You mean ATA/66 ? if so, ATA/66, 100 and 133 are just the speeds of your bus. You don't really need higher than ATA/66 because even the fastest laptop drives don't saturate the 66 bus IIRC. ATA-66/100/133 exist for both 2,5 and 3,5" harddrives.

I don't think i mean ata66 becuse i know ata 66/100/133 lol. I am confused becuase then y does laptops use ata5 and ata6 i know there isnt a ata 55. Does the powerBook use ata 100 on the specs sheet it said it did. Im thinking of getting the new Hitachi @ 7200 8mb cache but if ata100 is faster then i dont know. i may leave it the same. stalk. apples web site says ata 100 but i havent seen ata 100 for a 2.5 inch hd. http://www.hgst.com/hdd/travel/tr7k60.htm

Anyone can look at the frontpage of Macnn to see the new firewire drive they wrote about. It says "A single bridge controller supports two drives with full ATA-6 speeds." I think thats yoyoman is referring to.

ATA-1 through ATA-6 are the formal names for the currently ratified ATA standards.

ATA/33/66/100/133 are informal names for the various speeds of different ATA buses. (Often these are used when faster buses were installed on a drive or motherboard before the actual standard was ratified! Such is the case with ATA/133, which has not yet been ratified into ATA-7.)

ATA-6 (ATA/100) notebook drives exist, but the same truth applies to them as on desktops: no drive in existance is fast enough to singlehandedly saturate an ATA/66 bus, much less an ATA/100 or ATA/133 bus.

All Apple PowerBooks (and iBooks) ever made use 2.5" drives, by the way. (The only battery-powered computer Apple ever made that used anything else was the Mac Portable in 1989, which used a standard desktop 3.5" drive.)

Pretty much a standard 3.5" drive, except the connector was different.

Which powerbook are you referring to?
the 12"Albook and the 17"Albook come with ata 100, and the 15"Tibook comes with ata 66.

12" specs here

15" specs here

17' specs here

Furthermore I checked here , and found out that ata 5 = ata 66 and ata 6 = ata 100.

And yes all powerbooks beside the one tooki mentioned come with 2.5 drives


aloha

yoyoman, the size of the harddrive is not tied to the speed of the ATA-bus

I don't know if this would be the place to post this or not... but I guess since the original poster's question has been answered...

I had a dream about you the other night. Nothing special, but I dreamed you lived in San Diego. I woke up and checked MacNN only to find out you don't. But there you have it.
