It is not possible to transmit large amount of data as one single file (30GB) or multiple files from any source (even from the virtual drive itself) to the virtual drive. Transferspeed recurring breaks down to zero.
Besides i tested with an external hard drive as target and get constant Speed. So it seems to be a problem with StoreMI.
I tried to disable 2G Ram cache and rebooted but i still have the same issue. While tansfer speed breaks down, the virtual SSD ist still 100% in use (see Screenshot). In this state other simple writing or reading tasks like saving or opening an jpg image take many seconds. The ongoing copy task literally stops too. (something between 0-4 Mb/s)
It can not deliver constand performance. I am using a Samsung 970 EVO NVME 250 GB SSD as fast drive and 4TB Seagate Barracuda Compute in addition.
Thanks for your help!
