Installing my SSHD atm and the PS4 system file is taking forever, I should have downloaded it yesterday.
Just in case anyone is wondering what the performance is like
What to buy?
Consider boot times before making your decision on what Hard Drive is best.
Boot Times:
Stock HDD – 25 Seconds to Boot
Hybrid Drive – 20 Seconds to Boot
SSD Drive – 19 Seconds to Boot
Game Launch Times
Stock HDD – 42 Seconds
Hybrid Drive – 37 Seconds
SSD Drive – 36 Seconds
Downloaded Game Launch Times
Stock HDD – 60 Seconds
Hybrid Drive – 45 Seconds
SSD Drive – 42 Seconds
The Hybrid Drive in the above tests was the same one as I bought, just larger but they should perform the same.
As you can see from the above Hybrid drives offer nearly SSD performance for nowhere near the cost for the size of them.
Main reason for buying is loading times on multiplayer games, I can get the edge if I load in faster in BF4 I can quickly jump into a tank and get going before they are all taken and have to resort to running or jumping out a helicopter, etc.

apparently there is a compatible 7200RPM drive but I don't know why you would pick that over a hybrid unless you don't play multiplayer and play a lot of single player games like tomb raider. would have liked if they had tested a 7200rpm drive alongside all of the above.
