Micron is definitely still in business:Where did you see this recommendation? I looked at the tested memory list and I only see Hynix, Samsung, and Micron. Maybe you have a link where they recommend this? I'm searching the FreeNAS forums to see if anyone has been able to use any other memory not on the tested list. I know very little about the tested ones. I am unfamiliar with Hynix and thought Micron went out of business years ago. I'm leaning towards buying the Samsung modules at this point.

and, having bought Elpida, claims to be one of the only three major RAM manufacturers in the world, the other two being South Korean (presumably Hynix and Samsung).
