Well, don't fix what is not broken. Now network space running out due to the 60D. topping it the network storage. Ha!

Canon huh..

Canon huh..

Yeap. a Canon camera! Took some pictures of the Synology DS412+ with it.

Hi.. thanxs for the headsup.. i'll go check this out later tonite when i'm home.. hopefully the DSM i'm using already got this fixed..

Samsung F4 2TB? This drive had big problems with an earlier DSM release on the 1512+. The symptom is that the drive will click every ~21sec, and eventually develop bad sectors and need replacement.

It's fixed on the later DSMs for 1512+, but I don't know if the 412+ is affected in the first place, nor if the fix also affects the 412+.

More details here if u interested: Synology Inc. Online Community Forum - NEW NAS Experience -View topic - DS1512+: HD204UI Load_Cycle_Count increasing every 21sec

Hi everyone, just an update on this.

seems that the new firmware at 2228 has fixed the prob or it doesnt exist on the DS412. I dont notice any clicking sounds when the hdds are idling or working. Checking the Hdparm for the APB_level also returns me 254 which is supposed to be the parameter that solved the click click clicks..

Updated with the software installation, add-ons and most importantly the speed tests...!!

Good review TS makes me gian want to upgrade my nas.

Thanks for the review, very informative indeed.

Noticed that your 1st Synology is the 1511+ instead of the current 1512+.
Guess the 1512+ performance may be on par with the 412+?

Given the better specs of the DS1512+ it should perform better than the DS412+. Also DS1512+ is extensible up to another 10 bays whereas the DS412+ is not. Hence it all boils down to your requirements n see which one fits u better..

Synology DS412+ Speed Test

Have done a similar speed test like TS with NAS Performance Tester. The DS412+ is populated with WD Red WD30EFRX 3 TB drives.

Results as follows:



Managed to achieve 110.71 MB/s (write) and 113.55 MB/s (read) when using a 2000MB file. It is excellent considering that the max theoretical speed of 1 Gigabit LAN is 125 MB/s.

The equipments used, set up and limitations can found in DS412+ Speed Test.

Just tried running the same test with Jumbo Frame enabled at various values of MTU. Managed to push the xfer speed of Write and Read to about 105MB/sec but it doesnt seem to be stable and consistant compared with Jumbo Frame disabled.. Sometimes the rates will drop to 70 MB/sec during the 5 runs. Without Jumbo Frame, I can maintain consistent results even between each test..

Some devices are accessing your network hence the drop in speed?

No leh.. I took out everything from the Router except my PC and the DS412+ to run another round also the same. Once i disable the Jumbo Frame, my RW speed goes back to > 90 MB/sec.. weird..

Thanks!

In my previous 411+ (not affected by this issue) the APM level was 255 (ie. disabled), but in my 1512+ it's 254. Hence it seems the value was also overwritten on your 412+, which is not surprising considering the internal h/w of the 1512+ and 412+ are so similar. So with firmware 2228, this issue should be fixed on the 412+ from Synology's point of view.

If you're free, could you help me to do the following test to see whether the fix kicks in during system bootup, or after the OS has loaded?

1. Note down the Load_Cycle_Count "Raw data" value
2. Power off the NAS.
3. Power on the NAS
4. Note down the new Load_Cycle_Count "Raw data" value

If the fix is done during bootup, the value should only increase by 1. If not, it means your F4 drive will be ticking for 1-2mins while the OS loads... I couldn't test this becoz my F4 2TB was dead/gone by the time the fixed firmware came out.

Hi Chong,

I just did what u wanted. The count only go up by 1 after the Power On. I'll leave the DS412+ to run over nite n see if the count will go up or not.. Hope this helps u.

Anyway, if based on this, Synology is not really solving the problem but just preventing the F4 from going to sleep.. Also, in any case, if I do keep powering on and off the NAS, say on a daily basis, it's a matter of time the Load_Cycle_Count will hit a freaking big value too..

Since the count only went up by 1, then the issue was fully resolved! Thanks a lot for testing it out!

Anyway, if based on this, Synology is not really solving the problem but just preventing the F4 from going to sleep..

From my understanding, the issue was a combination of:

1. Some F4 firmware will park the heads after ~21sec of no activity when APM level is below a certain value (224 happens to be within this range)
2. Synology's DS1512+, 1812+ (and I think 412+) with DSM version 4.0-2198 and older will set the APM value to 224 during every power on
3. The F4 drives will fail when the heads are parked every 21s, and will develop bad sectors in a few days.

By right, no APM value that the drive accepts should cause it to self destruct, so IMO the fault ultimately lies with Samsung's F4 design.

Also, in any case, if I do keep powering on and off the NAS, say on a daily basis, it's a matter of time the Load_Cycle_Count will hit a freaking big value too..

Not really... with the ~21sec bug, the Load_Cycle_Count will increase by ~4100 per day. You'll need 5.6 years to inflict the same amount of damage from power cycling, assuming you do it twice everyday

Sorry to derail your thread, and thanks for sharing!

Hi Chong, no worries. Glad that I'm able to help. After leaving the DS412+ running for almost a day, the Load-Cycle_Count still stays the same for the drive. So it really seems that so long you dont restart the NAS, this value will be constant.

bros im looking for get a 412+ as well. anyone know where is the bset lobang?

 

[kd2000]

Thanks for the great review! I am planning to upgrade my DNS-323 and was thinking of getting Synology NAS. I find the price for DS412+ is very expensive (around $1100).

My 412+ have beep sounds,any idea?

i think there are alot of them whom have already replied to your question but you failed to reply them.

One of your hard disk is likely crashed. Login and check each hard disk status.
