No Speed Benefit in ATA/133 over ATA/100?
Posted on 2003-03-24
PC World has reported in its current issue (April 2003, p. 98, bottom) that there’s no real speed gain to be realized from using an ATA/133 controller and hard drive over an ATA/100 interface. I’ve actually been postponing my upgrading-to-a-new-Dell decision waiting for Dell to advance its motherboards (and hard drives) to ATA/133.
In fact, I recently bought an additional hard drive (Maxtor 120GB, 8Mb buffer) for my current PC (Gateway 450) that’s an ATA/133, and I got this new drive at CostCo! I figured it was a no-brainer that a 1/3 increase in data transfer (100MHz to 133) would translate into a real increase in overall speed in the future. I was assuming that moving this new Maxtor ATA/133 drive to my new-someday-Dell-at-ATA/133 would pay off in speed benefits.
Is PC World correct? Are they right that there’s no real value in waiting for Dell to upgrade its motherboards to ATA/133? Thus, ATA/133 offers no improvement over ATA/100?
Then, can I conclude that my new Maxtor 120GB, ATA/133 would really be no slower in a new Dell ATA/100 than it would be if Dell’s new PC’s had an on-board controller at ATA/133?
