A few months back before RAM prices hit the roof, I decided to add a nice little perk to my NAS. Specifically, I added in SSD caching to eke out a bit more speed, because I thought my hard drives were being the bottleneck to peak performance. My NAS handles everything from file storage to applications, indexing, backups, and more. Once in a while, I might even dabble in a workload with plenty of reads and writes. An SSD cache should help with all that, right?
