Yes, indeed, I'm with you on that. Market is driven by low budget
(ignorant - not to offend, but to just qualify in insight into hardware)
consumer. Which indeed leads to "fake raid" chips (aka "software" raid),
and many other bad things. I sometimes have to deal with what students
have ordered themselves. Hence excessive attitude. As they order before
they hear from me: "pricegrabber is an enemy in choosing reliable
hardware". Then all leads to downtime, someone has to spend time on
repairing the darn thing. Whereas, if one pays mere 15% more and gets good
hardware, future losses (including human time which is very expensive) can
be avoided. Alas, SSD difference in hand is larger that 15%, hence
probably nobody will dare to help with advice. If there is good advice
that is. I for one did go with Samsung SSD...
