This is a fast little SSD. It also stays very cool and no matter how hard the laptop runs it, it has remained at 100% health the entire time. Very durable and high quality SSD. Have no complaints!!!!!

Western Digital makes quality hard drives, period. The performance is always good, they always seem to work and the cost is better than buying from the computer manufacturer. I purchased this for my college freshman's new laptop. You couldn't get anything more than a 512G hard drive and that wasn't going to be enough. Installing was easy after we figured out how to open the laptop housing. The WD drive fit as expected and worked perfectly after we made a direct backup of the original drive. Compatibility was never an issue and 2tb of capacity was exactly what we needed.

Massive upgrade for my Steam Deck! I installed the WD_BLACK SN770M 2TB in my Steam Deck, and it’s been amazing. The install was super easy, and the speed difference is instantly noticeable — games load fast and everything feels smoother. Having 2TB of space means I can keep my whole library on deck without worrying about running out of room. It runs cool, performs great, and so far has been rock solid. If you’re thinking about upgrading your Steam Deck’s storage, this drive is 100% worth it.
