Moot statement. ATA100 is the fastest the 33 MHz PCI bus can carry data.
Got some bridges for sale.

I know I can have 2 hard drives on the same cable, but can one of them be
ATA150 when the other one is ATA100? Also, will the ATA150 suffer
performance if it is on the same cable as an ATA100?
Thank you!

Maybe I am behind the times (as I usually am on many things) but is there a
"ATA150" ? I thought the highest was ATA133. Or maybe I am plain mistaken.

Newegg is selling several drives that have ATA150. If ATA 150 came out after
100, is 100 really the fastest?

Sounds like you might be confusing PATA and SATA. SATA, BTW, only allows
one drive per cable, I believe.

For an SATA-150 hard drive you'll need a system with a motherboard that has a
Serial ATA connector on it, or a Serial ATA host adapter and available PCI
slot in which to install the adapter.

Not only that, drives don't spit out 100 megabytes a second anyway -
mayve a quarter of that sustained for 7200 RPM drives, and the issue is
still moot. ;-)

For such a moot issue, alot of people sure responded. And if the drives
don't spit out more than 100mb per sec, I guess NewEgg better change their
descriptions of the drives.

Thanks for the info about the adapter and pci.

ATA 100 is an IDE (PATA) type connection
ATA 150 is a Serial ATA (SATA) type of connections.
Therefore, these two type of drives do not "directly" connect since the SATA
is a different cable that the IDE (PATA) type. If you were to locate a IDE
to SATA drive adapter, then the speeds will by the decided by the IDE channel
port on the motherboard.

Probably due to general ignorance on how everything goes together.
Is Newegg saying they can sustain 100 megabytes (should be MB, not mb) a
second? If so, that's false advertising. But it looks like all they're
doing is listing the interface speeds, as are the HD manufacturers.
If you go to Western Digital's site, here's the real info (I own one of
these drives, BTW):
Transfer rates:
Buffer to host (serial ATA) 150 Megabytes/sec
Buffer to disk 748 MegaBITS/sec
The "buffer to host" is really meaningless - that's just stating SATA
speed.
What's sad is that they don't list sustained throughput off the disk
itself, but it winds up averaging about 20 megabytes a second. Still
doesn't come close to a 150 megabytes/sec interface, which was my point
to begin with.
If you go look at Maxtor drives, they state "External data transfer
rate", which is the speed of the interfaces. It's a sick game the HD
manufactrers are doing. Seagate and Hitachi do the same thing. One can't
get information on how fast data comes off the disk. All are happy to
list interface speeds, though.
The bottom line is that it doesn't bloody matter how fast the interface
is if the disk can't sustain the speed of the interface.

Apparently you're talking about SATA. With this type of connection you
can only have one drive per cable. This is a totally different
interface from IDE. You'll also need to either have two SATA
connectors on your motherboard, or you'll have to get an adapter card
to handle them.
