After teasing with a demo earlier this month at the Dell EMC World conference, Toshiba is now officially announcing their first SSD based on their 64-layer BiCS3 3D NAND. This is the first generation of Toshiba 3D NAND that will be adopted across their entire range of SSDs, and the first product to get the new flash is a consumer-oriented M.2 NVMe SSD. The Toshiba XG5 is the direct successor to the XG3 and will occupy the highest of Toshiba's three tiers of client OEM SSDs. While the XG3 and its retail sibling the OCZ RD400 used planar MLC NAND, the XG5 uses 3D TLC NAND but still promises higher throughput. The Toshiba XG4 was the TLC-based counterpart to the XG3, and its role as the entry-level NVMe drive will be taken over by the BG-series NVMe BGA SSDs, while SATA SSDs will continue to be the lowest tier of Toshiba OEM SSDs.
