How to Choose Between 2 SSDs

With most of the specs aligning, it's a hard task to choose one. Surprisingly, there are a lot of benchmark factors that can confuse you regarding SSDs. Here are our suggestions on which SSD is good for what.

The Samsung 990 Pro is definitely the fastest of all the SSDs. The writing and reading speeds are considerably fast and are best suited for people who want consistent high performance. It's great for editors, graphic designers, and gaming. You can render the graphics, load the games, and edit videos of high quality much faster. If you want to run your PC to churn out consistent performance, the 990 Pro is the best. The hardware build is extraordinary considering the read and write speeds, but if you want to buy one, you should take one with the heat sink to avoid failing for intense workloads.

When it comes to the WD Black SN850X, though it lags by a slight margin for reading and writing speeds, surprisingly, the PC Mark test shows that it has much faster loading, processing, and rendering when it comes to gaming. This one also has a PCIe 4.0 interface, which works great for high performance and less latency. If you are into gaming and in need of an extremely high-performance SSD, the SN850X is the absolute best. Out of all the benchmark tests, this one gives you enough power to run everything smoothly. Be it for editing, gaming, or normal usage, and if you have budget constraints, SN850X should be your choice.

To conclude, what is best of the two depends on two things. If you are an editor, designer, or anything that needs consistent performance, the Samsung 990 Pro has no competition. And for Gaming, the obvious choice has to be WD black SN850X. But if you have budget constraints, SN850X can do the job smoothly, except on a little slower side. If budget is not an issue, I personally think you should not look beyond 990 Pro for anything. With such sequential read and write speeds, even high-end gaming is a cakewalk for Samsung.
