Irrelevant to the dBA and Bel.
That particularly 'fact' is irrelevant to the point he made.
Nope, its all what you can actually hear, in the end.
The samsungs are noticeably quieter than the WDs.

Gosh you have had some bad luck.
I have put WD drives in various machines for friends over the past few years
and never had a problem. I have 4 in use myslef (WD1200JB, WD2500JB) since
they first came out - so thats a few years now.
And you currently have a problem with backing up the
partition over 10G which could well be a drive failing.

That still has nothing to do with bel and decibel. A dB
is a tenth of a bel. However, it may be that WD is using
SPL (not noted by WD; could be PWL) while Samsung says it's
using PWL. Nevertheless, a Bel is still 10 dB. Your
argument is sound pressure level versus sound power.
http://forums.silentpcreview.com/viewtopic.php?p=167623#167623
Notice in this web-snatch (bottom) that either is expressed
in, and I quote, "decibels" (dB). Bel is arcane, and
obviously not commonly (used outside of some HD makers'
specs). Consider a PS fan; these usually run 40 to 50dB
at 1m, and CPU fans easily louder (typical AMD fans are
70 dB). You'd need a several dozen HDs all running together
to reach that loudness: 30 dB + 30 dB = 33 dB (SPL). + 30 dB
+ 30 dB = 36 dB (i.e., two pairs of 33 dBs are 3 dB louder
than the one pair), and so on.
Sound POWER Level (PWL):
The sound power of a source is the total sound energy radiated by
the source per unit of time. The Sound Power Level (PWL) of a
sound source describes the power of the sound radiating from the
source. The PWL is expressed in decibels and is dependent upon
the number of watts to which the source is referenced.
Reference power level is 10(-12) watt.
Sound Pressure Level (SPL):
The sound pressure is the instantaneous pressure measures in a
sound wave; i.e. the variation from atmospheric pressure. The
Sound Pressure Level (SPL) of a sound source is a measurement of
sound expressed in decibels at a specified location. The SPL is
dependent upon the sound source PWL, the distance from the sound
source and the environment around the sound source. The PWL of
the sound source remains the same, but the SPL decreases
approximately 6 decibels for every doubling of distance from the
sound source.
Reference pressure = .0002 microbar

To say it again, your argument should
be the difference between PWL and SPL,
not Bel versus dB. A Bel is simply
10 dB, nothing more, nothing less.
However, Bel is arcane, as is sound
power level. WD is using the better
of the two (SPL), since SPL is easy
to discuss (well, for some -- haha).

I agree that a 1 Bel = 10 dB *if* they're measured the same way.

That's a non sequitur. That's like saying a liter
is 10 deciliters only if they measure the same
liquid. It makes no difference; it's a tenth of
a liter.

Measurements of volume are some what different in nature from measurements
of energy.
Measurements of energy vary significantly depending on methodology.

You're still confused. 2.6 Bel is 26 dB. It just happens to
be another scale (dB doesn't even have to apply to sound
at all). However, more so, and still, you are befuddled by
this since you cannot support any sort of argument about
which is "quieter". I can easily argue that it doesn't
matter, because 26 dB (A-weighted, or whatever) is, for all
intents and purposes, -silent-, easily droned out (masked)
by ANY other system fan. It would take more than a dozen,
active, seeking WD 200GBs to be as loud as the quietest PS
fan (40dB, most are over 50 dB). Throw in an AMD CPU fan,
and you'd need several dozen, perhaps more than 100 (easy
enough to calculate if you want to do it) or more drives all
running. It's marketing, that's all it is. And, of course,
you can't even get a 200 GB disk from Samsung, so it's sort
of moot. You're a victim, like many, of marketing -- you
believe because Samsung puts some "2.8 Bel" sound power
level (which, by the way, no one can verify) that this is
somehow magically quieter than silent. (LOL) Everyone
has a sound pressure level meter, so WDs specs can easily
be verified. Who are you going to believe? I leave that
for you to ponder, but the answer doesn't matter to me.
Happy drives!

As I've already said my CPU fan is rated at 22dBA compared to 35dBA for each
of my two drives.
The rear system fan and PSU fans may be louder, but they're a lot further
from my ear than those three fans.
I can hear my drives idling, let alone seeking.

Nope.
If they measure the liquid *the same way*, i.e. under the same conditions.
But only at the same temperature and ambient pressure level.
Change that and -even with the same type of liquid- results will be different.
Measurements of volume are some what different in nature from measurements
of energy.
Measurements of energy vary significantly depending on methodology.
Only in their expression (unit of energie, s.a. hp, Watt, Bel, Phon etc).
