USB 3 - Wow

Sonos CD ripping has become a big part of our workload, with the size of CD collections getting bigger. This week we completed a 2,000+ CD project, in Apple Lossless for someone who is installing a Sonos system as part of a major home refit. This created a 750 Gb library which was placed on a new drive.

This had to be moved onto another USB drive. When we do this I always think back to the first time I tried to load around 40 Gb onto a drive, only to find the USB port on the Dell PC was USB 1.0. It took hours, and hours, and hours. When the computer started the copy process it calculated the task would take over 25 hours. Unfortunately I couldn't dedicate that chunk of time on the PC I was using so the task had to be put on hold.

Then this morning we received a USB 3 card, a technical straw to grasp. A few minutes later the card was installed, late this afternoon I started the copy job again. This time the predicted time was down to just over 5 hours. A massive five fold improvement in elapsed times. Wow.
