Is it possible (and easy) to make a NAS with harddrives for storage and an SSD for cache? I don't have any data that I use daily or even weekly, so I don't want the drives spinning needlessly 24/7, and I think an SSD cache would stop having to spin them up most of the time.

For instance, most reads from a media NAS will probably be biased towards both newly written files, and sequentially (next episode). This is a use case CPU cache usually deals with transparently when reading from RAM.

Yes. You can use dm-cache.

Thanks. I looked it up and it seems that lvmcache uses dm-cache and is easier to use, I guess putting that in front of some kind of RAID volume could be a good solution.
