P2 is one of the easiest HD formats to edit. DVCPRO HD, AVCIntra...well suited for editing...unlike AVCHD and H.264 that take a lot more computer processing power.
And never use the internal drive to store the media. That's where you store your OS, apps, music, picture, compressed video files. For editing you always need a secondary hard drive, in this case, and external hard drive. Put your media on the external drive...and make sure to get a 7200RPM or better one.
