Toshiba today introduced the XG6 series SSDs. Built in the M.2-2280 form-factor with PCI-Express 3.0 x4 interface, the drives take advantage of the NVMe 1.3a protocol, and succeed the XG5 series from 2017. The drives implement Toshiba's new 96-layer 3D TLC NAND flash dubbed BiCS Flash, which went into mass-production in Q1-2018. Available in 256 GB, 512 GB, and 1 TB capacities, the drives offer sequential transfer rates of up to 3,180 MB/s reads, with up to 2,960 MB/s writes. Also on offer are 4K random access transfer rates of up to 355,000 IOPS reads, with up to 365,000 IOPS writes. The drives are expected to be backed by 5-year warranties, when they go on sale at prices competitive with the likes of Samsung's 970 EVO series.
