Your PlayStation 3 does not come with an unlimited amount of storage. Its hard drive won’t last forever either. Changing its hard drive or adding more storage for it should not have to be a challenge. These 2 hard drives are proven to work with PS3 systems:
DIGISTOR 500GB External Hard Drive for Playstation 3: it is a USB 3.0 media drive for PS3 gaming console. It adds 500GB data capacity to your system.
320GB 2.5 Inchs SATA Playstation PS 3 Hard Disk Drive: you are going to need one of these if your PS3’s internal hard drive is fried. You could use other comparable models inside your machine as well.
If you are running out of space on your PS3 or need more storage on it, the above hard drives have you covered.
