Hey chaps, here's my deal: I'm looking for a 4 or 5-bay RAID. Thunderbolt would be great, but as I'm using it with an old Mac Pro another attachment method is necessary at this point. I'm currently the owner of a 16TB 4Big Quadra FW800/USB3, but sadly the purchase has soured me on Lacie: the unit produced an abnormal amount of noise for months, which I finally decided had to be a defect and had shipped off for a RMA; I received the device back three days ago but as of yesterday the unit cannot be powered up, so i think I'm going to wash my hands of it. I think I'd still prefer DAS. Given the horrors I've faced trying to get our host of Drobo NAS to appear and mount on the computers at work, I'm hesitant to go with that brand. Final consideration: being able to buy the unit without drives is a plus. Any suggestions?
