I really think the foam (memory foam??) is one of the keys to how quiet this unit is.

My HR21-700, which has no foam, is silent as well.

As is mine. They're basically right next to each other (-700 & -100) and I can't hear either one even when right in front of them with nothing else on.

I'm sure Directv can't wait to get their hands on your unit.

I can't hear my HR21-700 either. It's just the "idea" of the foam that I like. :)

Great job as usual guys.

I'm intrigued by this statement within the report:

"The HR21-100 runs silently, even in the quietest of environments. The interior fan is barely audible, while the hard drive is completely silent."

Seems too good to be true. :) I definitely need to somehow swap my HR20-700 with the HR21-100. Currently, I have to unplug my DVR every night just so my wife can get to sleep.


As others have said, this is the truth. The HR21 is almost silent compared to the HR20. Heck, my HR21 is even quieter than my R15's now that I think about it.

I guess I have no clue what the foam is for....:rolleyes:

When I was taking the pictures my daughter wanted to steal the foam.

Something about keeping a makeup something or other from sliding across the table.

So I guess it has some use...:grin:

I wonder what it actually does. If not for sound/vibration isolation then what? I suppose it could block air flow above the drive or vibration protection during shipping.

My guess is that it's both air flow management and to reduce vibrations. Does the foam touch the cover when it's attached?

I do find it a bit puzzling as the hard drive is the biggest heat generator in the box. Normally the last thing you'd want is to put an insulating material against the largest radiating surface of the drive.

It fits exactly between the drive and cover and it is an interference fit.

That's why I thought it must have something to do with sound attenuation.

Definitely an interesting quandary...:grin:

I can tell you it wouldn't likely be memory foam, as memory foam is a lot denser and probably would impede heat dissipation.

I'm curious what brand/type/speed of memory this device has. I couldn't zoom into the picture enough to get a clear view. Are the original pictures high enough resolution to make out a part number? I believe the memory is the row of 4 chips just to the left of the processor.

Truthfully I don't have any idea what it really is. :shrug:

Here's a little speculation not necessarily based in fact...:scratchin

I have a sample of memory foam I got at a home show. It is identical in feel, weight/density, and color to the foam in the HR21.

Memory foam has a very weird feel to it. The surface has a kind of oily/sticky feel to it. It is because of the similarities that I think it might be memory foam.

Heat has always been a problem with memory foam. There are some composites and re-formulations that are supposed to be better at dissipating heat. Regardless of composition, the one in the HR21 certainly denser/heavier that the standard foam pad. Not that it matters. Any foam pad will provide thermal insulation. However, the fan is right up against the drive and will easily control the temp in the drive.

It's just an incrediblely weird place for any kind of foam pad. It can only have a limited number of functions...insulation, air flow, sound, or vibration. IMHO it can only be for noise or vibration with an outside chance of air flow control.

It's a theory. :grin:

Thanks guys! That was fast.
Strange though, the parts look to be EOL. That can't be when this is a new device. Also, these are 512Mb, which means 4 of them totals 256MB. Maybe there's more on the other side.

Thanks for the warm welcome.

again the latest write up shows its "cooler" than its "brothers" by running between 105 and 115 degrees....my HR21-700 has NEVER been over 115 degrees and is usually around 110...and i have a time warner sa8300hd box sitting on top of it...so again, how this new one runs any cooler is beyond me when the internal temps are the same. the fan in my unit is also whisper quiet, quieter than the sa8300.
