Boot Mode: UEFII just took ONE WEEK 24/7 to rsync 65 GB to the Kingston flash drive given in above system info, plugged into a blue "S/S" usb port (avg tfr rate ~ 0.5 MB/s).
Then I tried the echoes to /proc/sys/vm/dirty... suggested near the end of forum topic "USB transfer speeds slow/ data needs to be written" . It increased the speed to 13.5 MB/s for rsync on a single .deb file. Unfortunately when I did the same rsync transfer with the default values (dirty_bytes=20 000 000 dirty_background_bytes = 0) it went at 7 MBPS. The multiple file transfer is apparently 10x slower than a single file.
13.5 MBPS still sucks. Claimed transfer rate for this USB3.2 Gen 1 drive is 5 GbPS ~ 600 MBPS. It is a factor 40 slow. Later in the week I will try the same drive on a Windoze machine at work and report the result here.
Does anyone know whether Kingston flash drives are slow? I don't do this often enough to spend a lot of time and money trying different brand name drives and some earlier posts suggest that's a waste of time anyhow.
ANy other suggestions welcome.
