fanxiang S501 512GB

The fanxiang S501 512GB is a solid-state drive in the M.2 2280 form factor, designed for systems with an NVMe slot supporting PCIe 3.0 x4. It uses TLC NAND flash memory and is controlled by a Silicon Motion SM2263XT controller, which is a DRAM-less design. The drive features an approximate 128 GB pSLC cache to boost write performance. In terms of performance, the S501 achieves sequential read speeds of up to 2150 MB/s and sequential write speeds of up to 1600 MB/s. Random read performance is rated at 124,613 IOPS, while random write reaches 202,687 IOPS. These specifications make it suitable for general computing and storage tasks in compatible desktop or laptop systems. The drive is intended for use in motherboards or laptops that accept M.2 2280 NVMe drives and support PCIe 3.0 x4. It does not include a DRAM cache, relying instead on host memory buffer (HMB) technology for metadata handling.
