Yes. all your PS3 Hard drive is, is most probably a laptop Drive, and is most definitely SATA. you will need to buy a HDD Enclosure/Caddy relevant to your drive, either 3.5 SATA OR 2.5 SATA. i would sway towards 2.5 over 3.5 i highly doubt it has a desktop drive in there. anyway once you have one of those you can format the drive and just use it as an external :). although the £30 your gonna spend on an enclosure and the hassle of formatting it id say just go to PC World and buy an external HDD for aboiut £50
No, you can't have 2 at once on a Ps3 but you can backup your saves and media to a memory stick or Fat32 formatted external drive and use a larger drive, for instructions go on youtube: . Or, you could just use an external Hard Disk Drive and save stuff there.
no at least it would not provide the kind of easy access that a true external harddrive would and would not be very cost effective.
you would have to remove the harddrive which is actually very easy You CANNOT just transfer the hard drive. The ps3 will format the new hard drive therefore erasing all data on the drive.
Yes PS3 uses a standard lap top hard drive and you do not even need to use one from PS3
nope
You can purchase an external hard drive from a variety of places, including retail and online stores. Most stores that sell electronics will have an external hard drives in many different sizes. Online stores, such as DiscounTechnology, also carry external hard drives. Prices vary depending on brand, model, and storage space of the external hard drive, though Sony recommends Seagate external Hard Drive due to it's higher compatibility than other external hard drives with the PlayStation 3 system. Be sure that when you buy one, you have one equal to or greater than the total capacity of your current PS3 to ensure that your data is transferred. If you do not have enough storage space, your data will not transfer at all.
you can delete it by transferring it to an extrenal hard drive, I believe.
It is the same as a laptop hard drive
Hard drive.
obviously,yes
Yes. Any 2.5" (laptop) SATA drive can be used with a PS3.
You may upgrade your hard drive on a PS3. 160GB could be less than $100 depending on where you purchase it.
