I've decided to get this
4-bay drive enclosure or the cheaper non-raid variant.
The most cost-effective thing I can think of is to fill it with four 1.5TB WD Green power drives, running independently for a total of 6TB (5.5TB NTFS).
Or run it in RAID5 and fill it with four 1TB enterprise/raid-edition drives for extra speed and data protection. However, I've heard RAID5 isn't fool proof on rebuilds and having nearly 50% of the space seems like a huge tradeoff. (I'd need to get 1TB drives as I've heard the WD green drives don't work in RAID and I'm never buying Seagate again).
Thoughts? Any opinions would be great.
I don't really need speed so much as space and protection.
