"Inexpensive fast SSD, but unreliable."1.5 starson by OldBlueDagger
Pros: Only $132 from CompUSA. Fast.
Cons: Failed within my first week of ownership with a random "reboot and select proper boot device" error. BIOS randomly can't see it. Came with 1.4 firmware. Look for something more reliable.
Summary: I'd steer clear of this one until the firmware is figured out. Sounds like this "reboot and select proper boot device" error is historically common with OCZ SSDs, and the Vertex 4 is no exception.
