NAS caching drive

The SanDisk Red SA500 is a 2TB M.2 2280 internal SSD built on 3D NAND with a SATA interface. It targets home and business NAS appliances that need a dedicated cache tier for frequently accessed files. The drive is rated for continuous operation in 24/7 environments. Its form factor fits the M.2 slots found in modern NAS units.

Sustained write behaviour

Sequential writes reach up to 530 MBps while random 4KB writes hit 85000 IOPS. Power draw under maximum write load is 3800 mW, well within typical NAS power budgets. The drive maintains these figures across extended workloads such as OLTP databases, multi-user file serving and 4K or 8K video editing. MTTF of up to 2M hours reflects the endurance tuning for heavy, constant I/O.

SATA throughput ceiling

The SATA III link caps sequential reads at 560 MBps and writes at 530 MBps regardless of the NAND speed. If your NAS can use a faster protocol, this drive will become the bottleneck. For SATA-only bays the drive delivers the maximum throughput the bus allows.

Questions about this item

Will this M.2 drive fit my NAS slot?

The drive uses the M.2 2280 form factor, which is the standard 80 mm length used in most modern NAS units with an M.2 slot.

Can I use this as a cache drive for my NAS?

Yes, the Red SA500 is designed for NAS caching to accelerate access to frequently used files in 24/7 environments.

What power draw should I expect under heavy writes?

Maximum write power is 3,800 mW, while idle slumber power is 56 mW and DEVSLP is 5-12 mW.
