On the side of the disc 931Go helpful.
I bought it to put it into a PS3 Slim (250GB to replace a disk filled for a while), 2 screws to remove to access the hard disk and then the 4 screws of the basket of the disc. The change is very easy.
After the disc back in place, simply updater console with the update file (for that you have created is the tree on the USB key), and everything is done very easily.
The 1TB Hard Drive in 5400 trs is not too noisy and not too hot either (a what I could see).
Has completed approximately half this time, he does what I bought.
Very good value
