And you end up voiding the warranty on the drive in the process by removing it from the external case.I would imagine Amazon would be your best bet.
Keep in mind that if you can find a portable HDD that in most you can remove the casing and pop it in your PS4.
That's what I did with my PS3. Also be sure you get the correct size (2 . 5 inch) for the PS3 because some HDD's may not fit.
Good luck brother.
That's true, if you buy the portable HDD new. If it's used depending on how old it is the warranty will not matter.And you end up voiding the warranty on the drive in the process by removing it from the external case.
