You can't compare models if only 1 has a discount or rebate.  Just
because a store has a rebate on one model of a maker's product doesn't
mean there is a similar percentage rebate across the entire line of
products or for every product by that maker.  You know how rebates work.

So, using the $199 non-rebated price ...

The desktop internal drive is $50 more.  Alas, no mention of RPM for
either model.  That's typical with external pre-built drives (they want
you to focus on portability and bundleware, not performance) but
internals should mention RPM.

The datasheet for the external (could only find 4 TB) at:

http://www.seagate.com/www-content/product-content/backup-plus-fam/backup-plus-desktop-drive/en-us/docs/backup-plus-desk-ds1757-2-1306us.pdf

has NONE of the specs you find in the datasheet for the internal model,
which is at:

http://www.seagate.com/www-content/product-content/barracuda-fam/desktop-hdd/_cross-product/en-us/docs/desktop-hdd-ds1774-5-1506us.pdf

With the external, you don't what the phuck you're getting; however,
Seagate doesn't divulge the RPM for their internal model, either.  I've
read elsewhere the internal model spins at 7200 RPM.  Unless you void
the warranty by opening the external's case to see what drive model is
in there, you don't know what it is or how it compares to the internal
model.  To reduce heat, power consumption, and noise, the external model
probably has a 5400 RPM disk.  I suspect you would find benchmarking
shows the external is laggy compared to the internal model.  Capacity is
not the only differentiator between HDDs.
