Just wondering what you're opinions might be on a new HD for my dual 2.7 powermac. I keep reading a lot of people go with the seagate drives because of the warranty, while others feel better with the hitachi drives. I'm looking at the 300gb-500gb range. Also, anything I should know before doing the upgrade. Seems like a simple deal. My RAM is still stock with 512mb, which I'll hopefully be throwing down for at least 1gb more, maybe two as soon as I get back from NY in two weeks. thanks for any advice, I appreciate it!
