    • Great drive at a great price with a great, known brand.
Capacity: 2TB Style: M.2 2230 for Handheld Gaming
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. ... show more

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. ... show more

    • Good drive....expensive now!
Capacity: 1TB Style: M.2 2230 for Handheld Gaming
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.

    • Extremely fast and very reliable, impressive thermals, best 2230 ssd
Capacity: 2TB Style: M.2 2230 for Handheld Gaming
I was skeptical of the performance of this SSD, since I typically only buy the best, and have now multiple SN850x, so this sn770 felt like a downgrade. But it turned out to be the fast 2230 drive I have ever tested, and it has really good thermals. I'm running most of my games directly off it. It's very reliable , has unmatched value for money, and it comes with bunch of tools for speed testing. Installation was peice of cake, especially after using the automated SSD cloner. Overall, if you are able to use 2280 instead, then use those. If you must use 2230, then this SN770 is by far the best. It's massive upgrade over my previous sabrent ssd. If your device (like my GPD Win Max 2 2023) has only two slots, one is 2280, and other 2230, and you want the best, then for sure this sn770 2TB for the small 2230 slot, and pair it with 2TB SN850x or 990 PRO in bigger 2280 slot. ... show more
