I have a Mac Pro (3,1) now but will be upgrading to a Haswell iMac or new Mac Pro. That means I'll be in the market for an external storage device. I thought I'd just get a JBOD enclosure and put my 2x 4 TB HDDs in there along with the 480 GB SSD, all of which are currently inside of my Mac Pro. Alas, it seems that's easier said than done. I've been trying to find a USB 3.0 or TB JBOD enclosure, and haven't been particulary successful. I've read that most USB 3.0 enclosures use a chipset that simply doesn't work well with OS X. DataTale has a TB enclosure that can be used in JBOD mode, and it does seem to get good reviews, so perhaps that's my best bet. But, I'm somewhat concerned with noise. (Will the DataTale be louder than my current Mac Pro? Equivalent? Quieter?) That got me thinking about NAS and stashing the drive in a corner somewhere. Unfortunately I know little about NAS options and intracacies of RAID. I need whatever device I get to double as storage and backup, so I guess I'd need to use RAID 5 if I get an NAS device? I've looked at the LaCie Big and R4, but they come with drives. I have 2 perfectly good 4 TB HDDs and a 480 GB SSD that I'd like to keep using. What are my options here? What's the best choice in this situation?
