In one test, a WD SN850 SSD plugged into an M.2 slot controlled by the AMD X570 chipset experienced a decrease in performance.
There is an interesting report regarding the compatibility of WD’s SSD with the AMD X570 chipset. Reportedly, users experience a decrease in performance when using this combination.
Tom’s Hardware (June 17) reports that a test conducted by ComputerBase showed a significant decrease in performance when they used the SN850 SSD on an X570-based motherboard.
This condition is found when users use the M.2 SSD slot directly connected to the X570 chipset. Meanwhile, when the user uses the M.2 SSD slot connected to the CPU, there is no problem.
In the write speed test, the SN850, which uses the M.2 slot connected to the CPU, speeds up to 5,254 MBps. When connected to an M.2 connected to the X570 chipset, the speed drops to 3,247 MBps.
Typically, the difference between an SSD connected via M.2 to the processor and the chipset is a maximum of 10% difference. However, the difference they get can even reach 43%, which will greatly impact the users.
Surprisingly, when using another SSD, this problem is not very noticeable. WD is currently investigating the location of the problem. Hopefully, they can resolve this issue shortly. – WD SN850 SSD
