A:AnswerIt doesn't list gaming systems as being compatible but it works perfectly fine for my Xbox one so as long as your PS4 is USB 3.0 you shouldn't have any issues
A:AnswerIt is a more recent model and it is fast and quite.
The 8T models are noisy and have problems.
My 6T is the best unit I have owned to date from the company.
I have two 5 Ts and two 2Ts.
A:AnswerIt is compatible with MacOS and Windows. When you connect the drive to a Mac, there is a folder with software for the Mac, but I just use it with Time Machine without installing anything.
A:AnswerYes, you can designate the location of the time machine files. I partitioned the drive into two 3 Gb volumes, one for time machine and the other for general use.
A:AnswerUSB 3.0 is backwards compatible with a regular USB 2.0 port on older computers. You will see reduced transfer speeds since it's not a USB 3.0 port but you will not need additional cables or dongles to connect to an older PC with USB 2.0 port(s)
A:AnswerHello JJen54,
Since this drive doesn't come with a software for password protection, you'll need to use a third party software.
