You have listed both budget and enterprise class drives here and the pricing is an indicator here. I feel you need to purchase the drive that meets the data speeds you are trying to achieve. If this is not a high speed situation then you could use any of the drives. The WD Red have not been in the market place very long but I own 4 of them and haven't had a single problem. Typically if a drive doesn't fail within the first few weeks of use, they will last a long time, that goes with any manufacturer. I know my company buys the Seagate Constellation drives for server and desktop use and will likely continue to do so. I have three of those drives in my office and they have been running for 3+ years without issue.
My personal favorite is the WD Red for a home use server. If I was building a high use office server, I would not use the WD Red because they would be too slow for that environment in my opinion.
