This review is from: WD My Book Thunderbolt Duo 4TB External Dual Hard Drive Storage with RAID (Personal Computers)
Vine Customer Review of Free Product (What's this?)
This doesn't come with a Thunderbolt cable. And it only works with Thunderbolt.It shows 3.83TB for me, for whatever that is worth. You can set different RAID settings to ensure backup, but you basically cut your storage in half to do so. Uses Caviar Green drives, which are supposed to use less energy and are, I think a key feature, user replaceable.
Once you plug it in, it loads up very, very quickly. I'm getting into video editing now and its blazingly fast. It is as big as my Mac Mini.
