If you’re considering purchasing an external hard drive, :Category:Benchmarks[ these benchmarks] should hopefully help clear up some questions you might have.

It has even taken a drop while it was plugged in (it disconnected from the cable even). Here are the IO metrics from the great GNU utility, dd
