except, those high end enterprise products ARE write-safe while most
SATA SSD's aren't. The enterprise SSD's like STEC are engineered for
much higher write cycle life times. the whole storage infrastructure
has several more 9's on its reliability. those extra 9's don't come
cheap. and if [Bigname Vendor] sells you a system with storage
controller X and drives Y, you can generally assume they've been tested
together. they are also selling their service and support, for better
or worse.
SAS has better IO concurrency than SATA, and SAS drives are dual path,
which means you can have redundant storage channels and cabling, even if
you're doing JBOD..
