@ 2018/03/22Toshiba is announcing a trio of new enterprise SSD models intended for large-scale datacenter deployments. The new CD5, XD5 and HK6-DC respectively use 2.5" U.2, M.2 22110 and 2.5" SATA form factors. The drives use different Toshiba controllers but share an emphasis on read-intensive workloads, with write endurance rated for less than one drive write per day (DWPD). They also lack some of the features of high-end enterprise SSDs, but still include full power loss protection. All three new SSDs use Toshiba's 64-layer BiCS3 3D TLC NAND flash memory.
Toshiba considers their datacenter SSDs and enterprise SSDs to be separate product lines, with the latter being more suited to mission-critical servers and including more high-endurance and high-performance options, and sometimes advanced features like redundant dual-port interfaces. The datacenter drives are aimed at uses like cloud computing infrastructure, where the performance or endurance of an individual drive is less of a concern because the workload is spread over hundreds of SSDs per rack.
