Okay, I've got my the Promise Pegasus 4-drive array plugged into my tiny, paper-thin MacBook Air. I 've got 2TB of photos on the PP drive, a combination of NEF files and some gigantic TIFF's from the 48-bit scanning I've been doing to archive my Kodachromes of early China. Those familiar with Adobe Lightroom know that it takes time to load, and it can take time to browse through your workflow even on a fast computer with a fast hard drive. Say good-bye to all that. Lightroom has become light fast. It loads instantaneously (thanks to the solid state drives on my MacBook Air) and workflow is instantaneous as well. It's such a pleasure to edit real-time. Sure it takes about 0.5 seconds to load the previews from a 40 GB shoot. Gosh, what am I going to do with all that time! Photo editing will never be the same.
