Question using this external as Raid 1 or Raid 5

[jordan12]

I am looking at this external

http://www.newegg.com/Product/Product.aspx?Item=N82E16816132029

If I put four 1 TB drives in this and run it as Raid 1, how would that ultimately look?

Also if I chose Raid 5 instead using the same four drives, how would that work?

I know the basics of Raid, but not sure of how it would all work.

Sorry for the stupid questions

4 1 TB drives in RAID 1 would be a grand total of 1 TB of usable space..

RAID 1+0 would give you 2TB of faster space.

RAID 5 would give you 3TB of slower space.

What are you trying to accomplish? What is your goal with this product?

I am looking to try and have this only hold backup images of all of my other drives.

But I want a way to where if one drive fails, I can replace it and have the raid rebuild...But I need about 3 TB of usable space for this to work for me..
