Question to some of the storage pros Options

[Harkonnen]

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.

There's no reason the Green Power drives wont work in RAID.

You've got to ask yourself the question.... do you care if you lose the data?

If the answer is yes, then I'd either run two of the drives in RAID 1 + 2 drives not in RAID, or run them all in 5. If the answer is no, then I'd just run them all either in JBOD or no RAID at all.

Personally, I only have ~15GB of data I don't want to lose. And even then, if I lost it, it'd just be "*sigh* Well, there's 15GB of shit I don't have to backup. And years of emails I'll never actually look at again."
