Reliability of 500GB PRT hard disks?

The Seagate 7200.10 consumes about 50% more power than the 7200.9
(12W instead of 8W). Could this have any consequences for waste heat,
and hence reliability?

I have searched both the web and usenet for feedback on the Samsung
T166 (9 watts), but found nothing. It runs 4dB quieter and 30% cooler
than the Seagate 7200.10, but only comes with a three year warranty.

Is it too early to make any meaningful comparison of the reliability of
the latest 500GB hard disks with prependicular recording technology?

If cooling is inadequate, yes. The .10 drive will experience 50% more
temperature increase, compared to .9 drive, given some airflow.
But with reasonable airflow, it should still not be a problem.
Were are the power figures from?

Don't mind the warranty. 3 years is plenty. Personally
I like the Samsung drives.

The Seagate web site.

7200.9:
www.seagate.com/cda/products/discsales/personal/family/0,1594,704,00.html

7200.10:
www.seagate.com/cda/products/discsales/personal/family/0,1594,746,00.html

Although these tables give, for example, the average power consumption
of the 500GB 7200.9 during seeks as 8.161 watts, the details in the
product manuals:

7200.9:

7200.10:
http://www.seagate.com/support/disc/manuals/ata/100402369a.pdf

give the power requirements of both as 12.6 watts. Sorry for the
mistake.

The Samsung web site gives the corresponding results for their drives.

Corse it could, there is nowhere else for that power to go.
and hence reliability?

Depends on how well its cooled.

There's quite a bit in the storagereview reliability database.

Some very interesting differences with the different Seagate models too.

Yeah, so far only Seagate has gone for 5 years
with the mass market commodity drives.

Yes. All you can see currently is the infant mortality, and presumably most
of that is user stupidity, not cooling the drive at all, and dropped drives etc.

So basically that is the maximum sustained power consumption
after start-up? Then both are the same. The .10 might be a bit
better through better optimized accesses or not.

For a server, I would go with the seagates. For home system
with samsung. They really stay quite cool. Only problem
I have observed with Samsung is that they vibrate. It is
inauduble with one disk, but with two, you can get a
slow WAWAWAWAWA-like sound from interference ...

Next disk I will be trying is the Seagete ES drives, They
are suppised to be selected for low vobration and are
only marginally more expensive.

Are you talking Kelvin or Centrigrade? ;-)

Yes! What is 50% hotter than 40 degrees Centigrade. Brings to mind a
question I got wrong on my physics 101 final oh so many years ago.

Hehehe. I wrote ''increase''. And one increase being larger than the
other. That gets a full score ;-)
