WD Green Drives no good for QNAP's??

[Ben Martin]

I also have a Qnap TS 509 Pro II with 5 WD Caviar Green 1.5TB on 3.2.5 firmware. But for some reason it has been acting strange for the last 3 weeks.
. . .
My question: is there a way I could improve writing and copying from my NAS without changing my drives? Is there way I could get my NAS to work properly with WD Caviar Green 1.5TB in RAID5 or is there a good fix soon out there?

speaking from direct, lengthy and very painful experience i would say absolutely not. there is no way to improve writing and copying from your 509 Pro without changing your drives.

i have had a 509 Pro with 3 x WD15EADS and it has had exactly the same problem ever since i bought it almost nine months ago. several months were burned going back and forth via e-mail with QNAP tech support, sending them log files and such, installing betas of new firmwares supposed to address exactly this issue. in the end they even swapped out the unit, sending me a brand new 509 as a replacement... but of course it had the same problem as it is caused by the drives.

in the meantime, i have tried everything i could think of to check/fix the drives but have basically been wasting my time (a LOT of it). then today i discover "Note 8" at http://www.qnap.com/pro_compatibility.asp, which explicitly states:
There is known performance issue with WD15EADS-00P8B0 and WD10EADS-00P8B0. These two HDDs are not suggested to use with QNAP NAS.
these are the exact model and part/batch(?) numbers of my drives, and QNAP knew this before they sent a replacement 509! WTF?!

anyway, the point is that this whole HDD compatibility issue is a lottery at best, so not only do you need to buy new drives but there's still no guarantee. and based upon repeated experience i'd have to say that once they have your money for the NAS box itself QNAP simply don't care, as the drives are "at fault" and they don't make them.

We have a TS809U-RP with eight WD20EADS. The drives were chosen because they were not mentioned in the note. I wonder if they are going to have the same problem(s).

[Tarrant1701]

So, my question is: does those Seagate have some sort of issue with the lack of a TLER (or whatever it is called under the Seagate brand) just as the WD desktop drives?

Looks like Seagate has the same issue with their "desktop drives" which they consider to be a "less demanding environment" so it lacks ERC aka TLER as well:

here are my current values for my WD15EADS
Power_On_Hours = 3032
Load_Cycle_Count = 8
Start_Stop_Count = 9

is my drive affected or not (and how long (estimated) does it take for 300000 LCC is reached on my drive as the formula for this has beaten me)

Wow!

I know I said I was out of this thread ( ) but I had to state 'wow' for a second because this must be one of the lowest load cycle counts I have ever seen lol

Here's the formula with your numbers (formula is based on running the disk 24/7/365):

LCC = 8
POH = 3032
MTBF = 300,000

3032 / 8 = 379 (means: only 1 load cycle per every 379 hours!!)
300,000 * 379 = 113,700,000 (hours until 300000 LCC is reached)
113,700,000 / 24 = 4,737,500 (days until 300000 LCC is reached)
4,737,500 / 365 = 12,979.452 (years until 300000 LCC is reached)

LOL! this drive could theoretically last quite a few life times! So, no, you are most definitely not having an LCC/SSC issue there

If I may ask, is this drive running in a QNAP NAS?

Kind regards
John

yes this drive is running inside my qnap ts259

here are the latest value's:
Power_On_Hours = 12340
Load_Cycle_Count = 13
Start_Stop_Count = 14

that would mean this sum:
12340 / 13 = 949 (means: only 1 load cycle per every 949 hours!!)
300,000 * 949 = 284,700,000 (hours until 300000 LCC is reached!!)
284,700,000 / 24 = 11,862,500 (days until 300000 LCC is reached!!)
11,862,500 / 365 = 32,500 (years until 300000 LCC is reached!!)
32 thousand years before 300000 LCC is reached??
this can't be right, can it?

[eagle00789]

here are my current value's again:

Power_On_Hours = 12985
Load_Cycle_Count = 14
Start_Stop_Count = 15

that would mean this sum:
12985 / 14 = 927.5 (means: only 1 load cycle per every 949 hours!!)
300,000 * 927.5 = 278,250,000 (hours until 300000 LCC is reached!!)
278,250,000 / 24 = 11,593,750 (days until 300000 LCC is reached!!)
11,593,750 / 365 = 31,763 (years until 300000 LCC is reached!!)
31.7 thousand years before 300000 LCC is reached??
i still can't believe this is correct.....

can anybody verify if my calculation is correct??

Hi
I have bought QNAP TS-219P+
which hd can I buy the best for it?
Initially I wanted the western digital caviar green 2 TB,64MB, 7200 rpm but they aren't good
So which?
better 64MB and 7200 rpm as the wd?
or the samsung ecogreen 32MB 5400 rpm?
thanks

If you use the Enterprise Raid edition drives they are fine, so go for WD 2TB RE4 (7200) or the ones I use which are WD 2TB RE4-GP (lower speed more energy efficient cooler green edition). The NAS or network will be the bootleneck, not the drives whichever you choose.

and something cheaper?

and something cheaper?

Previously used the Samsung F series drives (F1-F3) with no problem in a Ts-119.

[qunappo]

yes but I want use them in a RAID1
will them works?
now there is the f4 series

[petur]

Samsung disks work fine in RAID, I have been using them in RAID0, RAID1 and RAID5, as external disks and inside NMP-1000(P). No problem.

I think the F4 also do 4k sectors but I'm pretty sure QNAP firmware supports that fine.

[adihartono]

I want to put (install) SATA II Green 500Gb 32 MB WDC into the QNAP TS-210 Turbo Nas.

Is it compatible to the Qnap Drive ? Is it recommended ? Please, need your advice

Thanks in advance.

Do not buy WD green drives! They have a short life in a raid configuration, better to spend a bit more money than have the trouble that I am now in. I have/had 4 WD15EARS in my system that has been running two years now. I now moved to WD2003FYYS 2 tb RAID drives.

One disk crashed and was not accessable and while rebuilding this disk another one came up with read errors... I do have very good backups but the hassle of completely setting up databases shares users/ MSV2, etc, etc. will give you a major headache.

The famous lifecycle count for the disks was around 100k for one and 50 k for the others I could access.

Just don't take the risk...

Another lesson learnt for me is to enable the automatic health checks (was lazy, never done it...) this might have warned me before the two disk failure. I am now also moving to raid 6 that's why I bought a bit more bugger drives. This way at least I can have two drives failing on me...

[MrSimmo]

Agreed, I've got 4x WD20EARS's in my 419p+ not raided. One's failed completely and the other 3 have load cycle counts of between 200,000 and 400,000 in a year and a bit of use! WD are swapping out the failed one but I would definitely stick away from these on unix system (QNAP etc). The WD Blacks are supposed to be ok, never used them myself though.

Only found out about this issue a couple of months ago. You can download an app that you can compile on the QNAP to run natively and disable the "Intelligent Green" feature of the drives, saves you having to pull the drives and stick them in a Windows box. http://idle3-tools.sourceforge.net/ . It took me ages to get the optware development stuff and compile, had all sorts of issues like QNAP kept trying to use CC instead of GCC to compile so if you've got a 419p+ or similar, I've attached my pre-compiled version for you... It'll void your warranty I suspect but its easier for people like me who don't want to have to keep swapping out the drives once they failed and restoring from backup...

Theres a good page of info here: http://forums.whirlpool.net.au/archive/1367904

check my siganture for the drives that i am using.
