Last year I blogged about the amount of writes performed by workstations I run. The most was 128G in a day for atypical use (torrent download and filesystem balance) and the most for typical use was 24G in a day. If the SSDs I'm using are only capable of 61TB of writes then that would be 7 years of typical use or 1.3 years of atypical use before they have problems.
What kind of lame SSD can only cope with 60TB of writes? By all accounts it sounds like you should get far, far more than that out of the decent ones! See previous post linking to people getting a couple of petabytes per drive :) True, not all will go that far, but in the endurance test that seemed the most thorough, even the earliest-to-die drive made it to 750TB. (And that was an Intel that had a set lifespan; it would probably have gone on a lot further otherwise) T
