As mentioned in release notes, if ssd speed is bad or after lots write without trim , file write will fail. clean up your SSD and do "sudo fstrim /your_ssd_driver" will solve this issue. If you using GPU plotter, the speed requirement for SSD even higher. QLC ssd need two as raid0, or use good speed MLC ssd.

the best practice is: for tmp driver, move out plot after done and make sure it's empty , then do fstrim . then SSD speed will back to normal for plotting.
