Hi there. My friend and I both got shiny new MacBooks and upgraded the internal (stock) 5400rpm drives to the 7200rpm Hitachi drives. They sure do seem faster but Xbench says otherwise. With my stock 5400rpm drive I consistantly got a Disk Test result of 34.00. With our new drives our best results are <30, between 27 and 29! I have the Seagate on order and will be testing it tomorrow, but if anyone has a MB or MBP with a 7200rpm drive (any kind) could you please post your Xbench Disk Test results along with make/model? It'd be appreciated. Right now I'm wondering if the Hitachi has NCQ enabled by default, which I don't believe the MB/P support. Anyone know? [Edit] See post #5 for some more info on NCQ and SSC support/impact on Mac machines. Thanks!
