Fulfill the promise, Western Digital deployed new firmware for the company WD black SN850 SSD, currently one of them The best solid state drive in the market. When the drive is installed in the M.2 socket connected to the AMD X570 chipset, the latest firmware will restore the write performance of the SN850.
SN850 is currently one of the fastest SSDs.However, the user reported a Performance loss exceeds 40% If the SSD is located on an M.2 socket that does not directly communicate with the Ryzen processor. We believe that this issue will not affect users who use SN850 as their primary drive. But for users who have multiple SSDs and SN850 connected to the AMD X570 chipset on the M.2 socket, this may be a big problem.
According to Western Digital, the problem is related to the maximum payload size (MPS). When the MPS option is configured as 128 bytes, the performance of SN850 will be affected. Western Digital’s new firmware (613200WD) seems to have solved this problem, although we don’t know how this firmware has changed from the previous version.
MichaelMros from Computer base The forum pointed out that Western Digital has completed the repair. Using the previous 613000WD firmware, the upper limit of the sequential write performance of the SN850 is 2,821.63 MBps. On the latest 613200WD firmware, the drive can reach 5,115.11 MBps. Other numbers are within acceptable limits.
The new firmware is only available through the Western Digital Dashboard software. All you have to do is to start the program and it will prompt you to update the SN850 firmware. If you do not receive the notification, just reinstall the software.
