You will only be able to run up to 128 devices on your USB bus. Each of the 4 (or however may backside/frontside USB ports you have) ports are all connected to one controller on your motherboard. The extra ports just come from an internal hub (which is also on the board). So, you can have up to 128 devices hooked up to your USB controller (128 total). However, because USB cannot provide unlimited amounts of power, most of the hubs providing these 124 (minus the 4 you already have) extra ports would have to be powered to prevent your USB bus from being overloaded. So, if you'd like to have 128 external hard drives talking to you computer through one 480Mb/s bus (actually slower because of USBs master/slave design, which is unlike IEEE1394/firewire) then do so.

You can connect up to 32 devices on each usb port, as long as they have their own power source. You can also connect hard drives through your network card which has no limits of number.

When USB first came out i remember reading an article that stated it could run about 70 items from one USB port, it may depend on the items themselves but i reckon you could probably run a few hard drives from it.

Usually it's 128 devices per usb port, from my understanding...

as long as you use one at the time on the same usb port not a problem..

The limit is I think 127 usb devices per controller. You are 'most likely' safe unless you are hosting Yahoo ;)

Theoretically USB ports (if you chain them to have enough physical ports...) can have up to 127 devices.
Never tried it though.

No, just make sure you format each one and don't loose track of where your storing stuff. If your going to spend that much money on harddrives though, y don't you just get a new tower? It would be cheaper and a lot easier to keep track of where documents are saved.

2 for each IDE
7 for SCSI
unlimited for USB, at least in theory
