I've just recently changed motherboard to the GA-7VAXP with Promise ultra ATA133 raid controller on it and fancy trying out a mirrored raid setup. At the moment I have a 20Gb Maxtor drive thats been fine for a few years and a Quantum Fireball 10Gb. I'm putting the smaller disk into a second system and selling it. With the profits I'm looking at buying a couple of ATA133 driver, probably between 30 and 60gb. Anyone have any recommendations of which disks to use. Access times, cache sizes etc? Looking to spend about £50-70 per drive if possible... The only online ones I have found which are ATA133 are Maxtor but the system admin at my work says that he has read about compatibility problems with Maxtor drives and Promise Raid controllers. Any suggestions would be most welcome.
