If your hard disk is running out of space or has generally become slower, the best option is to upgrade to an SSD. SSDs are faster than HDDs and guarantee efficiency during high-end gaming, video editing, and 3D rendering. Which is the best SSD to upgrade to between SN850 vs SN850X?
Well, to help answer that question, this guide seeks to give a comprehensive comparison of both SSDs whose manufacturer is Western Digital (WD) company. To help you better understand both SSDs, this article will compare them based on storage capacity, speed, purchase price, specifications, game performance, and overall performance.
Both WD Black SN850 and WD Black SN850X are solid-state drives (SSDs) manufactured by Western Digital. With regards to the release dates, SN850 came first. Essentially, the SN850X is a successor and potential replacement of the SN850.
Sometimes, when you want to buy a new NVMe SSD, you may wonder which one to choose from among the two. In this section, we'll briefly introduce the two drives and then extensively compare them based on different aspects.
1️⃣ WD Black SN850 SSD
The SN850 was officially released in February 2021. As the first of its kind regarding PCIe Gen4 technology, this SSD is suitable for top-tier gaming. It comes with a storage capacity of up to 2 TB, allowing you to store larger game files.
The sequential read speed for this drive is 7,000MB/s, while its sequential write performance is 5,300MB/s. To help you customize your gaming needs, the SN850 has downloadable WD_Black Dashboard software.
2️⃣ WD Black SN850X SSD
The SN850X was officially released to the market in August 2022. This SSD from Western Digital was meant to improve on the SN850. It has a minimum storage capacity of 1 TB and a maximum of 4 TB. It has a WD_Black Dashboard software that controls your RGB style and checks your drive's health.
It has a top-notch sequential read speed of 7,300MB/s and a write speed of 6,300MB/s. This NVMe drive brags of unique features such as overhead balancing, predictive loading, and adaptive thermal management.
With a brief introduction to the two SSDs, it's time to compare and understand them deeper. Although both drives are from the same company, they have varying features. We'll compare them based on specifications, price, capacity, game performance, and overall performance.
Probably, the first thing that comes to mind when you want to choose between the two SSDs is their specifications. This could cover speed, storage capacity, warranty, interface, form factor, etc. Below is a table that compares SN850 vs SN850X based on specifications.

- The 4 TB model is available for $289.99 on Amazon and $349.99 on WD's official website.
You can now select and purchase your best storage capacity based on the above prices.
The SN850X offers a storage capacity of up to 4 TB. It provides storage options of 1 TB, 2 TB and 4 TB. On the other hand, the SN850 provides a maximum storage capacity of 2 TB with storage options of 500GB, 1 TB, and 2 TB. The difference is that the SN850 lacks 4 TB while the SN850X lacks the 500GB drive option.
Moreover, the RBG cooler option is available for the 1 TB and 2 TB versions of the SN850X, while the SN850 uses non-RGB cooler options for all its drive capacities.
SN850 enhances the drive's responsiveness in Game Mode by suppressing low-power states. Unique approaches such as overhead balancing, predictive loading, and adaptive thermal management were applied in SN850's Game Mode 2.0.
It also uses a speculative loading algorithm to get information about an upcoming queue depth when processing most games' workloads. SN850X uses the WD_Black Dashboard software to optimize gaming activities on your drive. It checks the drive's health status and provides the relevant tools and settings to enhance your gaming experience.
In addition to turning Game Mode on/off via the dashboard software, SN850X comes with Game Mode 2.0, which allows you to automatically detect when a game gets launched.
Powered by its PCIe Gen4 technology, SN850X has sequential read speeds of 7,300MB/s and sequential write speeds of 6,300MB/s. With these high speeds, the SSD guarantees reduced loading time when playing games and faster data transfers. This drive is specifically important in applications that need to access large files quickly when running.
This includes applications related to gaming, 3D rendering, and video editing. The SN850 also uses the PCIe Gen4 technology to enhance responsiveness and your overall gaming experience. This is made possible with sequential read speeds of 7,000MB/s and sequential write speeds of 5,300MB/s. The SN850 speeds are also high, just like in SN850X, although the latter is slightly faster.

Since they are products from the same company, SN850 and SN850X have many features in common. Despite that, the factors you can consider when choosing between the two include speed, storage capacity, and purchase price. The SN850X has sequential read and write speeds of 7,300MB/s and 6,300MB/s respectively.
Both speeds are higher than that of SN850, which has 7,000MB/s and 5,300MB/s, respectively. Based on this factor, you can choose the SN850X if the application you intend to run requires high performance to boost its efficiency. However, if you intend to run average applications that don't necessarily require high speeds, you can be comfortable with SN850.
Regarding storage capacity, SN850X offers up to 4 TB of storage, while SN850 only offers 2 TB. Again, if you intend to run programs that require large storage, SB850X is the best option. However, if you can comfortably work with a storage capacity of 2 TB without any interference, you can pick SN850.
Lastly, SN850X seems to cost less than SN850. For example, 1 TB and 2 TB of SN850X cost $79.98 and $129.99 respectively on Amazon. On the other hand, 1 TB and 2 TB of SN850 cost $85.00 and $149.99 respectively on Amazon. This is something unique with the SN850X since it comes at a lower price, yet it provides better features.
Since most people consider price when purchasing items, I think SN850X gets better placed between the two SSDs.
Deciding to upgrade your computer to SSD is always a good decision since you will boost your system's speed and performance. However, upgrading to a new drive is not easy, especially if you have a lot of data to move with. Sometimes, data may also get corrupted during the transfer process.

- All data on the destination disk will be completely erased, so take care.
Step 1. To start copying/cloning an entire disk to another, choose this disk as the source disk under "Disk Mode" and click "Next".
Step 2. Choose the other disk as the destination disk.
Step 3. Check the disk layout of the two disks. You can manage the disk layout of the destination disk by selecting "Autofit the disk", "Copy as the source" or "Edit disk layout".
- "Autofit the disk" makes some changes by default on the destination disk layout so that it can work at its best status.
- "Copy as the source"does not change anything on destination disk and the layout is the same as source disk.
- "Edit disk layout" allows you to manually resize/move partition layout on this destination disk.
Tick the "Check the option if the target is SSD" option to put your SSD in its best performance.
A message now appears, warning you that data will be lost. Please confirm this message by clicking "OK" and then click "Next".
Step 4. Click "Proceed" to officially execute the task.
