NAS-optimised caching drive

The Western Digital Red SA500 WDS200T1R0A is a 2TB 2.5-inch internal SSD built for network-attached storage. It uses 3D NAND and a SATA III interface to accelerate access to frequently used files in home or small-business NAS units. The drive is rated for 24/7 operation with an MTTF of up to 2M hours.

Suited for NAS caching, not primary bulk storage

This SSD targets users who need a high-endurance cache tier for OLTP databases, multi-user workloads, photo rendering or 4K and 8K video editing. It is less appropriate for archival-only arrays where sequential throughput matters more than random IOPS and low latency.

SATA III interface decides compatibility

The drive connects through a standard SATA III port and delivers up to 560 MBps sequential read and 530 MBps sequential write. Random performance reaches 95,000 IOPS read and 85,000 IOPS write. Systems without a 2.5-inch SATA bay or a compatible SATA controller cannot use this drive.

Perguntas sobre este artigo

Will this 2.5 inch drive fit the drive bays in my Synology or QNAP NAS?

The drive uses the standard 2.5 inch SATA form factor, which matches the drive trays in most modern Synology, QNAP, Asustor and TerraMaster NAS units that accept 2.5 inch drives.

Can I use this SSD as a read-write cache to speed up my mechanical NAS volumes?

Yes, the drive is optimized for NAS caching workloads with up to 95,000 random read IOPS and 85,000 random write IOPS to accelerate frequently accessed files and databases.

How much power does the drive draw during heavy write activity?

Maximum write operating power is 3,800 mW, while idle slumber power is 56 mW and DEVSLP drops to 5-12 mW for low standby consumption.
