What is the primary advantage of an 8 meg buffer over a 2 meg buffer and is there a noticeable performance impact especially for demanding apps like FS?? Also, what is the differances of interfaces as in ata 100, 133, 150 etc.? Will I need to check and see what my Mobo requires there? Thanks.

An 8 mb cache is much better then a 2mb cache.

BTW, fs2004 is not a demanding app in terms of hd performence. A 2 mb cache is fine and you won't feel a noticiable difference with an 8 mb cache.

However, if you do other stuff like video encoding or some thing along that line, 8 mb could potenially make a huge difference. Any task that writes and reads from the HD very very frequently performs better with a higher cache. fs2004 simply loads textures and that about it; It does not write to the hd very frequently.

The different ATA numbers are all compatible. The higher the number, the better. However, if your mobo does not support such a high number (like 150), the hd will run the highest number supported (say 133), so that means your hd will essentailly be a ATA 133 drive.

Thank you for the info. I also just picked a guy's brain at my local PC shop. He clarified the interface differences and said that the ultra ata 150 would in fact require an interface card for me to use on my board and all the drives in my price range are ata 100 so it looks like I am getting at Circuit City the 120 meg Seagate 7200 rpm, ata 100, 8 meg buffer. After mail-in rebate only 59.99 USD. Better than any of the newegg.com deals I found and no shipping required. Just have to shell out $99.99 and wait to get the rebate money.
By the way, that's some rig you have there. Isn't the Opteron the AMD equivilent of the Intel Xenon, a server?

Thats correct.

The opteron is a server class CPU. BTw, the opteron's outperform an equivalent xeons in all benchmarks.

Well the ATA *** represents data rate ATA133 is 133 MB/s ATA150 is 150 MB/s

So along those lines, in your opinion, would I expect to get better capturing rates from FRAPS using a Maxtor 200GB 7200RPM 16MB? I just hate the avi format they use since it is such a large format.

What do computers and air conditioners have in common?
They both will work perfectly, until you open windows.

Yes, but not by much.
