You can cut down load times on a MacBook by adding a solid-state disk drive to the system; however, the drive won't do you any good unless it is formatted correctly for Mac OS. The only difference between a Mac hard drive and a PC hard drive is what file system it's formatted in; Mac hard drives usually come formatted in FAT32, which will work on both Macs and PCs, but isn't optimal for the MacBook's operating system. PC formatted hard drives use the NTFS file system and need to be reformatted to work with Mac computers.
