I am looking for an external hard drive solution in the 2 TB range. I have researched and found 3 candidates, the Verbatim 2TB USB / eSATA 2-Disk RAID Desktop Hard Drive, LaCie 2big Quadra, and the Western Digital My Book Studio II - 2 TB. This drive will be used primarily for data storage and portability between work and home. I am looking at running in a RAID 1 configuration, what would be the top choice out of these drives?
