Are the old issues fixed?
I thought I read somewhere that these models had a capacitor to keep the write cache from being lost on power outage. The X-25s were known to have issues where data was lost even if write barriers were turned on.
Even worse, when the SSDs where set in the modes to flush transactions to disk reliably the performance was about the same as a raid setup.
*As I'm writing this I've read that the 710 has "Enhanced Power Loss Data Protection" that should protect the drive from power loss. I can't wait to see this benchmarked and trialed on real database loads.
