Does the job
How can you really access a hard drive. The fact that it's got two thunderbolt ports is a good feature as the thunderbolt system is designed to be daisy chained. I'm using it for back up only in the RAID 0 mode (two drives mirrored). The only issue I have (and the reason I gave it only 4.5) is that it does make noise. If you're recording in a small quiet space and have it running, you will hear it, so you'll definitely want to isolate it.
