Techreport has posted a review of the Toshiba XG5 1TB NVMe SSD. This is not your regular retial product, but rather an OEM version. Still this thing is FAST!
This review will be a bit different from our usual fare, since the XG5 isn’t a retail drive. Toshiba’s XG line is sold to OEMs and system integrators rather than directly to consumers. Regardless of its target audience, the XG5 is a PCIe 3.0 x4 NVMe drive with Toshiba’s 64-layer BiCS NAND and a Toshiba controller running the show. For now, the drive is being produced in 256GB, 512GB, and 1TB flavors, but Toshiba tells me nothing is stopping it from making a whopping 2TB version if one of its partners asks for it.
Toshiba’s XG5 almost uniformly improved on the RD400 throughout our test suite, which is exactly what Toshiba set out to do with the drive. It couldn’t dethrone Samsung’s V-NAND in many of our tests, however, so it’s likely that the XG5 won’t set an overall performance record. We distill the overall performance rating using an older SATA SSD as a baseline. To compare each drive, we then take the geometric mean of a basket of results from our test suite. Only drives which have been through the entire current test suite on our current rig are represented.
