    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.

    I bought it at a discount when I caught up with the event. It is very cost-effective. It is used to upgrade my razer blade 14. The SSD speed is very fast, the capacity is large, and it is a good shopping experience.
