I'm a photograpger with a 2.4ghz MBP. I need additional external storage for my digital files. For expandability, I've been looking at 5 bay external drive case (by AMS - Venus T5). AMS tells me that I must be using an PCI Express card running with SIL 3132 Chipset. I've looked at the Rosewille RC-605 that is running that chipset. However, when searching the forums, I'm finding numerous issues with this chipset. Am I on a dangerous/troublesome path? I wondering if I should just go with a dual drive case from OWC (or from AMS) that is FW800 for now. I don't really need the added speed of esata; this is primarily for image backup. Appreciate any insights (including and enclosure comments).
