I got to thinking a bit. It would be really cool to have a external storage unit for HDs that would be self powered, noise insulated and could connect to your main PC.
There are a number of off the shelf products that you can buy that are meant for this purpose such as large firewire/usb harddrives. There are a number of NAS. I saw a ad on ebay for a SCSI storage unit (
here). Many are really expensive.
I was wondering if you guys have any thoughts on building your own. Conceivably you could buy a cheap PC case, add the necessary PS, add your HDs but what interface would you use? What kind of card/device would you use for the interface? If you went SCSI, it seems pretty straight forward but unfortunately the drives are cost prohibitive. The solution is quite elegant though because SCSI drives are really fast and don't take up a lot of system resources.
How would you implement a Firewire or USB 2.0 solution? I have no idea. Is it just best to buy an off the shelf external firewire/usb drive?
Anyway, I was hoping to start a discussion on some cost effective ways of implementing large external drives that would minimize the resources (CPU time, memory, PS draw, etc) on the main system. Solutions that allow the storage unit to be placed relatively far away from the PCs would be even better as they could placed somewhere where the noise is not a factor.
Cost is a factor here, so please keep that in mind. Also flexibility would be nice. My idea for a random case that can hold drives for instance would be nice because one could always buy more HDs in the future to upgrade the capacity.
