More than expected
I got this as a backup drive to my Glyph GT 050Q desktop, and it was even smaller than I thought it would be. More importantly, it turned out to be quiet enough to run while recording, which my desktop Glyph is not. (Though sometimes I forget to turn it off anyway!)
So it turned out to be a great way to avoid both recording to the internal hard drive and surface noise at the same time. Also saves needed desk space for other gear. Automatic sync feature also very useful.
