How tons unyielding drive can you connect within one computer?

Usually a computer can support up to 4 devices close to Hard Drives or CD/DVD Drives without any adaptors. Extra, you can include a RAID card with two more slots for two extra tricky drives on each, so you will hold FOUR more units. The price for the card is around $39.00 and so on. And don't forget an extra power source.
Depends on how plentiful open bay inside the computer, plus you can hook some up externally though a usb port. How many do you want hooked up?
Hi, you can put up to 16 firm drives on a single scuzzie drive, and on the main port 2 tricky drives.
I had connected 3 not easy drive, I think within is no limit.
