With such big disks you ought to at least use a USB3 interface. USB2 and 3TB? If you were to try and fill it at max theoretical USB2 speed, that would take about 2 weeks :-o
USB 2 and large drives can take so long to do things that it is actually painful. I used to set mine to do their thing overnight.
I switched to USB 3 for a 1tb drive and eSATA for a 500 gig external drive. What a difference. The USB 3 requred a ePCI card but the motherboard already had an eSATA plug-in.
I agree with Gerti that large external disks should only be offered with USB 3, or better, interfaces.
Of course, you could finish two or three woodworking projects while you wait for the USB 2 drives to do their thing.
This may end up as removable media. And yes it is for home. But remember my home setup is far from typical... My initial intent was to hang it off of my router as a router attached NAS drive, split into /opt (for apps), swap, and /data partitions, then run a DNLA server from the router. I wanted to be able to run into the router from my phone, or laptop from wherever via the OpenVPN, and run my media right off the router. I have no intent to fill it all immediately, and honestly 2TB is enough. But Amazon had the 3TB unit for $10.00 more...
Sadly with the current firmware on the router (DD-WRT 2.4) the largest drive I can use is 2TB... I have a 2TB internal drive in my Windows box, and a spare USB 2.0 / SATA II enclosure that I might just press into service. The 3TB USB box can get tacked onto my server as a backup unit. The Win7 box really doesn't need 2, 2TB disks anyway...
Even at USB 2 speeds though. Partitioning, and formatting the filesystems on 3TB of disk took a total of 2 hours. All things considered, not horrid...
I've been wanting to upgrade my backup to a RAID system, so I don't have to worry about a drive crapping out and losing it for good. I just found an enclosure on Amazon that I'm thinking about getting. Only thing would be to buy two 3 TB drives to replace the 1TB and 2TB drives I have now.
