Yes it is but the Raspberry Pi OS I botted up in the Virtualbox is a lot
more responsive than my actual system it is running on.
I am still trying to figure out the reason why ? If you ever had a  Windows
machine and you installed Linux on it then you know what
I am talking about. Same hardware just running Linux now instead of Windows
and the increase in speed and performance has to
be experienced to be believed.

Never said obsolete said ancient . I am happy with what I have and it
was William
Witteman who reached out and sent me the $:$$
when I was pulling my hair out many year sago because six hours had elapsed
and my kernel was still not done compiling. I had a
Pentium II back then. So nothing wrong with my system I just need a Pi for
different reasons.

I am scared of SSD's for a good reason. They have no early warning system.
And when they decide to fail omg they fail so beautifully.
Beautifully equates to catastrophic unrecoverable as in dead in the water
so uh-uh I will stick with my old hard disks. I can hear them rattle and
diskmonitor gives me so far very reliable indicators of disk health.

True !

Still compiles the linux kernel in just over 30 minutes sometimes 20
minutes.

Well like i said before the responsiveness of a given system is a  very
tricky thing. The Raspberry Pi OS running in Virtualbox is way faster
when I click the app opens real fast boom! This may not happen on the real
hardware I have t wait and see once I get my hands on one.

I have  8gigs RAM.

SSD for me is a no-no. Risk of failure with absolutely no prior indication
is a risk
I am unwilling to take.

Thank you Hugh very much appreciate all the digging and time you have spent
on my account but
what I need right now is a paying project or some sort of stable work I can
do remotely. I am not
complaining or bitching but 15 odd year snow in Toronto I am yet unable to
securer any computer work.
All I have is a minimum wage call center position. Which I am happy with as
I have friend's who have no jobs right now.

If anyone has any work that is within my limited skill sets please do send ?

Yes I am very much keeping my HDD.

Thank you very much for all the info Hugh.
