So,found this product for relatively decent price. http://www.buffalotech.com/products/external-drives/drivestation/drivestation-quattro/ 2.0Tb of space, or 1.5 in Raid 5. Self-rep system and os-x supported. The quirk is that is has a free eSATA pci card with it. But nowhere could I find if it is supported in OS X too,or only on the PC side. If not,then you´d be bound to use it in USB2 mode. Wich would be a that big bitch,because it would be used as a external storage/backup for photos and video. But for the price,650€,it is about the cheapest thing with raid 5 that I have found. The intells ss4400-4 costs about the same without the drives! AND is a bitch to setup because you need a pc for that. So. Yay or nay? Edit : Would it be possible to route this device via the one of the free sata slots on the mobo? eSATA connectors are different than normal sata´s eh? But do you have a eSATA-to-SATA connectors? How would the MP see this device then?
