The other drives I've transferred to are older drives, for example a 3.5" WD Black 1TB, 3.5" WD Blue 1TB. I know that all the drives I'm using are capable of at least (sustained) 100MB/sec write. The only other things I can think of trying are another enclosure and another USB3-HDD cable, but I'm doubtful of either being the cause since no errors/warnings are being reported in dmesg. I saw that another kernel update was due in Update Manager so I let that run and then rebooted but it hasn't helped. I'm pretty sure kernel 6.2.x didn't have this problem.
Is anyone else seeing similar issues?
- edit -
I've tried two enclosures (one has a molded USB3 cable so different cables too), set up a test and here's the results, both enclosures to my fastest drive showing extremely variable transfer rates:
