I'm looking for suggestions on what to buy when it comes to a storage system for removable hard drives. It'll be used in a small office environment meaning it should be reliable, quiet, and reasonably fast.
I currently have a Proavio 4-bay rack enclosure with removable drives:
It's connected to my Mac Pro through Firewire 800 but has a few flaws: it won't accept drive bigger than 2TB, it's noisy (yes, I've changed the fans), each hard drive needs a tray to be attached and a couple of other frustrations. I also didn't end up installing it in a rack, so this time around I'm considering a "tower" of some sort. I've been looking at 5.25" backplane modules such as these from Orico:
My guess is that they don't contain any interface electronics, so I wouldn't run into a hard drive size limit as now, because that depends on the SATA bridge board I decide to use. They're also trayless meaning I can just pop in the drives. The problem however is that these modules are designed for PC cases and not stand-alone as I need (there's no such space available in my Mac Pro). Firewire (and possibly USB) would be nice, but since my Mac Pro has an eSATA interface I should be fine with just SATA.
So, are there any ready made desktop systems with those features? I'm also open for other suggestions, but being able to exchange drives is a "must have" feature I've found invaluable when making backups and whenever my drives fill up.
