8mb buffer or 2mb?

[Dswissmiss]

hi guys.

i'm looking to get my friend another hard drive. he has a dell dimension 4400 with 40 gigs. i'm wondering if has raid, and how to find out whether it has a 2mb or 8mb buffer, because i'm thinking if i get him a 8mb one, it will run at 2mb if his other hdd is 2mb.

thank you

edit: ok, i just realized IDE interface can have 2 drives, but i'm still unsure of the buffer question

They will each run at rated speeds and the 8mb will process faster.

The buffer is nothing more than a memory chip where the data transfer goes from being a mechanical device (spinning disk) to a purly electronic device or vise versa.

the 8 will perfrome at 8 and the 2 at 2 :) the 8 will not be affected by the 2 and under perform

if that is what you are asking. lol kinda confusing

I would doubt very much if it has raid
