ASUS P4SD-LA Question

I have a HP m380n Desktop that I have owned since 12/23/2003 and still going strong, very few problems with hardware.
It has ASUS P4SD-LA mobo Pentuim 4 3.0 GHZ
I have upgraded w/4GB Ram
320 GB HD as Primary and 160 GB as Secondary on IDE.
I am wanting to add a larger 500 GB HD using SATA (2 on MOBO) and manual states each connector supports 1 ATA - 150 Drive
Question:
What type of drive is available for this setup?
I have researched and have become bewildered due to not keeping up with new terms and old systems.

First post on major geeks but have used Major Geeks several times to find help and answers, much info. Good Site

 

Hello,
ATA - 150 is basically a SATA drive. In more detail ATA-150 (1.5 Gbit/s) is the maximum transfer rate of a SATA device on your motherboard. That would be considered a SATA 1 drive. Most SATA hard drives now have a 3 Gbit/s transfer rate (SATA 2). Some of these drives have a jumber setting so they are forced down to a ATA-150 or SATA 1.

 

Thanks for the clear answer explaining the difference in SATA descriptions, this has helped very much.
