Support for Apples Time Machine is not enabled by default and you cant turn it on using the LaCie Network Assistant software. To enable the feature you need to go to the browser-based Dashboard, go to Settings, and click on the little tool icon to turn on the service. Then you go back and select the volume you want to use, click on the little Protocols button, and then turn on Time Machine. Once enabled, I was able to backup my Mac to the 2Big NAS and successfully revert to versions of files backed up on the device.
In our performance tests, the 2Big NAS was an average performer, writing a 10GB file at 40.6 MBps, and reading that same file at 71.6 MBps. It was slower when handling a 10GB folder full of smaller files and folders, writing at just 12.7 MBps and reading at 34.7 MBps.
One thing I noticed was the noise made when the NAS was working. At first I thought it was a drum track playing on the radio we had quietly playing in the lab, but it turns out to be the churning sounds of files being written and read. I know its not meant to be sit on someones desktop, but youll want to consider placing this somewhere out of earshot.
Macworlds buying advice
While not the fastest NAS device weve tested, the LaCie 2Big NAS was fairly simple to use and offers nice variety of features, including remote access using a browser or the LaCie MyNAS iOS app.
