You can get spinning disks and SSDs with an MTBF of 1.5 million hours, so they should last about 170 years ... An SSD that doesn't get much written to could last a lot longer because it doesn't have the mechanical wear --- they might have something else that fails, though. I'll consider them if my current boot disks fail -----Original Message----- Well, I've been there. A couple of years ago I did a fresh install on a 32G ssd, and that worked fine for about a year. However, (probably because doing the install in the small hours of the night) I forgot to disable swap. So after upgrading, I found that it started raining disk-errors. Ruled out any mem-problems, and started testing. The amount of disk-blocks that could be used reliable dropped very quick. In three years time from "new" towards "brick" So, ssd's are fast&reliable but only for write-seldom purposes. - keep as many as possible filesystems RO (atime off) or in mem - do logging remote - bulk data / often changing parts, like homes or mail on HDD.
