Hard disks - jargon
Posted on 1998-09-10
I am about to buy a promise fast track pci raid controller for my video work and 4*10gb drives but it says i need to buy Ultra ATA drives.
I have been looking through magazines and am totally confused. Some manufactures say their drives are ATA others say UDMA33.
I need to buy drives with the fastest access time and fastest rotation speed.
The Quantum fireball has 9.5m/s access time and 5400 rotation speed and is ATA.
But the Maxtor's have 9m/s access time and 7200 rotation speed but are UDMA33.
Is Ultra ATA the same as Ultra DMA?
If not what's the difference?
And why can I only use ATA drives?
