A German magazine got their hands on a PS4 and in true German style did some tests.
After 10 minutes of operation
- PS3: 0.83 sone
- PS4: 0.815 sone
According to the magazine, a "slight noise" is audible from 40cm (= 15.75 inches) distance.
After 60 minutes of operation
- PS3: 2.1 sone
- PS4: 0.83 sone
"ComputerBild revealed the specfication of Playstation 4 HDD and it reads something like this: "HGST 2.5", 5400 RPM".
In addition to this, ComputerBil also revealed that Playstation 4 HDD supports 2.5" drives up to 12.5mm height.
PS4 HDD speed is capable of speeds in the range of 80 to 100 MB per second"
I think the noise results provide more evidence that the overheating issue isn't factually correct.
The HDD is a bit disappointing as i was hoping for a 7200 RPM HDD but that might have been an unrealistic expectation. Is the 80-100MBps any good?
