Excellent 4TB drive. Easy to install and works like a champ. Highly recommended. I will be purchasing a second one very soon.

- Working exceptionally better than expected - Amazing customer service - Relatively easy to set up - Worth the money

Ludicrously fast, Decent value, Over-performing

Lots of storage for not much money. 4.0 speeds available (I am only using it a 3.0 slot)

So easy to use

Plug 'n' play with 3rd party external enclosure I can't believe how far we've come in just the last 2-3 years in regards to availability, speeds, and reliability, plus even accessibility which makes it just the best recommendable upgrade anyone can do, whether it be for an older laptop needing a boost to speeds, or even as an addition to a gaming system as a 2ndary drive. I'm, however, using this as a nice everyday-carry item where I put all my larger files which transfer extremely fast, and batches of smaller files which transfer completely before you even have a chance to look down twice at your keyboard. Thanks Newegg for carrying this, and thanks Crucial for continuing to make products that are a true bargain while attaining superior performance.

Reasonably priced for the performance and storage level. Typical Gen4 performance (fast) on reads, cacheless has its good and bad side.

- 2 TB for the price is phenomenal - Speeds are pretty good, obviously limited by SATA III

As title says. Great product. Runs very well and at high speed. Now, make sure you have a Type-C port and also make sure your Motherboard supports USB 3.2 Gen 2x2 in order to gain from the 2000 MB/S. If it only supports USB 3.2 Gen 2 or below then it will run at a max speed of 1000 MB/S which is pretty fast, still. It also doesn't specify if it comes with a cable. Yes, a Type-C cable. Not a USB cable. So like I said you need a Type-C port.

Cheap and it works


Being Gen 5 it makes a big differnece compared to Gen 3 and even Gen 4

Pretty Fast, high endurance, stays cool great price when on sale. Runs at advertised speed

Have two of SP UD 90 m.2s, got 1T from another online store months ago and its surprised how well it was running. So, got another one , 2T from newegg recently as storage. Both run around 4900/4500, per CrystalDiskMark, and able to transfer large 50-70 Gig folders without much up/ downs.

Wow, large file transfers / access are a breeze. Best NVMe ever (as of 6/2025)

For the price it works and provides the speeds as advertised which is like around 3.7 GB/s. Well see if I have any longevity issues like some of the lower reviews on here but installed today and speeds and temps are great thus far.

Cheap and very fast. First time user of SSD will be amazed at boot times.

The WD BLACK SN850X 4TB w Heatsink drive is excellent as a fast (6960 MB/s R, 6560 MB/s Wr, in my system) PC boot drive as well as for an additional DDR4 storage drive. My PC boot time is now ~15 seconds faster than the original slug SSD. Snappy general use too.

Was part of a bundle deal cant complain works good
