How Much Faster Is NVMe SSD Than SATA SSD

I want to buy an SSD for my PC. However, many types of SSDs make my decision difficult. NVMe SSD and SATA SSD are what I want, and I want to choose one SSD with a fast speed and a relatively low price. So any suggestions? How much faster is NVMe SSD than SATA SSD?

NVMe, or Non-Volatile Memory Express, is an ultra-fast way to access non-volatile memory. It can be about 2-7 times faster than SATA SSD. Brands with different capacities have different read and write speeds of NVMe. NVMe has up to 64,000 queues, each capable of handling 64,000 commands simultaneously!

When we talk about superior storage technology, NVMe is in a class of its own. Even at first glance, the difference in performance between NVMe and SATA is impressive. The communication drivers and interfaces between NVMe and SATA are completely different. SATA uses AHCI drivers for hard disk drives (HDDs) with spinning technology, while NVMe drivers are designed for SSDs with flash technology. Additionally, NVMe is able to utilize PCIe slots for communication between the storage interface and the system CPU for greater utilization. You can use third-party software to test the speed to determine which one runs better on your computer. EaseUS Partition Master can test NVMe/SATA/M.2 SSD read and write speed.

Here is how:

Step 1. Download and launch EaseUS Partition Master, and activate the "Disk Mark" feature in the "Discovery" section.

Step 2. Choose the target SSD and set the test data.

Step 3. Click "Start" and wait for the process to finish.

This way also applies to test speed for Steam Deck SD cards, SSDs, external hard drives, hard drives, and USBs.

Besides, when your SSD slows down due to full capacity or long-term use, you can use the "4K Alignment" feature of EaseUS Partition Master to improve its performance.

Hope my answer can help.
