Sensible places to use SSD for Redis: RDB persistence, AOF persistence.
Not sensible places to use SSD: swapfiles.
Swapping to SSD will also trash your SSD, because you are continually rewriting it.
- sp332 14y agoWriting to your SSD will not "trash" it. Even in 2008, Intel drives were rated for 100GB/day for 5 solid years. http://www.anandtech.com/show/2614/4 http://www.anandtech.com/show/2614/4 And controllers have only gotten smarter since then. Edit: The physical tech has also improved since then with "high-endurance MLC" cells. http://www.anandtech.com/show/5518/a-look-at-enterprise-performance-of-intel-ssds/6 http://www.anandtech.com/show/5518/a-look-at-enterprise-perf...
- nbevans 14y agoActually SSDs are the best place for a swap file. 4K random reads and writes. If a few random 4K writes is enough to make you worry about your SSD failing then you bought the wrong SSD (i.e. a non Intel or Samsung one).
