[dynek]

Orderable is a big word
They showed up on Steg PC: http://www.steg-electronics.ch/de/artic ... 0&y=0&cp=1

Key differences are primary warranty and the on-recoverable read errors per bits read.

4) Controlled unload at ambient condition.
5) Based on a typical NAS product environment under normal operating conditions.
6 The term of the limited warranty may vary by region. Visit http://support.wdc.com/warranty for details.
7) No non-recoverable errors during operating tests or after non-operating tests.
Longer warranty coverage The WD Red drive is backed by a 3-year limited warranty for greater peace of mind.

I might consider the new RED drives if WD offer a refund for the ** WD10EADS they sold me.

Why would they do that?

[occamsrazor]

I'm definitely interested in these for my TS-239 Pro II. But slightly off-topic... Can anyone tell me if, taking into account their supposed NAS/RAID friendly features, whether these would also be suitable for an external direct-attached hardware RAID-1 external FireWire drive?

[Clarke]

My co-worker and I bought the TS-669 Pro yesterday and bought 6 each of these RED drives today. We were going to go with a Hitachi but as soon as we saw this and the benchmarks today, we e-mailed our contact to get us these. So we have both products on the way.

We're planning on using a RAID5 when we set this up so we can try to answer some questions for you guys regarding these drives.

[P3R]

The key for the HDD prcing are (beyond size and capacity):
a) RPM
b) Warranty terms
c) MTBF

Add to that list the Non-recoverable Read Errors per Bits Read specified. With very, very few exceptions that is always 10 times less for desktop disks compared to enterprise models.

That particular value is also more and more critical the larger the disks become.

[P3R]

Let me remind everybody about one thing in this sudden euphoria over WDs return with a usable desktop disk: using a very recently introduced disk is always a gamble.

There have been several examples of disks that have been on the Qnap disk compatibility list and then later removed when problems have started (several so called WD IntelliPower disks come to mind in this regard ). At least this time WD will probably assist in resolving the problems but it will probably not happen instantly.

I do however find it very pleasing that the WD strategy of banning the use of desktop disks in NAS/RAID-application have apparently failed big time.

Us customers that have been persistant in not using any WD desktop disks have actually made an impact. This is consumer power in action!

[P3R]

Can anyone tell me if, taking into account their supposed NAS/RAID friendly features, whether these would also be suitable for an external direct-attached hardware RAID-1 external FireWire drive?

As far as I know there is no FireWire-interface on any Qnap so the question is off-topic in this forum.

Furthermore since the disk is hardly even introduced yet, it have definately not been available for any mere mortals to gain any experience with it.

You should ask the manufacturer(s) of the equipment you want to use it with if it is compatible.

[paolomarino]

In the Qnap compatibility list there is the WD30EFRX for the TS509 with no note.
So this 3TB disk is compatible with the TS509 ???
Thanks.

[P3R]

So this 3TB disk is compatible with the TS509 ???

No, since the TS-509 doesn't support anything above 2 TB that's a mistake.

The 3 TB model should, as all other 3 TB or larger disks in the disk compatibility list, have Notes 11 and 12 as a remark. I will make Qnap aware of this and hopefully it will soon be corrected.

If you are wondering what the difference between the green and red drives are then this article may help:

I took the plunge as my green drives were dying..

I suspect I may regret the early adopter status as the drives are "chirping" louder then any drive I've ever owned. It's not constant but the Raid 1 is still doing it's initial sync. Been a while since I've done that and with 2x2TB Red Drives, taking nearly 7 hours to Format/Sync before I've loaded any files.

When I'm not hearing the chirp, they are nice a quiet, over course the fan in my 439pro is causing more noise. Wonder if I can swap that with something more silent.

UPDATE - So the Chirping noise turns out not to be the Red Drives.... But my external backup drive that I was restoring from - that drive has been silent until now and given my distaste from the Green Drives and frustration trying to overcome the Raid issues, I jumped the gun with my conclusion.. Sorry for the confusion. Move along...

[redgoblin]

"chirping" louder then any drive I've ever owned.

As one of the above review's conclusions was "Whisper quiet operation, even while seeking!" (underlined here by "No rattles, ticks, or other sounds you'd hear from the other drives. The Red is clearly tuned for dead-silent NAS operation.") you may have grounds for complaint there - if you're sure it's a Red making the noise. Are you starting from scratch or do you still have some Greens in the mix to possibly confuse the issue on their way out?

PS: Thanks for the review link zxlife

spc337: Thanks for the update (EDITed above) about the chirping.

Looking forward to your conclusions when everything's sync'd in and running normally.

I intend to buy the TS-1079 Pro together with 10 Seagate HDDs. (ST32000641AS)
But since the price for this HDD sky-high I always delayed the purchase. Now I saw the WD Red Drives at a good price and considered to buy this HDD instead. But on the WD website I read 'Specifically designed and tested for small office and home office, 1-5 bay NAS systems.'

Now I'm somewhat clueless. Should I buy the ST32000641AS or the WD20EFRX? Or has someone a better idea?
