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.
Summary: This is one of the most affordable arrays with RAID 5 capability and is very quiet. Be aware that if it is formatted as RAID 5 the capacity drops to just over 4 gigs because there are only 4 drives in the array. I had a data corruption issue which mimicked the failure of 2 drives and forced me to reformat the array and lose a lot of data. Tech support was very helpful but hard to reach- the did not answer their phone and took a day to answer email.
Pros: Attractive Design, Compact, Good value, Quiet, RAID protection
