WD Red SA500 500GB SATA SSD
This 500GB internal solid-state drive uses SATA III 6 Gb/s connectivity and 3D NAND technology. It is built for network-attached storage systems that operate continuously. The drive targets home and business users who need reliable caching for frequently accessed files.
Sustained 24/7 caching workloads
The SSD is tested for non-stop operation and handles heavy read and write loads without throttling. Endurance ratings support constant caching duties such as multi-user databases, photo rendering and 4K or 8K video editing. Latency stays low during prolonged sessions rather than short bursts.
M.2 2280 form factor for NAS bays
The 2280 size fits standard M.2 slots inside compatible NAS enclosures. SATA interface limits peak throughput to 560 MB/s but ensures broad compatibility with existing appliances. Build quality focuses on vibration resistance and thermal stability for rack-mounted environments.

Questions about this item
Does the WD Red SA500 500GB run hot or draw much power during 24/7 NAS caching workloads?
The drive is purpose-built and tested for continuous 24/7 NAS operation, using efficient 3D NAND to maintain performance under heavy read and write loads without excessive heat.
What host interface and form-factor slot does the WD Red SA500 500GB need to operate?
It requires a SATA III 6 Gb/s interface and an M.2 2280 slot that supports SATA signalling for the drive to function.
Will the WD Red SA500 500GB work alongside older mechanical NAS drives in the same array?
Yes, it is designed as a caching tier for NAS systems, reducing latency and improving responsiveness for mixed workloads alongside existing storage.
