I was thinking the same thing, setting up a new server with ssds instead of hdds as I currently have
and was wondering what the thoughts are in regards to using raid (it would probably be a dell R710 card -
any comments on these as they are new). I was planning on using intel 320s as the 710s are a little too
pricey at the moment and we aren't massively heavy on the writes (but can revisit this in the next
6months/year if required). I was thinking raid 10 as I've done with the hdds, but not sure if this is the
best choice for ssds, given wear level and firmware is likely to be the same, I'd expect concurrent
failure on a stipe. Therefore I'd imagine using an alternate mfr/drive for the mirrors is a better bet?
What are peoples thoughts on using a non enterprise drive for this - the choice of enterprise drives is limited :(
I was thinking if we have sudden power failure then mark the consumer drive as bad and rebuild it from the other one,
or is this highly risky?
Does any one do anything different?
Thanks
John
