NAS-ready M.2 SATA SSD

This SanDisk 1TB internal solid-state drive uses the M.2 2280 form factor and a SATA interface. It is built with 3D NAND and designed for caching workloads in network-attached storage systems. Home and business users who need reliable 24/7 operation will find it suited to their NAS slots.

Built for continuous NAS duty

The drive carries a 2M-hour MTTF rating and is engineered to withstand heavy read and write loads typical of always-on environments. Its M.2 2280 connector fits directly into compatible NAS bays without a 2.5-inch carrier. Operating temperatures from 0°C to 70°C and 1,500G shock resistance support dependable day-to-day use.

560 MB/s sequential read ceiling

Maximum sequential read reaches 560 MBps and sequential write reaches 530 MBps over the SATA link. Random performance is rated at 95,000 IOPS read and 85,000 IOPS write. These figures determine whether the drive can keep pace with multi-user databases, photo rendering or 4K and 8K video editing workloads.
