gbit (32GB) capacity per die, but stacking 96 cells high means the die will come in considerably smaller, meaning more per wafer, ultimately translating to lower cost per GB in your next SSD.

While these announcements are welcome, their timing and coordinated launch from both companies seems odd. Perhaps it has something to do with this?

Computex 2017: Western Digital Launches Client SSDs Sporting 64-Layer NAND

Subject: Storage | May 29, 2017 - 11:42 PM |
Tagged: western digital, wdc, WD, Ultra, ssd, sandisk, nand, computex 2017, Blue, BiCS, 3d

Western Digital bought SanDisk nearly two years ago, but we had not really seen any products jointly launched under both brand labels. Until today:

PRN-Graphic_3D-NAND.jpg

The WD Blue 3D NAND SATA SSD and SanDisk Ultra 3D SSD are both products containing identical internals. Specifically, these are the first client SSDs built with 64-layer 3D NAND technology. Some specs:

  • Sequential read: 560 MB/s
  • Sequential write: 530 MB/s
  • Capacity: 250GB, 500GB, 1TB, 2TB
  • Form factor: 2.5" (WD and Sandisk), M.2 (SATA) 2280 (WD only)

MSRP's start at $99.99 for the 250GB models of all flavors (2.5" / M.2 SATA), and all products will ship with a 3-year warranty.

It might seem odd that we see an identical product shipped under two different brands owned by the same company, but WD is likely leveraging the large OEM relationship held by SanDisk. I'm actually curious to see how this pans out long term because it is a bit confusing at present.

Western Digital Launches 10TB Red and Red Pro

Subject: Storage | May 17, 2017 - 09:57 PM |
Tagged: western digital, wdc, WD, Red Pro, red, NAS, helium, HelioSeal, hdd, Hard Drive, 10TB

Western Digital increased the capacity of their Red and Red Pro NAS hard disk lines to 10TB. Acquiring the Helioseal technology via their HGST acquisition, which enables Helium filled hermetically sealed drives of even higher capacities, WD expanded the Red lines to 8TB (our review of those here) using that tech. Helioseal has certainly proven itself, as over 15 million such units have shipped so far.

We knew it was just a matter of time before we saw a 10TB Red and Red Pro, as it has been some time since the HGST He10 launched, and Western Digital's own 10TB Gold (datacenter) drive has been shipping for a while now.

  • Red 10TB:        $494
  • Red Pro 10TB: $533

MSRP pricing looks a bit high based on the lower cost/GB of the 8TB model, but given some time on the market and volume shipping, these should come down to match parity with the lesser capacities.

Tagged: WD, ssd, external ssd

Western Digital has just announced the My Passport SSD line of portable solid state hard drives. As you might expect, the major advantage of SSD-based portable storage is speed. This one connects with a USB Type-C port and is rated at up to 515 MB/s, although that hasn’t been benchmarked yet. The drives also support hardware, 256-bit AES encryption via their security software.

wd-2017-mypassportssd.png

According to Best Buy, the 256GB model ($99.99 USD) is already sold out, but the 512GB model ($199.99) and the 1TB model ($399.99) are both still available for the 14th of April.

CES 2017: Western Digital Launches WD Black NVMe PCIe SSD

Following up on their Blue and Green SSDs launched back in October, Western Digital has now launched a Black series SSD:

170105-014630.jpg

Unlike the Green and Blue which are SATA products available in 2.5" and M.2 (SATA) form factors, the Black is a pure M.2 NVMe PCIe 3.0 x4 product. These were rumored to have a Marvell controller, but the samples I saw floating around CES appeared to have SanDisk branding. Flash will very likely be SanDisk 15nm TLC (with SLC cache). Specs are as follows:

  • 256GB / 512GB
  • $109 / $199 ($0.42 / $0.39 / GB)
  • Random read: 170k
  • Random write: 130k/134k
  • Sequential read: 2.05 GB/s
  • Sequential write: 700 / 800 MB/s
  • Endurance 80 / 160 TBW
  • Warranty: 5 years
  • Power: 5.5 mW idle / 8.25 W peak

Pricing looks very competitive for an NVMe SSD, but we will have to see how the performance shakes out when compared against other budget SSDs. The WD Blue 1TB performed very well in our new test suite, so here's hoping the Black is equally surprising.

WD's press blast appears after the break.

Since their acquisition of SanDisk and recent wrapping up of a long-time integration with HGST's Helium tech, Western Digital took the lid off of a round of product updates this morning.

wd-9-.png

First up is a second generation of HGST-branded SSD products - the Ultrastar SN200. These enterprise SSDs boast impressive specs, pushing random reads beyond 1 million IOPS, coming in 8TB capacity, and if you opt for the HHHL PCIe 3.0 x8 SN260, 6.2GB/s maximum throughput.

wd-11-.png

Moving into SAS SSDs, the SS200 uses a 12Gbit link to achieve 1.8 GB/s and 250,000 random read IOPS. Write specs dip to 37,000 random as this is a 1 DWPD endurance class product. These are also available in up to 8TB capacities.

wd-16-.png

Last but certainly not least are preliminary specs for the He12, which boast particularly impressive low QD random write performance and a notable bump in Watts/TB despite the addition of an eighth platter to achieve the 12TB capacity. Note that this is not an archive class product and is meant for continuous random access.

wd-14-.png

There is also a 14TB model in the lineup, but that is an archive class model that is essentially the He12 with Shingled Magnetic Recording enabled.

UltrastarHe12-SN200-SS200-Press-300dpi.jpg

Not bad HDD progress considering we were just discussing 10TB SMR this time last year. We'll be confirming the performance of these as samples arrive for testing.

Western Digital Gets Back in the SSD Game With Blue and Green SSDs!

Subject: Storage | October 11, 2016 - 11:50 AM |
Tagged: western digital, wdc, WD, ssd, Green, Blue

It has been over 6 years since we saw an SSD come out of Western Digital, but we suspected some new ones may be coming after their recent acquisition of SanDisk. That say has come, and today we have two new SSD models announced by WD:

wdfWDBlueSSD.jpg

These new SSDs naturally borrow SanDisk 15nm TLC flash but drive that flash with aftermarket controllers. The Blue employs a Marvell 88SS1074 controller while the Green will use a Silicon Motion SM2256S. The Blue will have the typical SATA 6Gbps saturating specs seen in modern SSDs, while the Green will be derated a bit. Detailed specifications are below:

  • Form Factors: 2.5¨/7mm cased, M.2 2280
  • Endurance (Blue):
    • 250GB: 100 TBW
    • 500GB: 200 TBW
    • 1TB: 400 TBW
  • Power (Blue):
    • Slumber: 42mW-52mW
    • DEVSLP: 4.9mW-9.7mW
    • Average Active Power: 70mW
  • Warranty (Blue and Green): 3 years

WD Blue SSD Specs.png

The WD Green will be more budget minded and is to be offered in only a 120GB and 240GB form factor, with reduced endurance ratings of 40 TBW and 80 TBW, respectively.

Pricing (for the WD Blue SSD):

  • 250 GB $79.99
  • 500 GB $139.99
  • 1TB $299.99

WD Blue WD Green SATA 1.png

The WD Green SSD will be available 'later this quarter', and we do not yet have pricing for that model, but it should come in at a lower cost than the Blue prices above. We have a Blue model in for testing and should see how it fares on our new storage suite later this week.
