Speed difference between IDE and SATA???

Have just got a Seagate 7200.10 320GB hard drive off the infamous auction site. It was advertised as SATA 2 interface but when it arrived it was actually the IDE ATA 100 version.

I have e-mailed the seller and am awaiting his reply over what to do next but in the meantime I was after an answer to the following.

I am wondering what noticeable speed difference there would be between the IDE and the SATA version of the drive in real world conditions.
The ide version is only ATA 100 but as the drive itself in any version will only support sustained transfer rates of 78 mbps (from the seagate website) then surely the SATA version is wasted unles you are raiding them to make the most of the higher transfer rates.

I am guessing burst transfer rates would be higher, but how often do you really get high burst rates sustained for a length of time whereby they would actually swamp the ATA 100 standard, when only one drive is connected.

I am hoping that the speed benefit of perpendicular storage will outweigh the lack of outright interface speed.

Thanks in advance for any help or advice anyone can give.
