Weighing a bunch of different options for an external RAID setup I plan to use for primary/working photo storage (Lightroom/Photoshop). Looking at 2TB (effective space) solutions from a few different manufacturers, namely: G-Technology (G-SAFE) Fantom LaCie Iomega Western Digital I'm skeptical about both Iomega and Western Digital, but reviews for the units I've looked at are pretty promising. I'm also not sure about how important I should consider hot-swapping, as I'm not sure how the non hot-swappable units handle drive failure recovery. Lastly, although I'm looking currently at RAID 1 (mirrored) solutions, I'm wondering how bad the RAID 1 peformance hit is going to be vs. a RAID 0 solution and if I'd be better off grabbing a RAID 0 solution and a second drive for backup. Ultimately, are the RAID 0/RAID 1 performance differences even going to be noticed over firewire 800? Any thoughts/advice are appreciated.
