It comes in a 2.5-inch, 7 mm form factor, making it compatible with a wide range of systems that accept standard SATA drives. This SSD delivers SATA-level performance, with sequential read and write speeds up to about 500 MB/s, significantly faster than traditional hard disk drives and close to the maximum throughput of the SATA interface. It also offers strong random performance, with around 90,000 IOPS for random reads and ~30,000 IOPS for random writes, enhancing responsiveness for multitasking and enterprise workloads.
