To get a picture of the performance of these storage products, we resorted to a copy tool instead a relying on a classic backup program. As a rule, backup programs are used with data compression. This does not always make sense when using hard drives, as one of their benefits should after all be direct access to the saved data. Running compression algorithms also places a high load on the system, so the storage device interface is no longer the bottleneck.
