Biwin unveiled the Black Opal X570 Pro, a brand-new PCIe 5.0 SSD that nearly fully utilizes the PCIe 5.0 interface and achieves sequential read rates of up to 14,000 MB/s, at Computex 2025. The M.2 2280 SSD has a capacity of 1TB, 2TB, and 4TB and is connected via four PCIe 5.0 channels.

The Silicon Motions SM2508 SSD controller, which Biwin supplies with a DRAM cache to buffer write access, is included with the Pro model. For every 1 TB of storage space, there is 1 GB of cache. This indicates that while the 1TB version of the X570 Pro (with only 1GB cache) doesn’t surpass 12,000 MB/s, the 2TB and 4TB models can achieve sequential write speeds of up to 13,000 MB/s. Up to 1.6 million input and output commands per second (IOPS) for random writing and 2 million IOPS for reading are claimed by Biwin for their new SSD.

A slightly less expensive variant, the Black Opal X570, is also planned by Biwin. It does away with the extra DRAM cache and buffers write access in a designated memory space area, which is subsequently addressed as an SLC cache, which reduces writing speed. Up to 7,800 MB/s (1TB model), 10,000 MB/s (2TB model), and 11,000 MB/s (4TB model) are the maximum sequential write speeds specified by Biwin. At 14,000 MB/s, 14,500 MB/s, and 14,500 MB/s, respectively, sequential read rates are quite high.

The three storage capacities for random read and write also varied significantly. 1.6 million input and 1 million output commands per second are achieved by the 1TB model, 2 million input and 1.4 million output by the 2TB model, and up to 2 million input and 1.5 million output by the 4TB model.
