Largest native scsi 2.5" drives I've seen were 2GB Toshiba-(IIRC) and they also made a 1GB model. More common were the Toshiba 800MB drives. I've no idea how fast are the 1GB and 2GB drives as I've not owned either, but the 800MB ain't no speed demon. The most common 'large' drive is the IBM 540MB, available from Apple as OEM shipped in the PB5xx, and from the aftermarket as well. Damn expensive at the time too, my memory is foggy, but I recall a $1000 area price. Apple did sell the 1GB IDE-converted-to-SCSI drive as an upgrade for PBs 5xx, though I have no idea if those actually shipped inside those 'Books from the factory. That drive was based on an IBM 12.5mm 1GB ATA mechanism and the ADTX IDE-SCSI converter. That converter has an ~8GB drive size limit (larger can be used but only 8 are seen) and is dog-slow. My tests in a 2300c and a 540c with 2, 4, 6, 8 and 10GB drives showed max transfer rates under 500k/s, roughly similar to the IBM 540 and the Tosh 800 (~550K/s.) The Century adapter (32GB size limit) was much faster, with throughput ~ 1.2 MB/s with any of the above ATA drives. For comparison, any 2GB or larger ATA drive I tried on a 2300c's IDE bus showed roughly double that throughput. No PB scsi bus is very fast, so I'm not sure how fast the Century adapter/large ATA drive combo will be on a Fast (or Ultra) -scsi bus. When I do test it I'll mention the results here.

I've only ever seen the Caldrives item at the US$150 price so was excited to see the $99 mention. Perhaps 'twas a sale or special or suchlike? The OP needs a larger drive for their PB1xx, and I think a 240 or 320mb unit ought to serve well and shouldn't cost too much on eBay. Important thing with these old drives is to purchase either _very_ cheaply or get at least a no-DOA warranty from the seller. Dan K -- PowerBooks is sponsored by <http://lowendmac.com/> and...
