Customer Ratings & Reviews

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!

The WD_BLACK SN7100 4TB NVMe SSD is the kind of upgrade that makes your entire system feel new. It’s fast, reliable, and built for who demand performance without compromise. Whether you’re gaming, editing, or just want the best storage this drive delivers. Even during extended gaming and rendering sessions, temps stayed cool without needing a third-party heatsink. Workloads and doesn’t throttle under pressure.

This is hands down the most power efficient SSD you can buy, with performance as good as any PCIe 4.0 NVMe drive. Compared to the three year old SN850X the power draw is ~60% at full load and ~1% at idle, making it perfect for laptops both from a thermals and battery life perspective. Despite being without a DRAM, read speeds are only an imperceptible 0.7% slower whereas write speeds are a noticeable 9.5% faster. All results are based on Crystal Disk Mark tests on both SSDs which I own.

Quick read write speeds. Stays cool under use. Great amount of storage.

It installed easily and works as it should. I enjoy the 4tb capacity.

Easy to install and format it. Plenty of storage and works great

Solid ssd fast speed and temperatures have been on without a heat sink .

Fast and relaible, does not appear to suffer from some of the NVME/SSD failures on windows 11.

One of the best SSDs to use with gaming handhelds due to its power efficiency. Sucks it might no longer be in stock soon and I hope future iterations can have the same power to performance metrics this particular model outouts.

Not a single issue and it synced up with my ps5 with no issue

Works great and managed to clone everything onto the new drive no porblems

Perfect for my PC. Needed more space and this was simple and works great. Bought before the price spikes hit and super grateful

Upgraded the storage for my lenovo legion laptop from best buy and this helped my storage needs to install all my photos videos and video games onto the 2nd drive.

NOT SO GREAT. purchased for legion go S. worked great but than upgraded device and threw into my PC. nothing but issues basically a paper weight

No issues with the WD SSD drive. Works as expected!

Very good hard drive for my rog ally x doesn't heat up to much either !
