It doesn't matter if you have the 20GB, 40GB, 60GB, or even the 80GB PlayStation 3--you can always use more storage space. All that available harddisk space quickly disappears once you start downloading games, demos, and HD videos. Fortunately, Sony has designed the PS3 to allow console owners to perform their own hard drive upgrades. You can go out and select your own hard drive instead of being forced to buy an official first-party harddisk accessory. However, giving console owners that freedom means aspiring upgraders will need to know how to select the right hard drive upgrade and the proper installation technique.

Harddisk manufacturer Seagate supplied us with a 160GB Momentus 5400.3 for our upgrade.
The first step to replacing the harddisk is going to the store or visiting an online retailer to pick up a new harddisk. The PS3 is compatible with just about any 2.5-inch SATA notebook harddisk. The physical size of the harddisk is important because it has to fit the PS3's 2.5-inch drive tray. As far as storage capacity goes, it doesn't make sense to go through the trouble of upgrading unless you go big: We're talking 160GB, 250GB, 320GB or even 500GB.
Once you have your upgrade drive, the next step is to backup the data on your current PS3 hard drive to an external storage unit. You can skip this step if you aren't attached to your music, videos, and game saves, but most of us will probably want to save all that information. The PS3 has a built-in software backup utility that can copy the PS3's hard drive contents to an external storage device, such as a USB thumb drive or a Memory Stick. The removable storage device must use the FAT32 file system in order for the PS3 to recognize it. If you have an external hard drive that's formatted in NTFS, you can use the Disk Management utility in Windows to reformat the drive, but you'll need to create partitions on large external hard drives because Windows can do only FAT32 on drives 32GB or smaller.
