WDC WD15EARS-00Z5B1 awful performance

I have the HDD since last friday. From time to time it's performing pretty bad.

 

http://community.wdc.com/t5/forums/forumtopicpage/board-id/caviar/thread-id/37/page/2 - I think  jayoungf9 has very similar issue.

 

What I've noticed: (the tests have been performed on win XP SP3, both on onboard and PCI SATA controller). Also tried via USB docking station and another PC with XP SP 2. FAT32 and NTFS tested. I also tried with jumpers on pins 7&8 (for use as a single drive) and the WD utility. It said that drive is performing optimal...

 

- with one single partition, as soon as I fill 70% or more, it starts to write with speeds betweeen 900kb/s and 2 MB/s, most of the time with around 1MB/s.

- Then I read some forums and got the idea to try with more that one partition (one small -20GB and two big, almost 680 GB each).  The behaviour occured only with the partition that was in the first half of the drive. I thought that it could be due to bad sectors or just faulty plate, but it happens only with the last 10% of the HDD capacity... Which is really strange.

- Then I tested with adjusting the sectors to 512 and 1024, nothing changed.

- Also, if I start encrypting the drive, it does it with about 5-6 MB/s. For example, the older WD 1.5T green drive does it on my system with about 30-40 MB/s.

 

 

I found no firmware for this model... Can someone help? It might be either a bad revision, or a FW bug...

Re: WDC WD15EARS-00Z5B1 awful performance

I am having the exact same problem with the WD15EADS.  Last night I started to transfer 136GB(38,250 files) from one internal WD Raptor drive to this new WD15EADS.  The WD15EADS is getting response times of 5,900 ms to 21,000 ms.  While I was sitting here I did see a moment in time where all the response times went up to less than a millisecond for all files in the IO queue.  I am monitoring the IO queue with Windows 7 Resource Monitor.  I wonder if this has something to do with the 32MB buffer the hard drive manages.  I might try to investigate into the WDIdle3.exe tool I've been hearing about.  If you find a resolution please let me know.

Re: WDC WD15EARS-00Z5B1 awful performance

I wanted to further comment that I had a brand new drive and only created a 596MB partition on it in which I am using.  I haven't experimented changing partitions/sizes.

Re: WDC WD15EARS-00Z5B1 awful performance

I'm happy to share with you that the aligh utility managed to do a conversion. This happened after I deleted the partitions and created new. So far the performance is significantly better! The encryption works fine, copying speed is 50% faster. Actually I am not able to define the maximum throughput due to limitations on my system.

 

I will inform you in about 15-10 hours if the "slow-copying" issue has occured at the end of the drive.

 

So - for now the align utility seems to be helpful. Strange why it didnt find a need to convert at the beginning.

Unfortunatelly the slow-copy issue occurs again... and again at ~85-90% full capacity

[ Edited ]

Same problem here - with 2 WD15EARS-00Z5B1 - under linux (2.6.31) and ext4 fs - system is irresponsible and I can't do two task or more at once (for example copy something and using finch / rtorrent). There are huge latencies while using terminal :smileysad: I hope WD will fix this by firmware or I'll have buy two Samsung F2EG and sell this creepy WD :/

Re: WDC WD15EARS-00Z5B1 awful performance

for problems with linux and WDxxEARS drives, there is a seperate thread about it:

Re: WDC WD15EARS-00Z5B1 awful performance

Maybe linux is not the issue...

 

I got a replacement drive by my vendor. Situation seems to be the same so far: 200 GB free left and again writing goes down @ 1 mb

 

I still have NO reply by WDC support on my case. I opened the case on 11th Jan and  according to WD, the response time has to be around 1-2 days...

 

The next time I buy HDDs maybe the lack of support will take part in my decision.

 

The drive isn't even listed under the Caviar Green download section!

Re: WDC WD15EARS-00Z5B1 awful performance

I have 4 of these drives and I have had nothing but problems with them in a NAS, raid5 volume read/write performance was appauling, volume crashed. 

The above is software (Linux) raid so it is theoretically fine to use non raid/enterprise drives as they don't get booted out of the volume as quick as hardware raid does if the drive fails to respond.

 

Split up the drives, reformatted, and now in Windows7 trying to get data on to one of them is up-down-up-down-freeze-up-down...... averaging 16MB/s, random freezing, occasional speed increase to 25MB/s..... transfer started out fine at 60MB/s.

 

Source files are on a 200GB SATA HDD via onboard SATA1
Destination drive is on same controller @ SATA3

 

I get a steady 45MB/S copy speed with other drives on SATA0 and SATA4 of same controller with SATA1 source and between any other combination apart from the WD drive, so its not my 200GB drive or the controller.

 

I asked WD for a test tool and they told me they dont have one for Windows 7.  Well thank **bleep** that 7 ships with VM-XP then eh WD?

 

I also tried copying files off of external 500GB WD drive via usb and found it also takes forever, slowing down to under 1MB/s.......when traget is the 1.5TB WD drive.

 

Once I have a full copy of this data on the WD drive I will test the other 3 WD drives on my PC to see if it is common across all or not.

Re: WDC WD15EARS-00Z5B1 awful performance

I have a hdd wdc wd15ears-00z5b1

I installed Windows XP on it and got very slow system working speed.

The 300 Gb of data is being copyed about 24 hours!

I tried to install Ubuntu, got the same.

It was ready at morning, so the installation process of ubuntu longs about 8 hours!

 

After that I found some topics in the internet about it and try to do this:

1. I downloaded program wdidle3.exe and try to increase idle time. I run program like this: wdidle3 /d

Nothing happens better.

2. I downloaded program wdalign from wester digital web site and run it.

I did it yesterday, the program till does not end!

 

Recomendations:

If you have a new hdd wdc wd15ears and ability to copy data from old hdd to new one, it's better to set jumpers to enable advanced format and set up new system.

 

Using of utility wdalign takes a lot of time!

In my case with 1,5Tb hdd it takes more than 30 hours!
