However the problem remains (unchanged) - I have switched off book details as well, no cover browser etc but still -
Any ideas from the community please?

Changing metadata, causes quite a few places/files to be updated.

As theducks mentioned, SD cards have pretty slow write speeds (Class 10 is just 10 MB/s). My HDD has an average sustained write speed of 80 MB/s (min ~60 MB/s, max ~100 MB/s) and my SATA II SSD can do over 150 MB/s. That's just talking about sustained write.
Calibre database operations are probably more akin to random read/write performance in which case, a Class 4 or 6 card from a good manufacturer (e.g. Sandisk) might work better than a Class 10 card from another.
