I'm currently running my boot drive externally connected via eSATA on a OWC Mercury Elite-AL Pro Quad (Oxford 924) Interface eSATA, enclosure with WD 640Gb 32MB cache drive. All 4 bays are occupied with storage drives and I was wondering if I could buy 2 Intel SSD X25-M 80GB, another OWC enclosure and set them up in a RAID as my boot drive? Or is there a better set up for SSD externally?
