I swapped my 40GB PS3 hard drive with 120GB Western Digital. The process was real simple and took less the twenty minutes. If you use an external drive make sure you backup your data first as game saves and downloads don't carry over. Purchased content can be re-downloaded at no extra cost to you via the Playstation store. You can use a thumb drive to backup game saves.
All in all a very easy process. Recommeded if want bigger internal space or if you don't have room to keep an external drive plugged in to the PS3.
