Our Take

Best for: Best for home or small business NAS users needing a fast, reliable cache drive.

The WD Red SA500 is designed specifically for NAS environments, offering superior endurance and reliability for always-on operation. With 1TB capacity and SATA III speeds up to 560 MB/s, it excels as a cache drive or for heavy workloads like databases and 4K video editing. The 48% discount makes it a compelling choice for upgrading your NAS performance. Keep in mind that it uses a SATA interface, so it won't match NVMe speeds, but for NAS applications where SATA is standard, that's not a limitation.

Price Analysis

At $119.99, this is a significant 48% discount from the original $229.99. This price is well below the typical street price for this drive, making it an excellent time to buy for anyone needing a reliable NAS SSD.

Common Questions

Is this SSD suitable for use as a boot drive in a NAS?

Yes, the WD Red SA500 can be used as a boot drive in NAS systems that support SATA SSDs. It is designed for 24/7 operation and offers high endurance.

Does this drive have DRAM cache?

The WD Red SA500 uses a DRAM-less design with Host Memory Buffer (HMB) to the host system's memory for caching. This is typical for SATA NAS SSDs and provides adequate performance for most workloads.

Can I use this in a desktop PC instead of a NAS?

Yes, it works as a standard SATA SSD in any desktop or laptop. However, it is optimized for NAS workloads, so it also performs well in general consumer use.
