I voted to close that question as Not Constructive.
The reason?
The actual question you asked was
what would some of the benefits be of moving to a more robust platform?
Which in my mind, ticks all the boxes of the reasons I've highlighted above.
...and I've also voted to close the SAS/SATA question for exactly the same reason.
For what it's worth though, I do agree with your point about how you think questions of this nature should be left open as they are interesting and beneficial to us. But the description of Not Constructive, fits both of those questions and hence warranted a close vote IMO.
With regards to your specific question, there isn't one specific correct answer to your question. There are multiple correct answers that might not be covered by any one response to your question, but that doesn't mean other responses will be incorrect, which to me is 'polling'. You might need 4 or 5 responses to get a full picture of all the benefits (extended discussion), one admin's perceived benefit might not be as highly valued as another admin's, (solicit debate). So I stand by my reason for voting as not constructive.
