Is the 710 series too costly for your deployment ?
I ask because that would be the obvious choice for a database (much
better write endurance than any of the drives above, and less likely to
suffer from firmware bugs or unpleasant GC behavior).
We've been running them in production for a few months with zero
problems and great performance.
The price on the 710's tends to vary on whether they're in stock :
NewEgg is currently showing $1100 for the 300G drive, but no stock.
