The Toshiba XG3 SSD is a M.2 NVMe drive which just may be the most powerful SSD on the market?.well not really on the market. It isn't available through consumer sales and can only be found pre-installed in ultrabooks, unless of course you are lucky enough to dig one up on eBay. The downfall of trying to get ones hands on such a OEM/client SSD that is not attained pre-configured in a new system, of course, is that there is no warranty. It is the chance you take and the trade-off for owning the best. On our test bench today is the 1TB capacity Toshiba XG3 M.2 NVMe PCIe SSD and we will be the first to admit that this SSD's performance was totally unexpected.
