We recently looked at the flagship 4TB drive of Biwin's new Black Opal X570 PRO (HERE) Gen 5 drive range. Now, we are looking at the drive in the middle of the range, the 2TB X570 PRO.

At the heart of the X570 PRO is a new controller we've not come across before from Silicon Motion, the SM2508. The SM2508 is an 8-channel controller designed to offer high-end performance together with power efficiency achieved by a 6nm build process and a Flash interface running at a full 3,600 MT/s speed. For the X570 PRO Biwin has combined the controller with 232-layer TLC NAND.

The 2TB drive is the middle drive of a three-drive line up, the other drives being the 1TB and 4TB capacities. The 2TB drive is officially rated at up to 14,000MB/s for Sequential reads and up to 13,000MB/s for writes. Incidentally, the other two drives are also rated at up to 14,000MB/s for reads with the 4TB drive getting the same 13,000MB/s write figure as the 2TB drive with the 1TB drive back at up to 10,500MB/s.

Random reads for the 2TB drive are quoted as up to 2000K IOPS with writes at up to 1600K IOPS. The other two drives have the same write speed with the 4TB drive rated as up to 2000K for reads and the 1TB drive up to 1600K IOPS.

The endurance figure quoted for the 2TB drive is 1,500 TBW with the 4TB model at 3,000 TBW and the 1TB drive 750 TBW. The drives are backed by a 5-year warranty.
