WD Red drives park their heads like WD Green drives?

I know it may be just a nonsense to justify why they're denying support, but I am told by support that 4TB RED are seen causing trouble on some units. I am also told they are being tested on OS6 machines now, and that for the time being there are no plans to test them on OS4 in the future.

I have those drives, and experienced ONE kernel crash on my unit. It may be relevant, it may be not, I just thought I should add it to the conversation.

I just confirm > I HAVE BOUGHT NEW WD RED 4TB today, i have checked default value by using guide from posts in this topic and IT IS SET BY DEFAULT TO 300.

After 80 days (24/7) my 2 WD RED 3TB WD30EFRX-68EUZN0 have these values on a ReadyNAS102:

i think these values are good in terms of a NAS environment

My oldest looks like this:

Raw Read Error Rate	0
Spin Up Time	5650
Start Stop Count	349
Reallocated Sector Count	0
Seek Error Rate	0
Power On Hours	15374
Spin Retry Count	0
Calibration Retry Count	0
Power Cycle Count	13
Power-Off Retract Count	7
Load Cycle Count	341
Temperature Celsius	31
Reallocated Event Count	0
Current Pending Sector	0
Offline Uncorrectable	0
UDMA CRC Error Count	0
Multi Zone Error Rate	0
	
ATA Error Count	0

I just installed 2 WD Red 3 TB drives. The number look better than others, but should I be happy about these readings.

The numbers look normal to me. It looks like you have disk spindown enabled. If so, what threshold are you using?

Is there something in particular you are concerned about?

I have the spin down set for 10 minutes.

I just have a basic concerned based on some of the comments in this thread and on the internet in general about the Red drives. Seems like a number of people have had premature failures of the drives.

That explains the high start/stop count. I don't see any problem leaving the threshold there. Personally I use longer thresholds (~60 minutes).

For a brief period a WDC firmware change reset the head parking threshold too low for the ReadyNAS - which resulted in rapidly rising load cycle counts. They have since fixed that (and provided a tool to allow people to adjust those thresholds themselves if needed).

If you had that issue, your load cycle counts would have been much higher.

I don't know about the "internet in general". I am running 8 of these drives in various NAS (a 2 TB model in a duo v1, 5 3 TB in a pro-6, and two 3 TB models in an RN102). The oldest has been running more than 15000 hours, several others are over 10000. The newest has about 2700. I've had no problems with any of them.

As far as I can tell from the posts here, NAS users are finding them to be quite reliable. Note that all drives have some failures, and people who have problems are more likely to post their experience than people who aren't having any.
