This firmware update was released to address the speed drop issue when the WD SN850 SSD is connected to the M.2 slot connected to the X570 chipset.
After promising to make a firmware fix a few weeks ago, Western Digital has finally released the latest firmware for WD SN850 SSD users. This update will fix the speed drop issue in motherboards AMD X570.
In several trials, it was found that the speed of the SSD SN850 will decrease drastically when using the M.2 slot connected to the X570 chipset. The performance of this SSD is also reported to have reduced dramatically from the standard in the range of 10%.
Users say that the WD SN850 SSD gets a performance drop of more than 40% when connected to the M.2 slot connected to the X570 chipset. For users, especially content creators, this is a big problem.
Another thing when the SSD is connected to the M.2 slot connected to the processor, which will run at full speed. And if this problem is not addressed, then the user will feel very disadvantaged.
Tom’s Hardware (July 13) reports that Western Digital’s new firmware (613200WD) appears to have fixed the issue. Some say that Western Digital has improved the sequential write performance of the SN850, just being limited to 2,821.63 MBps.
On the latest 613200WD firmware, the drive is capable of up to 5,115.11 MBps. The other figures are within acceptable margins. To update, users need to open their Western Digital Dashboard application.
According to Western Digital, the problem with this performance degradation has to do with the maximum payload size (MPS). This causes the WD SN850 SSD to experience a performance hit when the MPS option is configured to 128 bytes.
