The original HD in the Ferrari is a Hitachi DK23FA-60 (60 GB 4200 RPM). The FSB is timed at 266Mhz DDR instead of the advertised 333Mhz. I heard that Acer did this to compensate for the heat. I upgraded my RAM to 1GB and my HD to 7200 RPM because I work with apps that has lots of file access and I have many open applications at the same time. Switching back and forth between these apps is quick. Sometimes I would have Photoshop, MS Outlook, Internet Explorer, Adobe Acrobat, MSN Messenger, SQL Server Enterprise Manager, an FTP client, and 2 instances of Visual Studio .NET open at the same time and I don't experience slowdowns or disk trashing. Graphics is a different story though, especially Direct3D games. While Prince of Persia 2 worked great, Unreal Tournament 2004 demo needs taking a little bit off the graphics details to be smooth. It really depends, because some very optimized games (such as Max Payne 2) plays great, and some assembly-line games (such as EA Sports NBA Live 2004) do not. I wouldn't even think of running Halo on it because it runs a little choppy on my PC which has a P4 3.2Ghz 2G RAM and ATI Radeon 9800.
