then you did something wrong, perhaps using a shitty raid controller or
it was bottlenecked with a slow link, such as usb 2.
raid 0 definitely speeds things up, but doubles the risk of failure.

the other issue is that the reliability of modern drives virtually
guarantees a failure on rebuild, particularly with raid 5.
