Well, the server is not really near my location. So, if I have to drive
there every time to replace one disk. Replacing 2 at a time saves me
time to drive there. It will most likely not speed up the process.

It will become an array of 10 4TB disks. Which is not my favorite
setup, but then again, it only has to run like this for a couple of
I might be wrong, but if I do a scrub before starting the replace with
2 disks, the changes of encountering a checksum error during the rebuild
are pretty slim. The data is backupped so in case of total disaster I
can recover again.
The thing is, I could do just recreate the pool with the new disks, and
recover everything from backup. But that will cost me 24 hours of
downtime. I'm willing to take a chance. I might be lucky, or I might
have my downtime anyway.....
