Use any hard disk (3.5", IDE) you could wish in your PS3.
The Xecuter PS3 HDXT is a caddy type frame that plugs into the PS3 internally where the 2.5" Sata drive would normally slot. You then clip on the matching faceplate and bingo you now have a clean external Sata connection. No frills and no fuss. You can now add any hard drive you wish and connect it any way you wish. We have also designed a simple but cost effective Sata to IDE convertor.
