WD40EFRX WD Red 4tb For ReadyNAS104?

We are testing in this weekly.
Factory default with 4 pcs WD40EFRX on RN104, it seems OK, I need to do more testing.

Any idea when you'll know / when they'll be added to compatibility list ?

On the verge of buying a RN104 - and I've come to trust WD drives so would prefer them over the Seagates. (But don't want the expense of the Blacks/Enterprise disks)

Evan, I reported a problem with the WD40EFRX drives in my Pro Pioneer and Ultra 2 Plus:

https://www.readynas.com/forum/viewtopic.php?f=24&t=73417: The drive's Idle3 timer is set to 0x50 (8 seconds), so the Load Cycle Count (SMART attribute 193) increases very rapidly: It will reach its rated limit in just a few months.

Have you seen that problem with the RN104?

Hi Guys, i know the new 4tb red WD40EFRX is pretty "new" to the market. Has anyone tried one of these on the netgear readynas 104? i'm thinking to get one these..

I've been running them in a 314 for three weeks now with no issues. I figured since all three of the smaller ones, a black 4TB desktop and the 4TB RE were listed, it would eventually make the list. We'll see what happens over the long haul.

Have you checked the load cycle count?

, load count is 83402 on drive 1, 76748 on drive 2, 82595 on drive 3, power on hours 553.

Load Cycle Count; Load/Unload Cycle Count S.M.A.R.T. parameter indicates the number of cycles into Landing Zone position. \\

Comes out to about three times a minute. That's ridiculous. Trouble is, some operating systems regularly write something onto the hdd causing a few load/unload cycles a minute (typical Linux example: /var/log/*) :(

I just ran S.M.A.R.T. across an old WD Blue 320gb hard drive that I am using for a swap drive in a Windows 7 box. Power on hours 25302, Load Cycle Count 15629. Seems that OS6 Linux based OS could stand a tweak or two not to write so much to the hard drive or Netgear could support the drive and tweak the power management setting for the drive if they decide to support it. Unless someone out there now knows how to do that on OS6?

In the mean time for the original post, do not buy them...and thanks StephanB for pointing me in the direction of saving my hard drives. I am shutting the 314 down until either I swap out for ECL hard drives or Netgear decides to support them. Or I can figure out how to change the power management options for the drives

One option would be to use idle3-tools: http://www.readynas.com/forum/viewtopic.php?t=59700

The steps might be a bit different for OS6 to the old OS, but you could give it a try.

The load cycle count problem is on Western Digital, not Netgear. Hopefully if enough people complain WDC will post a firmware update.

... Or change their policy to allow us to modify the idle3 timer value without voiding the warranty.

Yes.

But a NAS drive clearly should be configured properly for linux. The other RED drives don't have this issue - WDC dropped the ball here.
