According to OWC, this is a SandForce Driven SSD. I added the following two lines to the list of SandForce drives in drivedb.h, and everything appears to make sense:
"OWC Mercury Electra (3G|6G) SSD|" // tested with
// OWC Mercury Electra 6G SSD
I've attached test2.txt to show what the data looks like after the above changes. Field 9 appears to be accurate, since I just got this drive yesterday, and it's been running pretty much non-stop since.
Thanks!
