    It was exactly what i needed to boost speed and liaidng time, ive been using a basic hard drive for the longest time and once i made the switch loading time for files on this is basically a almost instant response.

    Installed in my PS5, and it works great. Easily more space than most people could use with almost no storage management. Just remember to get a compatible heat sink along with it.

    Very easy to install. I did however have to buy an additional hold down bracket to work with my laptop but that's a Dell issue. Great hardrive.

    These are good drives for the price. Get them on sale and you're getting a great deal for Gen 4 speeds. I picked up two 4TB drives on sale @ $300 each. The software suite is actually nice. I used Acronis to clone one of my old drives and had no issues. Using the Gaming Mode, I'm still unsure if it makes a difference in load times. But they're fast on Gen 4 regardless.
