When running Opensuse on a 64 Gig Flash Drive, it has frequent lockups lasting 5 -10 seconds at a time. I have 10 Gig of free space. Is this normal for a Flash Drive? Could it be the USB system?
Hi and welcome Master_Rod,
I’ve never tried that before, but it doesn’t sound correct to me.
I don’t believe it’s an openSUSE specific issue. Have you tried to figure out the IO utilization while your read/write freezes?

Other possible reasons:
USB powered down from lack of use - add usbcore.autosuspend=-1 to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub
USB 2.0 Flash Drive - go to a USB 3.0 Flash Drive - most are 3-4 times faster.
BTRFS used rather than less complex EXT4
Too many file systems - install with 2 or 3 file systems - 1 fat16 for UEFI boot, 1 swap (same size as memory or a little larger), the rest of the drive ext4 for /
I have no problems with Samsung and SanDisk USB 3.0 drives that are 32GB - less than 50% full - some are UEFI and some Legacy Boot.
I use them on old Dell D820 and D830’s that have no drives - works good enough for browsing the internet and running vlc and libreoffice.
