[AFMUG] OT: Why are External Hard Drives so Cheap?

[Nate Burke]

Why does it seem like the $/Gig are way less on external drives than 
internal drives?  Aren't they basically a regular hard drive in an 
enclosure?

Best Buy has a 3tb External Drive with Ethernet (they call it a NAS) for 
$80, Cheapest price for a 3tb Internal Drive on Amazon is $85

4tb External Drives are $90, Amazon has Internals for $130
