Mirrored volume still visible when hot-swapping
MacNN has taken a closer look at iStoragePro's Dock View RAID-iT2DockV. The RAID 0/1 box pairs two 3.5in hard disks with eSATA, FireWire800 -- and 400 -- and USB 2.0 interfaces. The drive offers hot-swap capabilities while still active on the Mac's desktop, allowing for changes to be made to the volume during a disk swap -- although volume rebuilding slows dramatically with drive access by the Mac.
In testing, RAID rebuilds worked out to about 5GB/minute and standard data transfers reached 56MB/second -- both mirrored and striped -- on FireWire 800, which may have been limited by the source. Fan noise was a slight problem, as are the manuals. A pair of 1TB drives costs $490 and a pair of 2TB drives is $695.
