Summary: A very fast drive until it died 3 days outside warranty period (warranty expired on Nov 18th, drive died on Nov 21st). Can't even access the drive now. Thought that a refurbished drive from western digital was a safe bet. Learned my lesson here; do not buy refurbished drives, even from a company that is usually very reliable.
Summary: Gambled on buying a refurb and lost. bought WD hoping a good company would still produce a good refurb but crapped out on month 7. disk check runs with no bad sectors but windows says to replaced HD. still running but a pop up to back up my files repeatedly comes up. Just waiting on the crash.
Summary: I bought this drive to clone my 750 gig (but not near full) WD Scorpio Black drive to so should the larger drive fail, I would have a plug-and-play backup clone while ordering a new (larger) drive.
Pros: Brand Name
Cons: Significantly slower than I expected for a WD Scorpio Black 7200 RPM drive.
