Thank you all for your responses on and off list !
The short answer is:
Yes it's possible to mix different HDD speeds, but the server may
experience some micro-freezes when the different caches flush out.
In this particular case, the time to wait for a true replacement HDD was
too long and I feared a second HDD failure on the RAID5 array. So I needed
to put a HDD in as soon as possible.
Have a nice day,
