Got this on a sale for $499. Can't find anything else that comes close in price and quality. Installed it on the Legion 5 gen 10. Didn't have to change anything in the BIOS. Laptop read it instantly on first boot. Tested speeds on AIDA64 and HWINFO. Speeds were as advertised. Now i have 3TB of steam games and 4k movies that can be loaded in an instant

Placed this into a Ugreen Thunderbolt 4 enclosure and this thing works great for all my video files and code compiles.

Drive failed after 3 months. Sent drive in for RMA and originally was offered an upgrade until support claimed it was "damaged" after holding it for a month. Will edit this if I end up getting a replacement or refund.

I installed the WD Black SN7100 4TB in my Lenovo Legion Go 2, and I’ve been really impressed so far. Performance is fast and smooth, but what I like most is that it runs cool and doesn’t seem to use much power, which is a big deal for a handheld. I was a little worried about heat and battery impact with a Gen 4 SSD, but it hasn’t been an issue at all. Load times are quicker, everything feels more responsive, and I haven’t noticed any thermal throttling. One thing worth mentioning is that this drive is extra thin. If you’re upgrading a Legion Go 2, you’ll want to use a thermal pad around 1.5mm thick, because the SSD itself isn’t thick enough to make good contact with the original thermal pad. Once that’s taken care of, installation is straightforward and it works great. Overall, it feels like a really good match for the Legion Go 2 if you want a lot of storage without adding extra heat or power draw.

At first I loaded as a clone drive MBT, you will only get 2TB. Format as GPT and you will get all 4TB of storage, actually 3.7TB. i use this as my gaming storage and work files with a 1TB SSD as a boot disk. Works amazing for the price. I have not done any speed testing but I blink and my game is loaded, that's all I have to say. So good!
