Which is faster....Ultra scsi or Ultra ata100


Recommended Posts

I am rebuilding my computer and I am curious which would be faster for my comuter. Having my OS and swap file on my Ultra scsi drive (not ultra160 but just ultra scsi) or having it on my IBM 40gig. Both drives are 7200rpm, the IBM is a 60GXP which has 2MB cache and works at uata100 while the scsi drive is a western digital 4.3gig with 512KB cache but has slightly faster access times...7.9ms vs 8.5ms of the IBM. I know scsi is much less CPU dependant but also this is 2 generations old as far as scsi is concerned. I just am not sure which would run faster. Anyone have any ideas?

SCSI for sure, 3 reasons really

1. You already said, it's less CPU dependant.

2. Faster access, nearly 10% faster.

3. Seperate Drive which is always good.
