I own such a device, with 64M of storage. The ATTO "Silicon Disk II" is a 68-pin SCSI device, delivering 50MB/sec transfer rates on my Initio MilesII UltraSCSI PCI controller. It is from the late 80s early 90s (NuBus Mac era), and is no longer manufactured by ATTO. Mechanical LVD devices are faster than this. The MilesII can deliver up to 80MB theoretically with differential hard drives, although I've experienced only ~60MB/sec on my 9500. >Probably cost more than just going out 'n' buying a machine that could hold >a Gig of RAM. Yes. The proprietary expansion RAM is obscenely expensive, at $1500 per 256M card (slots for two cards), priced March 2001. ATTO offered a 10% discount, but I remained un-tempted. -- m. g. gadzikowski | [EMAIL PROTECTED] -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
