Since the site shows the My Book unit (WDC USB drive) is consistently

used inside of it? The model number for the unit doesn't give the model
number for the drive(s) inside of the unit. The unit is only spec'ed
according to its capacity, not the drives inside. At 6.73"x1.93"x5.47",
maybe inside there are two 2.5" drives or even four 1.8" drives.
Nope, just a single 3.5 inch drive. I am sitting here looking at one.
I can see the drive plainly through the top air slots and there is
only one drive. But I cannot make out the drive markings without
removing it from the case. And it is the new WD case.
Darn. Would've been nice to know what they actually used inside for the
HDD. Couldn't find anything about the HDD itself at the WDC site or in
online reviews. It's probably a snap-together case so trying to open it
means probably breaking a seal along with some tangs holding the two
halves together.
Is the side you can see through the case slots colored red, blue, black,
or purple?

This guy dismantles the case to look at the drive inside.

That review dismantles the case, too, to look inside.
That has the smooth case wherease the link you pointed at has the
textured case. Don't know if it makes a difference other than the
feature fluff they add with different models. The HDD inside is not
marked like a red-, green-, blue, or purple-labelled HDD from WDC.
The WD80EZZX (the model number shown on the internal HDD) in the My Book
is a 5400 RPM unit. I thought Reds, being used for NAS storage and
targeting business users would be 7200 RPM drives. Nope, they are just
5400 RPM - *unless* you get the Pro model of reds.
From those reviews, and because of the low noise, it looks to be a 5400
RPM HDD - but then so is your first link to the bare red HDD. This
isn't surprising since many pre-built external USB drives are 5400 RPM
to reduce heat and noise but also the gyroscopic force should the user
go mauling the unit while it is running.
The white label 8 TB HDD inside the USB case is made by HGST. It is not
stamped as a WDC drive. HGST is a wholly owned subsidiary of WDC. The
red drives from WDC are marked as coming from Malaysia whereas the
unknown HDD inside the USB case is marked as coming from Thailand. So
from neighboring countries but clearly indicates different manufacture
plants. I've owned both WDC HDDs and HGST HDDs with the latter used in
my laptops. Seems they are equivalent regarding quality and durability.
When I go to newegg.com, the 8TB HGST HDDs are generally more expensive
than the 8TB WDC reds. That's because the HGSTs are 7200 RPM versus
5400 RPM for the WDC reds.

I only saw 7200 RPM units mentioned there. Maybe HGST has forayed into
5400 RPM units at 8TB as a special production by WDC. Too bad the guy
in the 2nd article didn't compare the benchmarks for the mystery
WD80EZZX inside the USB case against a WDC red-marked HDD. However, he
would've had to take the WD80EZZX out of the case so he could hook it up
to the same controller using the same interface (no USB conversion
between HDD and mobo) to do a proper benchmark.

That lists some benchmarks for comparison. Benchmarks are rare for this
unit to compare against other external and internal HDDs.
So the biggest difference looks to be as to which market the units
target. The USB drive is more like something consumers would want. The
internal red HDDs more target business deployments.
The drive inside appears to be white. No color.
It is not extremely fast. I am writing a LAN backup to it right now. About a dozen PCs of around 3.5 TB. Not fast is ok, I just
write to it once every seven weeks (rotating external drives written on each Friday night). The three internal backup drives get
written each night.
