I just checked it is 5400 rpm. Unfortunately here in Turkey options are limited. We have pretty much all GPU or MOBOs in here but I believe 2.5 inch hdd market is extremely limited. I got an SSHD one though. I read some PS4 performance reviews, it helps with load times a bit. I just really wish a 2TB option was on the table for me though. I could just be done with it.
There isnt a 2TB 9.5mm SSHD released yet. Your only option for 2TB is a regular 5400 HD.
