Toshiba XG3 M.2 NVMe SSD Review (1TB) – Rocket Ship NVMe SSD


It goes without saying that Samsung is rather fortunate that Toshiba hasn’t pushed the XG3 family as a consumer SSD; the Toshiba XG3 M.2 1TB NVMe SSD is a rocket ship storage device.  We actually never started testing with any sort of comparison in mind, or even a thought that the XG3 might stand beside the 950 Pro, much less prove to be the victor.  In the end, it is clearly the top dog on the block.

When we examine the overall performance, it is obvious right off that Toshiba undercut their specifications, minimally albeit, but gaining results of 2.7GB/s read and 1.6GB/s write was eye-opening.  These were paralleled by 214K IOPS read and 170K IOPS write which might not achieve top marks in itself, but the fact that both read and write IOPS were equally strong is rare.  This performance was confirmed in both synthetic and real life data transfer testing, followed by some grueling tests in PCMark 8 where the XG3’s low latency became very apparent.

The only hit the Toshiba’s XG3 M.2 NVMe PCIe SSD has against it is that it is not available to the consumer at this time, meaning many will buy this SSD through less than reliable means and forego any type of warranty.  This, of course would be totally dependent on the release of the OCZ RevoDrive 400, which will no doubt end up being the consumer version of the XG3….and has no release date as of yet.  Even considering this, we would be remiss to not afford the Toshiba XG3 1TB NVMe SSD with our Editor’s Choice Award.  It is just that good!

    Thats some pretty good stuff from toshiba. And from 2D MLC flash.

    I do wonder however what controller is that. Obviously its not made by toshiba. Something from OCZ maybe ? Or phison E7?

  3. Bring on the 1Tb M.2 NVME Drives!!! (its the only thing stopping me from dropping a lot of moneys (and selling 1/2 a liver) and getting a new Rig.

  4. Your claim for Crystal Disk Benchmark is several times higher than mine, on my 2013 Dell XPS-15 notebook computer. The original factory mSATA SSD was replaced a few months ago with a terabyte Samsung 850 EVO.

    How comparable are the results of your tests, compared to those of your readers? If I install one of your tested products, how much performance difference should we expect? Several times?

    My next upgrade might be to replace to original terabyte spinning HDD with a SSD of one or two terabytes. Perhaps.

    • The Samsung 850 EVO SSD (mSata) uses the mSata Standard and can not go as fast as the drives in this review.

      The Drives in this review are M.2 (PCIE NVME) SSD’s and have access to 4 PCIE lanes which is Considerably much faster than Sata be it on: mSata on mini-pci(e) or M.2

    • You should’ve bought an M.2 or PCIE SSD if you wanted pure speed and didn’t care about the cost.

    • All I will say is you can’t really get away with comparing mSATA or SATA against PCIe storage. Its kinda like comparing PCIe video cards to AGP video cards, or even PCI to PCIe, it just isn’t a fair comparison. The PCIe bus is magnitudes better at moving data than the SATA bus will ever be. Now if you want to put FOUR 850 EVOs into RAID0, then we can talk comparisons because that MIGHT (I stress might, lol) compete with the single PCIe SSD given the usage scenario.

  5. The advice to disable cache flush is wrong. You should only mark this option is the SSD has capacitors to protect unflushed data on power loss. So the drive runs faster but Your data is not safe, this is trade off. pease be aware of that. if the performance without this option is low then the controller or firmware is not well designed or… other controllers do not respect host request to flush cache. Do You have any information what is the real issue? Regards

  6. The SSD folks who improve performance by playing games with memory inherently increase the risk of data loss if the devices lack supercaps and ECC RAM. The topic of ECC RAM has never come up here but when the enterprise SSD/NVMe sizes climb into the Ts its a more valid concern. I’m not even sure if controllers can even catch internal bit errors in the RAM cache. I’ve never heard of ECC being available in single DRAMs.

  7. Does this fit into a hp omen?

  8. Guys. Thanks for an awesome review. Does anyone know where I can get the PCIe to USB 3.0 or to SATA adapter so I can get my data off this drive? I have a Dell XPS 15″ laptop that I paid $3,400 for and it won’t even turn on. Dell told me to take it to a local computer support specialist. Any help would be appreciated. EVERY SSD to USB adapter I found does not work with the M.2 Type 2280 NVMe pcie solid state interface. =-(

  9. Hello have this drive ona Lenovo x1 (Gen 3) and have no way to get it accepted. 2103 Detection Error , and than in the installation process which starts Hardware is not supported… Any help for that issue (love that drive for what it is, just want it installed ) Thanks
