I use a new MacPro 12core with Snow Leopard. Altoghether, I use about 15 terabytes of data spread across the 3 Drobo devices and am looking to replace external drives since the ones I have are not working with my new MacPro in 64bit mode. I currently have external storage devices by DataRobotics - 2 DroboPro and 1 DroboElite. I bought the new MacPro 2 months ago and have been having problems with the Drobo devices disconnecting constantly. After a lot of diagnostics including Apple replacing the logic board in my MacPro, it was identified that the issue was with the iSCSI initiator that DataRobotics uses. It is not 64bit kernal compatible and as a result, the drives disconnect randomly especially when moving data from one external drive to the other. I am forced to boot the MacPro in 32bit kernel mode for the drives to work properly. DataRobotics is not committing to fixing the 64bit kernel issue so I'm now looking to replace this technology. I found some interesting technology by Netgear and was considering buying their product, however, I had the worst experience ever with dealing with pre-sales & technical support department, after dealing with 4 different individuals, I concluded that they have no clue about their own products, the staff is so junior, it's as if I called a completely different company when talking about their own product. I am therefore going to stay away from that company. Would anybody be able to recommend a reliable company with proper technical support that will work well with a MacPro running in 64bit mode? My parameters are: - MacPro compatible - Snow Leopard 64bit kernel mode compatibility - reliable and fast - good technical support (if required) - relatively quiet (I have my computer and drives in a studio where I bring clients) - about 15 terabytes of storage space (It's OK if it's in a single external box or more than 1). Any input you could provide would be appreciated.
