RPI3B+ UFS filesystem issues

[Stefan Parvu]

Are these signal of troubles form the filesystem layer ? Im using a Transcend 64GB 
https://fi.transcend-info.com/Products/No-697. Dont know if I can benefit from this
card of its full speed on RPI3B+ .

Im using FreeBSD 12.0 current latest 28 June snapshot:
