Flash NAND producer Kioxia has announced that it is preparing the BG6 Series of client SSDs. These are touted to deliver an impressive 1.7x performance uplift compared to the previous gen (BG5). Kioxia boasts that the BG6 Series SSDs also double the max capacity to 2TB, while maintaining the compact M.2 2230 form factor. It will also be making M.2 2280 single-sided form factor versions of the BG6 available.
Kioxia BG6 M.2 2230 SSDs use the PCIe Gen4 x 4 interface and are claimed to deliver data transfers speeds of up to 6.0 GB/s read and 5.3 GB/s write, with I/O performance of up to 900,000 IOPS. The only hardware change flagged by Kioxia — which may well be instrumental to the new faster performance, increased density, and plus improved power efficiency — is the transition to the firm's 6th Generation BiCS Flash 3D NAND chips. These new drives are DRAM-less, but use Host Memory Buffer (HMB) technology for caching.
