    I was able to catch it on sale for 200 dollars off which made it very worth it I’m a photographer so I store all my images else where the regular price of this is pretty pricey but if you’re able to catch this on sale I suggest you get it if you need more storage

    I purchased this SSD driver as the installation path for steam games and to store some data. The reading and writing speed is very fast, and steam games can run on it without any problems.

    This is a fast little device. Just keep in mind that you have to unsave your password to save the annoyance of signing in every time you power up your computer. Otherwise, the device will be locked until you enter the password.

    I loved theses SSD's! This is my 3rd one that I personally own and I back up alot of photos and videos every month. Fast, reliable and also very small to carry with me especially when I travel for my business. I have the best peace of mind knowing that my clients photos and videos are safe

    Works great -- easy and quick to use when I needed to transfer all the data from a failing PC. I captured everything I needed/wanted with no problems. Since then, I've purchased a second drive -- to have on hand for data storage. Easy to carry with me.

    Drive works as expected. Size is perfect. Speed is great. The cord that comes with it is extremely short. Other than that, there are no issues. I will buy this one again!

    So far, the SSD is working OK, I decided it was too large to test with Verification utility so I will trust BestBuy that it is authentic. The supplied cable is just a tad over 6 inches which I feel is too short, would have suited me better if it were at least 12 inches.

    I am very happy with this SSD so far. It is very small and light, works as advertised, and the price was more than fair, enabling me to increase the space of my Time Machine backup to 4TB from my previous 2TB. Long-term experience is yet to be had.

    I needed at least 3TB in a hurry for a video project. This was perfect for my needs. I tested the write speed and it was over 4X as fast as my 2 TB external SanDisk drive.
