The latest drive from Kioxia is the Exceria PRO G2, the new flagship model for the company's consumer range. The Gen 5 drive, which uses a combination of an 8-channel controller and 218-layer NAND, is Kioxia's fastest drive to date, rated up to 14,900MB/s and 13,700MB/s for sequential read and writes, respectively.
At the time of writing, the Exceria PRO G2 lineup consists of three capacities: 1TB, 2TB and the flagship 4TB model (the drive we are looking at here). At the heart of the drive is a Silicon Motion SM2508 8-channel controller paired up with Kioxia's BiCS8 218-layer 3D TLC NAND.
Kioxia rates the Sequential performance of the 4TB Exceria PRO G2 as up to 14,900MB/s for reads and up to 13,700MB/s for writes. The 2TB drive gets the same read rating as the 4TB drive, while the 1TB is rated up to 14,400MB/s. When it comes to write performance, the 2TB drive is rated up to 13,400MB/s and up to 12,700MB/s for the 1TB model.
Random performance for the 4TB drive is quoted as up to 2,300,000 IOPS for reads and up to 1,950,000 IOPS for writes. The 2TB drive is rated up to 2,250,000 IOPS and up to 1,950,000 IOPS for read and writes, respectively, while the 1TB gets 2,000,000 IOPS for reads and 1,900,000 IOPS for writes.
The 4TB drive gets a TBW endurance rating of 2,400TB, while the 2TB gets 1,200TB, and the 1TB gets 600TB.
Kioxia backs the drives with a 5-year warranty.
