HDs
« on: December 05, 2012, 06:04:11 AM »

Hi all

just ordered the Station, now I'm searching for 2 2TB HDs...

what about HDs rpm ?

I'm studiyng the WD20EARX but it is a 5400rpm .....
Do you think a 7200rpm is better for Media Service and, in the meantime, robust enough ?

over the internet I found both pros and cons... but more pros...

Experiences?
 
thx

The price difference between 5400 and 7200RPM's is negligible. If you were to put in 5400's vs 7200 the transfer speed would be identical. I would just go with what's on sale.

I can say something about commonly used Western Digital drives: WD has several flavors of its hard drives:

  • Blue - mass-market - intended for mass market desktops/worstations (e.g. WD10EALX,WD10EAEX)
  • Green - economic - intended for desktops/worstations with lower consumption (e.g. WD10EARX, WD10EZRX)
  • Red - durability - dedicated for NAS devices (e.g. WD10EFRX)
  • Black - heavy-duty - intended for servers (e.g. WD1002FAEX)

So if you intend to run your NAS 24/7 you should invest money in red drives (3 years warranty). They are silent, and have low consumption like green ones. If you don't need 24/7 then green ones (2 years warranty) fit well too. I bought 2x2TB green ones (WD20EARX) and they work fine. EARX are little bit slower (110MB/s) than EZRX (126MB/s) drives but work more silently and with lower consumption. However, I think that nobody should bother himself too much about speed (you will not reach this speed anyway in your NAS, no way), and differences between consumptions are really nothing, etc. Silent work, warranty, capacity (of course) and finally price - do matter.

If you want to compare and choose, maybe this helps: WD hard drives matrix comparison

I've added this information to the HDD Compatibility list sticky thread.
