Does IDE Buffer Size no longer matter?

I'm looking to purchase a new IDE drive for an older machine and I noticed that the "NEW" 7200.10 Seagate IDE hard drives at 80 or 160GB have a small 2MB buffer. This is in contrast to my 6 year old WD80JB IDE drive which has an 8MB buffer.

Anyone know why these "new" Seagate drives have a smaller buffer size than the older AND new WD Caviar Blue IDE drives? Is Seagate somehow more efficient with their buffer memory when using perpendicular recording technology?

I really like the performance of my WD IDE drive and don't want a crippled slow Seagate drive if I can avoid it.

Thanks.
 
Those drives are 2 generation old and extremely small. I do not think they still make them that small.
The buffer is so small because at the time they were made they were extreme budget. Yours is big because at the time it was made it was high end.
The high end seagate drives have 32mb buffer
 
I'm only interested in IDE drives and I don't think even the largest IDE drive (500GB) had a greater than 16MB cache. I bought several 250GB Seagate 7200.10 IDE drives with 16MB cache but these are no longer available. It makes me think these 2MB cache drives are for notebooks? They are small enough to fit.
