If I have a need for 4T of space for storage, is it wiser to buy 2 hard drives of 2T rather than to get one 4T drive??

Any drvie could fail at anytime, but I think it's less likely for two drives to fail at the same time.

And As a result, getting two drives of 2T should be more economic????


Does it make sense ?
 
Solution
Better to get one big drive and not have two points of possible failure. The more things in your system the greater the odds that something can go wrong. If the data is that important I recommend getting a dedicated drive to backup your files to. I do see what you are saying about two 2TB drives. You would only loose half your data if one drive went bad but any data loss sucks..

You could always if getting two drives of the same capacity, think about setting them up in a raid config.
Where the information or Data would be mirrored from one drive to the other.
It would ensure you have an exact copy of all the data of one drive to the other.
If in such an event one of the drives fails in some drastic way.
You would still retain all of the data stored.

The other plus side is by setting up a raid of two drives with identical data on both, or mirror image would be read and write transfer speeds would increase slightly.

Just a thought.
