Ok, I need a new hard drive for a 1.2Ghz G4 iBook. My options are: Order online at get a Western Digital Scorpio 100GB 5400rpm 2MB Cache drive for £72.45 and get it tomorrow. Or... Go and pick up a Samsung HM100JC 100GB 5400rpm 8MB Cache drive for £84.49 including bus fair. I could wait until tomorrow and get the cheaper one but I would quite like to put this 'book back together again today so as not to have loads of parts lying around my floor. I'm trying to keep the costs down with this 'book so the cheaper one is appealing but then the other one also has four times as much cache. Which one would you get?
