The Legend 970 is ADATA's first crack at the slowly growing PCIe Gen 5.0 market segment. The drive uses a combination of a Phison controller and 232-layer NAND and comes with an active cooling solution. We review the 2TB model, landing at just under £300 here in the UK. 

ADATA's Legend 970 product comprises (at the time of writing) just two models, a 1TB drive and the flagship 2TB unit (the drive ADATA kindly supplied for review). At the heart of the drive is a Phison PS5026 E26 8-channel controller looking after 232-layer Micron 3D TLC NAND and 4GB of LPDDR4-4266 DRAM cache.

Sequential performance for the 2TB drive is quoted as up to 10,000MB/s for both read and writes while 4K random performance is listed as up to 1,400,000 IOPS for both. The 1TB drive gets ratings of up to 9.500MB/s and 8,500MB/s for Sequential read/writes respectively while 4K random read performance is quoted at 1,300,000 IOPS with random writes at 1,400,000 IOPS as per the 2TB drive.

Endurance is listed as 700 TBW and 1400 TBW for the 1TB and 2TB models respectively and ADATA backs the drive with a 5-year warranty.
