I just bought the Western Digital Red 3TB hard drive for my Dell XPS 435t/9000 as a second drive for media. I just realized that the red is "designed" for NAS systems. Can I use this as a "regular" hard drive? If yes, am I losing anything over another similarly situated "regular" hard drive? I can return it quite easily (it is still in the box).
They work fine as a regular HDD
difference between normal and RED (nas) drives is Price and some Hardware level error correction stuff for raid solution
RED drives also run at 5400 RPM, have 3 year warranty and lower MTBF ratings from the enterprise drives (7200 RPM, 5 year warranty and higher MTBFs). Enterprise discs are more expensive but aside from other features, the increased speed and better warranty should make-up for their increased cost and they also include the time-limited error recovery (TLER) feature which is included in the RED drives.
