i just noticed my main video hard drive doesn't seem to have a buffer at all.
how much would it help to have an 8MB buffer on a hard drive when capturing vhs through my canopus advc-100?
will this help with dropped frames?

All hard disks made within the last 15 or so years have a buffer.
When doing video work, the hard disk speed is very important. I'd say a couple of Maxtor 300gb 16mb buffer drives in RAID 0 would be fast enough for most video.
Usually, a larger buffer means faster random small file reads/writes while a faster RPM means faster sustained reads/writes.
Now only if the Raptors had a 16mb cache...

so basically with large files, such as capturing video, it will make no difference?
i realize a faster RPM is important and my system won't work with the drive you suggested.
what i'm looking at his a western digital 8MB buffer 7200RPM 160GB.
is there a brand that is just made for video caputure?
it would have to be IDE and i'm using a gigabit G4 so size is limited to 128GB.
i currently have a seagate 60GB 7200rpm, and i would be replacing the original IBM 20GB drive.

The 8meg buffer does help, but you really shouldn't have any problems with any 7200 rpm drive (even those with a 2mb buffer) if you're only working with DV. You can capture and edit video quite capably on a 4200 rpm drive so any 7200 rpm drive is just going to work better than that.
That being said, I have the 80 gig Western Digital drive with the 8meg buffer and it works fantastically for video.
