I'm aware of no reason to do so. Typically usb 2.5" disks can be powered off the USB cable, which is much more portable than the PSU required by external USB 3.5" drives. I would guess that most drives are generally about as reliable as each other. They are inherently at risk from mechanical failure, but some succumb within weeks of purchase, others not after a decade - it's just a matter of pot luck (which is why backups are so important).
