Power disable feature on readynas 422

Question

Does ReadyNAS 422 support HGST Ultrastar He10 HUH721010ALE604 (0F27454) with Power Disable feature?

StephenB · Answer

The&nbsp;WD Gold WD101KRYZ should be similar (since WD owns HGST), and of course there is also the&nbsp;IronWolf ST10000VN0004 or the IronWolf Pro ST10000NE0004.
&nbsp;
Note that if the drives don't have a center mounting point on the side you might need to remove the plastic inserts in the disk trays, and then attach the drives via the mount points on the tray bottom.&nbsp; The NAS will come with a package of screws that are used for this.&nbsp; The details on removing the insert are in the hardware manual (toward the end).&nbsp; That part of the manual is focussed on using SSDs (which also requires removing the inserts).
&nbsp;
Netgear is apparently changing the inserts to be compatible with drives w/o the center mounting point, but your NAS might not come with the new ones.

Hi ggmasluka

&nbsp;

Welcome to the Community!

&nbsp;

This feature became a standard on SATA III rev 3.3, This type of drives are not tested yet for compatibility with the ReadyNAS systems and even HGST does not recommend it on untested Chassis.

&nbsp;

This is due to the drive's possibility to not spin up when 3.3v power is being provided in Pin3. It is recommended to use HDDs without this feature for now to avoid any issues.

&nbsp;

Here is a link to an article for HGST Power Disable feature&nbsp;and another post that may add up to this reply.

&nbsp;

Hope this helps!

&nbsp;

&nbsp;I see, IMO I would go with the non-PD drives, other brands are available&nbsp;but of course it is still your call.

&nbsp;

As the manufacturer stated if you don't specifically need the feature it would be better to stick with the non-PD version.

&nbsp;

Hope this helps!

Hi ggmasluka

&nbsp;

That is good to hear though it's noted that the compatibility of the drive was based using the test from the same series which in this case might be a non-PD HDD. But still if you prefer to use it, As stated&nbsp;it may or may not spin up on the chassis.

&nbsp;

If you already have the drive it would be great if you can confirm the compatibility of the drive on your RN422.

&nbsp;
