    I'm in the market for an external drive. and am considering something like the Western Digital My Book Mirrow Edition II 1 TB:

    The drive is advertised as having a 1 TB capacity in RAID 1. What I am confused about is does the drive have 2x500 GB hard drives, which gives you 500 GB of usable space but 1 TB of total storage, or 2x1 TB, which would give you a true 1 TB capacity in a RAID setup?

    If there is someone here who owns this drive or one like it who could clarify this for me that would be great.

    That appears to have 500GB of usable space, in the 2x 500GB setup you described. I don't own one, but there is also a 1TB unraided version, with 1TB of space on a single 1TB hard drive. This version, with two hard drives, costs $11 more than that unraided version - far too little extra cost for it to contain 2 of the 1TB hard drives.

    Non-raided version for reference: http://www.buy.com/prod/western-dig...-external-hard-drive/q/loc/101/205761335.html
