A:AnswerUniversal Serial Bus. The WD easystore is USB 3.0. It's much faster than 2.0. The USB cable connects to your PC or video game console, the other end of it is connected to the external HDD with SATA port.
A:AnswerYes you can, I actually got this as a gift to my brother for his Xbox One. I use a similar line of the same brand for my PS4 pro. So yes, you can use it for the PS4 :)
A:AnswerAbsolutely. I've been using it on my PS4 since September, and it's been working great. It does have to be formatted specifically to the console when you first use it, which won't allow you to use it on a computer afterwards. That said, if you're only concerned about using it on the PS4, then you have nothing to worry about.
A:AnswerThe drive comes with the necessary USB cord and nothing else. I purchased a leather zip pouch carrying case for one of my drives (purchased a total of 9). We have them on every computer in the office and I use the extra for my laptop. Ransomware attacks will make you do serious backup routines. We do a backup of each of our computer hard drives every night when we leave and store them in a safe place. The 1TB storage is probably plenty for your computer unless you have a ton of photos or videos. If that's the case you might also want to look at cloud storage just for those.
A:AnswerIt should work perfectly fine with any laptop or desktop with a USB 2.0 or 3.0 access. If it's plugged into a 2.0 USB, it will simply run at 2.0 speeds vs 3.0 speeds. Keep in mind that you may need to format it to exFat if you plan on writing to the drive from a Mac. Either that, or you will need software like Paragon NTFS that allows for a Mac to write to NTFS formatted drives.
