Manufacturer description
The fanxiang S101 brings 4TB of SATA storage to any desktop or laptop that still has a 2.5-inch bay, and it does it without asking you to open your wallet for an NVMe upgrade path your machine may not support. Read speeds top out around 500MB/s, which is the practical ceiling of the SATA III 6Gb/s interface, so this drive is saturating the bus rather than leaving performance on the table. fanxiang cites at least 50% faster boot times versus a mechanical hard drive, and the 3D NAND with SLC caching keeps everyday file transfers snappy under mixed workloads. The reliability feature set is more…
