how should a hard disk work? Data is written, data is read.
How should this SSHD know where by boot-related data is stored? Why
should this disk waste SSD memory for data I need with FreeBSD very
It does not seem to me that it is like this. It is more likely that it
uses the 8GB as a write cache. It is very fast before 8GB transfer
volume is reached. If I copy a lot, the write speed goes down to 15MB/s
