Earlier this year, Biwin started to sell its range-topping X570 Pro SSD with a PCIe 5.0 x4 based on SMI's SM2508 controller, putting itself on the map of the highest-end drives. Now, the company is seeking to address a demanding, yet more price-critical market segment with the vanilla X570 SSD that the company launched at Computex 2025. Despite the name, this is not a simplified version of the X570 Pro, but a drive based on a completely different PCIe Gen5 platform that can still deliver up to 14,500 MB/s sequential read speed.
Biwin's Black Opal X570 is one of the first high-end SSDs based on Maxio's MAP1806 controller that has eight NAND channels and supports 3D TLC NAND memory with an up to 3600 MT/s interface. Biwin's X570 is said to offer an up to 14,500 sequential read speed (the maximum read performance supported by a PCIe 5.0 x4 interface) and an up to 11,000 MB/s sequential write speed, which is 2,000 MB/s or 3,000 MB/s below today's best SSDs. As for random performance, we are talking about up to 2 million read IOPS and up to 1.5 million write IOPS.
