Hi all, New around the forums, so hello first of all. I'm coming to you with a question about how to best upgrade my Mac Pro to take advantage of the magic of SSDs. It's a 2008 Mac Pro (Harpertown generation) and I've got all the SATA slots filled up with HDDs that I'd rather leave as they are. I'm a composer and I work with vast sample libraries, and splitting them across multiple drives is the best solution for optimal streaming performance. I may need to add an SSD into the rig in the near future though, and I'm hearing that models now exist that plug into PCI slots instead of SATA ones (which would be terrific since it removes the SATA bottleneck and lets me keep my existing drives in place). If such a thing would be possible, can anyone recommend some of the better options out there and/or give me some feedback on how they perform in terms of speed and reliability vs. SATA-based SSDs? Will they work with my Mac Pro? I would need to fit a total of ~460GB of data, so I assume I'll probably need two of these rather than one (or else risk exploding my bank account). Anyway, so that's the basic situation...if you've got some insight to share, I would love to hear it. Thank you!
