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.

Bought “Used Like New” and definitely work as new, fast and quiet operation, any issue with connectivity or formatting

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.

Nice drive that works great in my Surface Pro 11. Was $109 when I bought it in December 2025. March 2026 it's $249. It's good but I'd never buy at the current price.

Plugged this thing into my Steam Deck and it works great! Super easy to install and the space is worth it for the price.

Good

Top Speed allerdings für die Ally als externe Festplatte bissi zu schnell ^.^

I upgraded my Steam Deck with the WD_BLACK SN770M 2TB and wow—what a difference! If you’re tired of juggling game installs or waiting on slow load screens, this drive is 100% worth it. Installation was super easy—it’s the exact 2230 size the Steam Deck needs, so no adapters or awkward fitting required. Just popped it in, reinstalled SteamOS, and I was good to go. The Steam Deck recognized it right away. The 2TB storage is a game-changer. I’ve loaded up my entire library and still have room left. No more deleting games to make space! Plus, it’s crazy fast. Load times are significantly shorter and navigating through menus feels way snappier. Also worth noting—this SSD runs cool and quiet, even during longer gaming sessions. That’s huge for a handheld device. ✅ Pros: Perfect size for Steam Deck (2230 form factor) Super fast (up to 5,150MB/s) Massive 2TB storage—say goodbye to space issues Reliable performance and runs cool Easy to install, even if you're not super techy ❌ Cons: Doesn’t come with a heatsink (though not really needed for Steam Deck) On the pricey side—but you get what you pay for If you're serious about getting the most out of your Steam Deck, this SSD upgrade is a no-brainer. I’d do it again in a heartbeat!

يعمل مع اجهرة الكمبيوتر والستيم ولكن لايعمل مع اجهزة Xbox لانها تدعم فقط ch sn530

Tudo certo, chegou na embalagem original lacrada e funcionou perfeitamente. Só não dou cinco estrelas porque chegou em um envelope de papel madeira e a caixa do SSD estava amassada. Considerando que é uma peça cara e sensível, poderiam ter mais cuidado com o transporte.

It’s Not worked out as per details given so returned back
