My SATA 3G SSD went bad. Basically it wouldn't boot, then I erased it using Secure Erase, so I could reinstall the OS, now my Mac Pro won't even get past the white screen with the SSD connected. Basically if I connect any other drive, my computer boots up fine. That said, I'm going to warranty SSD, but in the meantime I'm looking at other upgrade options. One of these is the new OWC Mercury Accelsior PCI Express SSD. Prices aren't too bad and speeds look pretty good. I have a free PCIe slot to use this with. Anyone try this?
