In addition to having a weak endurance rating, the S3500 is also quite slow. But given Intel's rather good track record here, I would expect (not having used it myself) that it does meet its specs throughout its lifetime. There are still a lot of consumer-grade devices out there that don't, and I'd expect them to work poorly in a zpool or anywhere else. > WD3000FYYZ or the smaller model, so pretty standard SATA3 enterprise drive. > It's a passive direct connect backplane, so I'm not worried about SAS.

The only possible exception is the Black. But why take chances? HGST makes better drives that aren't terribly expensive. I'm not sure I love the S3500, but I'd probably choose it over a WD spinner if those were the only two choices. > While we are talking about endurance, this was interesting as well: > http://blog.backblaze.com/2014/01/21/what-hard-drive-should-i-buy/ <shameless plug> You may have missed my response to that.
