Ignoring the TRIM issue for a moment . . . You're probably best off saving SSD storage for cases where you have lots of reads and little to no write activity, unless you enjoy buying new SSDs a lot. Actually, let's not ignore TRIM; the work-around for lack of TRIM support on some drives is a "garbage collection" routine that exacerbates the problem of having to replace your SSDs more often if you do a lot of writes. I guess I would only use SSDs on servers in the same cases where I would let myself be talked into using MySQL -- cases where you just treat it pretty much like a read-only data store, and do not have to (safely) add or change data stored there most of the time. -- Chad Perrin [ original content licensed OWL: http://owl.apotheon.org ]
