However, they also generate both noise and heat. Solid state drives, also known as SSDs, are many times faster than hard disk drives and have no moving parts to wear out, but typically offer less capacity for the same price.)
- Maximum Read Speed: 7300 megabytes per second (The greatest speed at which the device can read information; for example, opening files.)

A: I'm by no means an expert, but BB has a habit of using unique SKUs for their products. They do this because their price match policy is based around model numbers and SKUs matching. Because this has a unique BB SKU, any price match requests against the same product at Amazon would be denied. That said, its also possible BB requested a unique model from WD with different tunings. So do what you will with this information.

Q: will this or the 4tb work for ps5
A: The 2Tb and under works with the PS5, I have this SSD drive in 2Tb form installed in my PS5 and it works flawlessly. Avoid installing drives bigger than 2Tb because the PS5 controller has trouble controlling larger drives, this is a known issue well documented on the PS forums.

Blazing fast NVMs
I had purchased this drive on December 21st,2025 for $250 out the door. It was on special marked down from $349.99 and even though the specs on my revent gaming PC build were great, I wanted another 2TB drive for storage...its crazy now only a few weeks later this same drive is now listed for $549.99 and I feel prices will just keep going up. I ended up making this drive my main, and the other I had my storage backup for games. Game sizes nowadays are HUGE and a 1TB won't get you more than 5 games of high-end titles nowadays. This SSd does run a tad hot, which the speeds they hit is expected. There's a version of the SN850X mounted inside a thermal spreader from WD, but for 25$ on Amazon, you can get a pretty good one. And the fact that it decreased 20 °C on high load with one, was worth it. This drive is great, but at the current cost of what it's listed, I hesitate to say it is. If.you see it on a great price,snag it,because they will indeed continue to rise Specials happen quite often in the PC world. But this regardless is one of the best NVMe ive used and was agreay buy for exactly what I needed!

Works well and feels fast
I haven’t done any detailed speed testing, but in normal use everything feels fast and responsive. Coming from an older laptop, the difference is very noticeable, especially with loading, installing and opening programs. The 2TB size is also really nice to have because I wanted enough space for creative work and larger files without immediately worrying about storage. So far no complaints. It does exactly what I needed to do and I think with an SSD, that’s kind of the best sign.

Blazing Fast and Super Reliable
This SSD is lightning quick — Windows boots in seconds and large file transfers are done almost instantly. Perfect for both work and gaming. Load times in games are nearly nonexistent. Easy install and runs cool even without a heatsink. Excellent upgrade for any high-performance build.
