With this Best Buy offer, you can now massively expand your system’s storage, with the WD Black 8 TB SSD at $260 off.
The WD Black SN850X 8TB SSD is designed to meet the needs of gamers and creators who require both speed and space in a single drive. It is powered by PCIe Gen 4 performance, an integrated heatsink, and PS5 compatibility to provide the type of storage that can meet the requirements of the most demanding workloads and simultaneously future-proof your system.
Large-capacity SSDs have become more useful since new games and applications are taking up more space. Having 8 TB on the same drive means no fears of removing older titles or using two or more storage devices. In the case of desktops and consoles, such as the PS5, this type of upgrade will provide a smooth performance and ample room in years to come.
Best Buy has reduced the price of WD Black SN850X 8TB by $260, making it available at $639.99 instead of $899.99.
Note: The listed deal is accurate as of September 29, 2025.
Technical Specifications
First of all, let us take a look at the specs of the WD Black 8 TB SSD:

|---|---|
| Capacity | 8 TB |

Is It Worth Buying WD Black SN850X 8TB SSD?
Yes, the WD Black SN850X 8TB SSD is a purchase to make when you are not willing to compromise on the storage capacity and speed.
The drive supports PCIe Gen 4 speeds of 7,300 MB/s reading and 6,600 MB/s writing. Those specs are good enough to support not only gaming but also content creation workloads, such as 4K video editing and large project files. The inbuilt heatsink guarantees a steady operation, particularly within a PS5 or compact desktop, where heat has the potential to affect performance. The 8 TB capacity is what is unique about this model.
Large titles can very rapidly fill most gaming PCs and consoles. In fact, these days a single game can easily be over 100 GB. You can save dozens of AAA games, media libraries, and creative works without worrying about space with this drive. It is especially useful when the user wants to have one big drive rather than many smaller ones. It remains expensive in comparison to lower-capacity SSDs.
Also, depending on the needs of the user, a 2 TB or 4 TB could be cheaper. However, to those who desire uncompromising space and speed in a single solution, the SN850X 8TB is one of the best options one can have.
Pro Tip
You should also update your console to the most recent firmware before installing this drive in a PS5. This guarantees optimum compatibility and performance of Gen 4 NVMe drives.
WD Black SN850X 8TB SSD Deal Overview
The WD Black SN850X 8TB SSD is now priced at $639.99 with this discount, which is significantly lower than what it used to be. Discounts like these are uncommon on high-capacity SSDs, particularly the higher-end ones with heatsinks that are compatible in both desktops and consoles.
The SN850X 8TB is a powerful long-term investment with its combination of speed, huge capacity, and PS5-ready design. This Best Buy offer is an opportunity to upgrade to premium storage, whether it is a high-end gaming rig, a console upgrade, or a professional storage capacity increase.
