Hi, I'm in the market for a raid external hard drive solution. I do not need a NAS external drive. I am a photographer looking to store my photos on a large drive that has raid 5 or 10. I came across the OWC Mercury Elite-AL Pro Qx2 and would like your feedback on this unit. Should I go with this setup or something else? I am looking to get the 8TB version setup on eSata with my iMac 27 modded with eSata. http://eshop.macsales.com/item/Other World Computing/MEQX2T8.0S/ Please let me know if this is a good solution to go with or should I go with a different brand and setup?
