My main gripe with this drive is the speed, it’s nowhere close to being gigabit speeds, I’m only really seeing speeds comparable to 10Mb ethernet connection! I’ve tried it connected to a windows machine and it wasn’t really any better so I don’t think it’s a Mac issue.
I’ve actually talked to WD support a fair bit about it, I was told the drive actually uses a file system called ‘ReiserFS’ -
http://en.wikipedia.org/wiki/ReiserFS - so it should be a very good system. But the write speeds make it useless for me in a work situation. I’ve simply taken it home to use as a NAS drive for home use and I’ve got a My Book Pro Edition on it’s way for use at work.
The WD support seemed to be aware of the issues with the drive, I’m hoping they bring out a firmware update for it that improves it’s performance.
