WD20EFRX - WD Red with DUO v1

I see some interest in this drive working on the DUO v1 and thought my recent experience could be useful. Other threads reference this topic but are slightly off from the original titles so I hope starting a new post is proper etiquette. If you are a DUO v1 user, are interested in this drive and don't need to purchase urgently it could be worthwhile waiting for the Netgear guys to finish their testing of the WD20EFRX to see if it gets on the HCL.

After a disk failure it was time for a replacement and upgrade to 2TB. I have two backups (one offsite), the mirrored disk and all data can be replicated from other sources so I was not worried at all about my data which is for home use only. A local warehouse stocked the WD Caviar Green WD20EARX, it was on the HCL so off I went. The sales guy warned me about issues with Green drives on a NAS and sold me the new WD20EFRX confirming the WD site shows the ReadyNAS DUO as compatible (no version mentioned). Please no scoffing, but at the time I didn't even know there was a v1 and v2 and didn't even spot this on the HCL (going blind), perhaps WD should amend their site for us numpties.

To sumarise the last 4 days:
--> A couple of weeks ago I had upgraded to RAIDiator 4.1.9 via frontview (it showed there was a new version)
---> Removed the bad disk, backed up all data from the good one (I already had another which is the same but...)
--> Shutdown, inserted the first disk and performed a factory reset. First power up hung, found on forum powering off and on would fix it
--> Format and resync went fine.
--> Added second disk, format and resync went fine.
--> Connected USB backup drive. DUO hung had to power off physically.
--> Resync ran but when complete ran again automatically, restarted with volume scan all ok.
--> Restored approx 360gb data
--> Not happy with previous resync. Ran manually. It went twice again but left it. Finished OK.

Not sure if the double resyncs are normal but apart from that I am impressed. The disks are very quiet, I can't hear them...unlike the old Samsungs. The fan used to run at 2700rpm and now runs at around 1700rpm, it is the stock fan and has made it much more quiet. Access to the data is great from both windows and Mountain Lion.

I did not post this to recomend rushing out to get this disk for a DUO v1 immediately and as mdgm states please use the HCL. But it might encourage you to wait for Netgear as it does look hopeful. I am still a bit uncomfortable with my unsupported disk situation but am not in the warranty period anyway...the double resyncs maybe a concern too. If there are problems perhaps my wife will authorise a "v2" upgrade so not the end of the world, unless I physically trash them.

I have listed the SMART stats from disk one, disk two is similar but 2 degrees cooler. Sorry for the naff formatting. My old Samsungs had numbers all over the place, this to the untrained eye looks pretty good (no LCC's). I searched on the lpstats parameter and it seems to be no issue, indeed when I did a volume scan it seemed to reset this parameter.

Re: WD20EFRX - WD Red with DUO v1

Hi All,

I am in exactly the same situation. I have a DUO (V1) that wore out an old Seagate Pipeline drive. In looking for new disks, I found the new WD Reds and really want to buy a pair of the 2TB but am reluctant since that drive is NOT on the Readynas HCL.

I am very encouraged by reading this post. But the pair of Reds is nearly $300 so I don't want to make a bad decision.

Can anybody comment on the double resyncs reported by the OP?

Has anybody else tried the Reds in the DUO?

Many thanks for comments & feedback.

John.

Re: WD20EFRX - WD Red with DUO v1

The WD10EFRX is on the list for the NV+ (v1). Why it is not on the list for the Duo I cannot fathom since they have the same hardware. Why the WD20EFRX is not either list I cannot fathom unless they are tied up with other drives right now.
Remember - the NAS is not a backup plan.

Papa,

Thank you very much for your reply. But, I do not see the WD Red on the official HCL for the NV+. What am I missing.

Has anybody else tried these new Red drives in a DUO (V1)?

Thank you, John.

Re: WD20EFRX - WD Red with DUO v1

They are not on the HCL yet, apparently they are being tested.

whytega is running them on his duo (per the signature line above), and there are some folks running the 2 TB version on NV+ (though only the 1TB model is listed)

Though you risk losing support, in my view these are still the best WD drive option for 2 TB. The WD2002FAEX is the only other one I'd consider, and it is quite a bit more expensive.

Re: WD20EFRX - WD Red with DUO v1

On the NV+ listing, look at the 1TB drives, and the top most 1TB drive is a WD RE4 and the one below that is the WD RED WD10EFRX.

Yes. But he is looking for 2 TB drives for a duo v1.

Re: WD20EFRX - WD Red with DUO v1

Ah yes, PapaBear, now I see the 1 TB Red on the NV+ HCL. I'm so sorry I looked past it the first time. If it on the NV+ HCL, why in the world is it not on the DUO list as they are both SPARC and Radiator 4.1.9?

I really am looking for 2 TB drives for my DUO. Seeing the 1TB Red on the NX+ HCL is a very good indicator that the 2 TB Red will work on the DUO.

I don't really care about loosing access to Netgear for support as I know my DUO works with the original Seagate drive; and we have such awesome support here. Smiley Happy

Looking at the HCL for the DUO, I see the Seagate Barracuda LP model ST2000DL003. It is a 2 TB drive. This model seems plentiful on ebay and even new from Newegg for $119. Is there any reason not to go with this drive to get certain compatibility of a 2 TB drive on my DUO for about $100?

As always, many thanks. John.

Re: WD20EFRX - WD Red with DUO v1

Just in case it's of interest. One month later and all seems to be fine. Now have all 1.4TB of files loaded and the NAS gets fairly regular usage from me and the kids streaming movies, music, looking at photos etc. Stats are identical to my first post with the exception of power on hours (891hrs). Oh and temperature is down to 32 degrees.

Still hoping for it to get on the HCL but must admit compared to the old Samsungs which had ECC and LCC counts always changing this drive seems much better. Well to the untrained eye at least.

Re: WD20EFRX - WD Red with DUO v1

Thanks, I'm ordering 2 for my Duo v1. I'm optimistic that they'll work thanks to this forum.

edit: successfully updated/expanded to 2TB without issues. Added the drives while powered-down and didn't have to force resync or anything -just worked!
