It's a bit old but I came to remember that I had a question on non-standard RAID implementations, which got shot down for being non-constructive. I do not agree with that assessment and would like to have a short discussion about it. I believe the question is not a shopping question, and it's not very subjective either. I am not asking for which one should I buy, or which one is better. I am interested in pros and cons of each system.

So, to re-iterate my questions:

  • why is this question considered not constructive?
  • if it really is not constructive, how can I salvage it to get some insight on the matter?

EDIT: To stress my claim; please take a look at this question and tell me how it's any different: Which linux filesystem works best with SSD

  • The current version of the questions seems like all any answer would be an extension of a discussion which makes it not very constructive on a Question and Answer type format.

  • The problem is you're trying to get a comparison of very obscure, specialized RAID implementations, each designed for a fairly specific purpose. I think the creators of each RAID level provide more than adequate information for you to compare them yourself, for your particular use. Commented Feb 28, 2013 at 21:40

  • @OliverSalzburg mostly on StackOverflow ^^. I was frustrated when the closing happened, so I wanted to calm down before writing about it, then I must have forgotten about the question. As I said I dont want to complain about the closing decision, I just want to know whether or not I can't salvage something out of that question

  • @posdef If it were me, I'd remove the junk about why you're buying it, it's not relevant. You would also need to explain what is not clear; what, after reading the Wiki link, was still unclear. This then becomes concise but as it stands it's a very open ended question IMO

  • @posdef - You are right there is little difference between the two questions. Just because you found an open question with lots of upvotes doesn't mean its a good question. It was also migrated to Superuser instead of being created on Superuser.

  • This is a question that I had on laptop battery tech when I needed to buy a new laptop battery. Feel free to use this as an example on how to ask such questions. Commented Apr 5, 2013 at 16:02

You could salvage this question by wording it as "What should I look for when considering proprietary RAID implementations?" and removing the references to specific NAS systems.

As it stands, your question is specific to a particular set of NAS/RAID systems, which tends to draw opinions in favor of or against a particular system. This is why your question was closed as "not constructive". In addition, this is very similar to a direct product recommendation question, which is considered off topic.

In essence, you should be asking for how to find the product that suits you best, not what product to buy. This quote sums it up:

Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime.
