The Transcend ssd is formated ZFS, I use it as a backup.

The microsd might suffer from what you say since it's formatted by Android
but I do not get these slow transfer speeds on other OS.

so a quick roundup.
1) 256GB Samsung microsd card gets 7-8MB/s transfer speeds;
let's say that's because of the Android OS default format.
I only get these slow speeds on FreeBSD, why is that?

2) 1TB Transcend SSD formatted to ZFS I pasted the dmesg log above;
are the slow speeds user error or something else?

@Warner Losh
what was your setup where you were able to transfer 23-75MB/s to your USB
device?
