I agree completely. I mentioned I initially thought RAID-5 provided the better capacity:redundancy ratio so I went for that. If performance wasn't in issue, that'd still be my first choice.
I'm only intending to use the RAID as an extra backup. In other words, I'd regularly replace bits that have changed and write whatever is new. If all went well, in theory, I'd never need to read anything back. The only time it'd be in use is for write operations.
And this backup set includes VMs that I need to keep running most of the time. The performance I was seeing with RAID-5 made that impossible.

Of course RAID-5 has terrible write performance. That's practically its purpose.
I've seen SQL Server installations that had one gigantic (by the standards of the day) RAID-5 volume to hold everything.
I was able to improve performance by a significant amount (2x?) just by fixing that stupid configuration.
This was 20+ years ago so some of the details are a bit hazy.

Thank you for your timely, constructive input.
I've since come to the same conclusion.

I'm crylaughing at myself. I forgot how to enforce operator precedence in parsing code.
I've written it countless times. I have no idea how I forgot. It should be practically muscle memory at this point.

Any operator who slips you a twenty gets precedence.

Thanks, but I can write a grammar for it. I just forgot how to write the code. :P

Not clear on what happened.
Did you forget to put operator precedence enforcement into the program, or did you forget how to implement operator precedence enforcement?
The difficult we do right away...
...the impossible takes slightly longer.

Sadly, I came to this thread to read about bicycles I recently acquired a Circus Bike and that will make you feel like you truly can't ride a bike! Now back to your regularly scheduled programming.

You forgot what parentheses are for?

No. This isn't about constructing an expression that overrides precedence, but rather properly evaluating an expression with proper precedence.
