For me the answer for this is: use what you need. For example consider raid. On my desktop I have an mdadm raid level mirror. It is only a desktop used for some task at home (testing, coding...). Why buy a valid controller like areca or (as suggested on a discussion, maybe on reddit) an HBA to make a simple raid? I don't need an HBA or an high value controller on my i7-2600k. Then the consideration should be "if you need high disk I/O perfomances and a lot of space buy the right hardware." For example there are a great number of small offices that need of little nas. There are cheap products that can perform well this operation but these are not valid hardware. I'm not a fan of this solution types but many technician install them because the committent says "oh please, drop the price". If for a small office, a technician must get a 1000/1500 $ for a server to serve as nas, he will not work. I have seen this type of product on lan with 120 hosts with a deadly performances.
