Both IDE and SATA are faster than the USB (even USB-3) you use to connect the external to. So it makes no difference.

Hello, I'm looking to purchase an internal hard drive for backup purposes only. Somebody mentioned that it was cheaper to buy a used internal hard drive, adapt an external enclosure, and use it as an external hard drive. Taking that into consideration, I would only assume that IDE drives are going for a lot cheaper than SATA drives due to age, speed, and technology right?. Just how big is the difference between IDE, SATA, 7200 rpm, 5400 rpm, for backup purposes only.
