Hard drive.
You jailbreak the firmware.
The harddrive is the size of a standard notebook harddrive not a PC size harddrive. So you can not fit it in the smaller spot required for the notebook size harddrive
the hard drive crashes
It is a 320 GB model produced from September 2010 until August 2011 when it was replaced by the 320 GB model CECH-3001B

Get a PS3 you noob
Yes PS3 uses a standard lap top hard drive and you do not even need to use one from PS3
PS3s were made with different size harddrives

All PS3s can have the Hard drive replaced with a 250 GB or larger size hard drive, but the 250 slim is the only 250 GB PS3 Model Sony has sold.
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.
You can use a hard drive from a laptop, but a normal size computer hard drive will not fit. I"m not sure how to install or format the drive, but do an internet search on "PS3 forums" and you will find the official PS3 forums. Go digging there and you will find how to get this done.
You may upgrade your hard drive on a PS3. 160GB could be less than $100 depending on where you purchase it.
The only difference besides price is the hard drive size.
