Pros: If you need reliability, this is the one to get. The 5 year warranty says it all, WD has a higher opinion of the Black Series than the other colors. Spend the few extra dollars and get the better drive; it's your data.
Summary: The black series continues to be the best HDD you can buy. They are reliable and fast and now the sizes are getting huge. Prices continue to plummet on multi TB drives so why not buy the best. This is maybe my 4th or 5th WD Black.
Summary: I bought 2 of these drives back in 2010. Well, the SATA2 versions to be honest. At first, I bought them to create a RAID1 volume on my motherboard, but the RAID software was so glitchy that I decided to drop the ball on RAID1. About 1 1/2 year after I bought them, one of the drive was having bad sectors issues. Because these drives are 5 years warranty, I contacted WD and got my RMA very quickly.
Pros: Very good performances, Quiet, 5 years warranty
