On the intel drives, its available via SMART. Plenty of hits on how to read the data from google. Sandforce drives
probablyhave it exposed via SMART as well.
I have had over 50 X25-M's (80GB G1's) in production for 22 months that write ~100GB a day and SMART reports they have
78%of their write cycles left. Plus, when it dies from usage it supposedly enters a read-only state. (these only have
recoverabledata so data loss on power failure is not a concern for me).
So if Sandforce has low write amplification like Intel (they claim to be better) longevity should be fine.
