On the eve of Flash Memory Summit (August 11-13), Toshiba has announced a full range of NVMe-based PCIe SSDs using Toshiba controllers and Toshiba MLC flash.

Toshiba NVMe Drive Families
Drive Series PX04P XG3 BG1
Form Factors and Interface PCIe 3.0 x4 HHHL /
2.5” U.2
PCIe 3.1 x4 M.2 2280 / 2.5” SATA Express M.2 2230 /
16mm*20mm soldered module "M.2 1620"
Capacities 800 GB, 1600 GB, 3200 GB Up to 1024GB Up to 256 GB
QSBC Error Correction Yes Yes No
TCG Pyrite Security No Yes Yes
Sequential Read 3100 MB/s ? ?
Sequential Write 2350 MB/s ? ?
4kB Random Read IOPS 660k ? ?
4kB Random Write IOPS 185k ? ?

For the enterprise market, the PX04P series complements the SAS-based PX04S drives announced last week. The PX04P is available as a 2.5” drive with a U.2 (SFF-8639) connector, or as a PCIe expansion card. In either case, the drive supports four lanes of PCIe 3.0 and can make good use of that bandwidth to offer up to 3.1 GB/s sequential read speeds. With an endurance rating of 10 drive writes per day it is intended for relatively write-heavy workloads.

For the high-performance client market, the XG3 is available in the M.2 2280 form factor using four lanes of PCIe 3.1, or as a 2.5” drive using the two-lane SATA Express connector. If these drives make it in to the retail channel, it means that consumers whose motherboards have a SATA Express connector but no M.2 slot will finally have an easy way to get in on the PCIe storage revolution.

For tablets and ultra-thin laptops, the BG1 is optimized for low power in very small packages. It comes as either an M.2 2230 card or a soldered-down module measuring 16mm by 20mm. The BG1's maximum capacity is only 256 GB, and given the power and size constraints it is probably not using a 4-lane PCIe connection.

The two client drive families implement support for the Trusted Computing Group Pyrite standard, a subset of TCG Opal that includes features necessary for things like secure boot but does not include encryption.

    If you have to ask you can't afford it :)

    Seriously, why leave out something so obvious. If they can't include the price, why bother writing the article. As far as I am concerned it's vaporware, until I see a price.

    These are OEM drives, hence pricing is highly dependent on volume and the terms of the contract. I.e. you won't be able to buy these drives anyway, although the XG3 is likely the Toshiba-based NVMe drive OCZ teased at Computex and will retail under the RevoDrive brand.

    I wonder if it's worth reporting about these at all. You can't actually buy them. And OEMs don't tell you what drive they integrated into their systems so even if you happen to buy a system with one of these inside, you probably won't even know it.

    The SM951 is a OEM drive, yet one runs in my PC just fine. There is always shops that sell OEM components if there is interest on the market.

    So if we can't buy them, its not worth knowing?? Really.......so a new product line\launch\direction shouldn't be reported simply because its not consumer based? Wow.....
  • bug77 - Tuesday, August 11, 2015 - link

    I would guess the audience for that on _consumer_ oriented site is rather limited, yes.
    I may be wrong, I was just asking whether it made sense to report.
  • edzieba - Tuesday, August 11, 2015 - link

    This is a technology oriented site, not consumer oriented. Sure, we like the new shiny things you can wander down to a brick-and-mortar store to buy, but we're also interested in more esoteric technology. that's trickier to get a hold of.

    I have a Samsung SM951 as a datadisk in Ubuntu Linux OS. Can't get it to boot on three MBs I have. I await for an NVMe version to appear and hopefully one will.

    Does grub detect it? Maybe just have /boot + grub on a separate device.
