It can also be used with a SATA -> IDE/ATA adaptor, that would make it appear to the OS as a P-ATA EIDE drive. http://eshop.macsales.com/shop/SSD/OWC/Mercury_Extreme_Pro/Legacy_Edition "Add a technological supercharger to your existing Mac or PC with the OWC Mercury EXTREME Pro Legacy Edition SSD. Thanks to the special PATA adapter included , it’s the fastest, most reliable IDE/ATA mechanism available to breathe lightning fast performance into that trusty machine and extend its usefulness. Includes IDE/ATA adapter for use in 3.5" IDE/ATA desktop drive bays. With PATA adapter removed, SATA I (1.5Gb/s) and SATA II (3.0Gb/s) interface supported, SATA 2.6 Compliant." So I could use this in a desktop as an EIDE ATA 133Mbs drive with the PATA adaptor, or as a SATA II desktop drive, or in a laptop as a SATA drive. The only thing I don't like is the fact that it's a MLC SSD. I'd much rather find a SLC drive, due to the x10 reliability factor. The SATA -> EIDE drive adaptors are on ebay cheap. I think this is a 2-way adapter; SATA -> PATA or vice versa. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=320645765177&ssPageName=STRK:MESINDXX:IT The other option is to throw in a PCI(e) SATA controller card, and run the SSD as a native SATA II drive in a legacy IDE desktop.
