No, not any more. Those configuration details come from HD-based server
systems I constructed many years ago. My new prototype to which I'm
migrating my main linuxmafia.com AKA unixmercenary.net system dispenses
with spinning rust entirely, in favour of a RAID1 pair of SSDs. Good
riddance to spinning rust (except for high capacity and ancillary
storage, of course).

It's not just _performance_, though, but also longevity. The hard
drives in system I construct in the manner described tend to last quite
a lot longer.

It is indeed important. I didn't mention that because it had no
application to the discussion we were having at that moment. (I'm a
huge fan of md-driver RAID1.)

Yes, and this is in my opinion a very regrettable omission from the market.
Many laptop enclosures have adequate physical space for a pair of
equal-sized SSDs. If they would only please leave an empty bay for a
second device and unused power and data connectors, I would be happy
with the option of RAID1-mirroring the entire system.

Worse, some lovely small systems like the Zotac ZBOX C-series, likes
this one as a current example
(https://store.zotac.com/zbox-ci325-nano-with-windows-10-zbox-ci325nano-u-w2b),
would make great little silent home servers, except that they support
only one 63.5 mm (2.5") SSD plus one SSD in the M.2 slot. Grr, so
close, and yet so far.
