Hello, I would like to ask somethings about this bit of hardware if someone has one they will most likely be the most help 1) Is the 0TB ones worth the cost (ill be getting my own drives) for the hardware raid? 2) How well made is the overall system does the hardware raid work well? 3) if i use it in raid 1+0 or raid 5 if a drive fails do i have to power down the box to replace the drive or is it hotswap? 4) Does Macsales (OWC) ship to Australia and how does warranty work? 5) Can you also use this with no raid? 6) Say if i turn the Mercury Elite-AL Pro Qx2 off it will kill the data if its in raid? when it if does not when i turn it back on does it have to rebuild the array? and how long does that take? Also what do you think of this over all?
