Did you know you can improve the overall performance of your network-attached storage (NAS) by installing an SSD? This isn’t to expand the storage capacity of the NAS but to allow the OS to use the drive to cache frequently accessed data. It’s a similar principle to RAM but albeit much slower. Still, using SSD caching could improve performance, especially when relying on slower SATA mechanical hard drives. I’ll go into SSD caching, how to improve your NAS with an old SSD, and whether you actually need to do so.
