The WD Red drives caught my attention, but the official
documentation<br>
<br>
<a class="moz-txt-link-freetext" href="http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-771442.pdf">http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-771442.pdf</a><br>
<br>
lists the rotational speed as "IntelliPower" which is not a float.
I suspect they play a game similar to the Green drives which your
RAID controller may/not enjoy.<br>
<br>
Definitely, for production purposes (other people's bits),
Constellations (SAS) or RE4 drives are the correct answer. That
said, I have not seen WD Caviar Black disappoint over dozens of
drive-years for people wanting to save a few bucks and still have a
5 year warranty.<br>

NAS/server purposes, which would be the equivalent of WD XE, RE,
or RE4 series drives (XE and RE SAS are 2.5", and RE4 units are
3.5"). Sometimes I substitute a Barracuda (which I see as an
equivalent of the WD Black series).<br>

Canada Computer and such -- in order to get the cheapest possible
price, they often resell "OEM" SKU's, which have no warranty at
all from the manufacturer (the idea is that if the unit breaks,
you have to get satisfaction from the OEM that you bought it from,
and the Canada Computer warranty is 90 days -- I've had that
happen to me there. <br>
><br>
> My normal distributors don't let me buy the OEM skus (I would
need special authorization, etc.), and I'm not sure how a street
level retailer would qualify as an "OEM" (given that they can't
claim to be manufacturing or integrating anything), so it was a
pretty nasty shock to find out that I had accidentally ended up
with a costly paperweight.<br>
><br>
> Now that I think of it, I should try and find the
receipt/details on that transaction, and complain to Seagate --
the more I think about it, the more it seems that a retail store
selling OEM SKU's like that is just plain *wrong*.<br>
