Hi there, I have a Penryn (Core 2 Duo@2.4GHz) Macbook in the black plastic enclosure, with 4GB of RAM, X3100 integrated graphics, and a 250GB hard drive. Obviously, by today's standards it is not a screamer, but I do not want to invest in a new laptop yet. So I am looking into my options for accelerating the machine to any noticeable extent. There is no room for more RAM, unfortunately, as the machine supports no more than 4GB. So the question is rephrased as such: Would a larger/faster hard disk result in better performance? My machine has a little more than 70GB of free disk space at the moment. Please do not suggest an SSD as I cannot afford 250+ GB drive of this type! Perhaps one of those Seagate 'hybrid' drives would do the trick? Or perhaps I should format the hard disk and reinstall everything in hopes of having a more responsive system? Many thanks. UPDATE: Apologies for the typo in the title—unfortunately, there seems to be no way to edit it!
