Cons: not 12tb only 8.18tb slow to copy and has a problem at startup I have to unplug the usb and plug it back in , only has one usb plug and this isnt good enough for me because I would like to back up other devices on it instead of unplugged this all the time , in the end not a worth while buy , and kinda high for what you get .
Summary: This device comes with seven RAID modes and importantly it does not require any RAID software. And this device is pre-formatted for RAID 0. Changing the RAID configuration was not very easy though. But the 7200 rpm is really cool and that's the main reason I bought it! Moreover it is not noisy. Four connection interfaces makes it more user friendly. But it is noisier than expected. I wonder if this is a problem with this particular device.
Summary: I bought this array primarily based on it's design and claims of super quiet operation. Performance was good and easy to set up (though figuring out how to switch the raid levels took me a bit - I kept pushing the "button" on the back instead of using the tiny little Lacie key provided). However I'm mainly posting this to reflect my disappointment in the sound levels. I have a mac pro with a 4870 video card and 4 hard drives inside.
