Poor access time according to HD Tune on WD5000AAKS

Recommended Posts

Just got the drive and all seems to be working very well, but ran HD Tune and my access time is 19.0ms. Seems awfully slow. Any ideas what is causing this? Is the drive really likely that slow?

BTW, I've tested the drive both using HD Tune from the drive and using another drive with the same result (Maxtor 100gb SATA---HD Tune -->WD5000AAKS and then WD5000AAKS --HD Tune-->WD5000AAKS). So I'm thinking we can rule out something accessing the disk and screwing everything up, right?

Not that anyone looks like they're going to jump in, here is the actual test:

I just received my WD7500AAKS (16Mb cache) and so FWIW I ran HD Tune on it for comparison. My Access time is an appropriate 13.4 on a bare drive and using it as a second drive with no activity:

HD Tune 2.54:

I was wondering if there was something wrong with the 2.53 version you were using so I found an old copy and tried it as well and it is virtually identical results as the 2.54 version:

At this point I can't say what is your problem but I agree your access time is horribly high compared to what it should be.

Check if your drive is set into AAM enabled mode...

Yes, I tested that yesterday. I was set to AAM. I turned it off and retested and got the exact same result. This morning I tested with HD Tach, also got close to the same result (a tad bit worse). So its been tested with new cables, on a different SATA port, in a different computer, with AAM on and off, and I get the same result every time. And after three days, I'm still waiting to hear from WD on this.

I just bought 6 WD5000AAKS drives for work. I've tested two of them and they both have very slow access times of 19ms reported by the most recent versions of HDTach and HDTune. I've disabled AAM on both with no access time change at all. Tried it on 3 different platforms - 2 PCs and one server. My HDTune graphs are virtually identical to yours. Not too pleased with this at the moment. Going to give WD a call as well.

Anyone considering one of these drives, consider this:

1 - some hardware manufacturers are known to cheap down a product after most of the hardware sites have reviewed them.

2 - I send three emails regarding this to WD over the past week, none have been replied to

3 - Others here have spoken with WD techs and been told basically "too bad".

4 - Every day I find another person who's reporting 19ms access times, not 14ms, 15ms, 16ms, 17ms, or 18ms, just 19ms or the expected 13ms. This shows to me that there is something changed between those that are getting 13ms and those getting 19ms. Have they change a component to save a buck?

I'd say that 80% of the drives I buy are WD, not any more. Not only that, they now only provide 30 days of tech support. Since I also got one of those Seagates with the faulty AAK firmware, I guess I'm stuck with Hitachi, Samsung or Fujitsu.

> 19ms access times, not 14ms, 15ms, 16ms, 17ms, or 18ms, just 19ms or the expected 13ms.

Some of these guys are comparing the 7500aaks to the 5000aaks which is wrong because they perform differently. Are you sure there are other 5000aaks users who perform the same benchmark as you and get 13ms instead of 19ms?

Besides that, hardware, drivers, and OS can affect this stuff too. It wouldn't be unusual to see some people getting different results from changes in these variables!

Absolutely. I've seen the screen shots.

I would agree, but I've tested my drive in two different systems with identical results. If you check the post from Rick, you'll see it supports what I'm saying. I have four others who've recently bought the drive who are also reporting the same thing.

In that case good luck, I like the WD drives of this generation, but WD email support sucks candy canes :(

Are you sure you have a current AAM utility from WD? Are there different revisions?

As far as I'm aware, WD doesn't have a AAM utility. You need to use the Hitachi one.

Has anyone been able to resolve this issue? I have 13 other WD5000AAKS drives (6x 00TMA0, 5x 22YGA0, 2x 00YGA0) that all test around 13ms, but the one 65YGA0 I have tests at 19.1ms. I, too, tried turning off AAM using the Hitachi Feature Tool to no avail. I suppose I can dedicate this drive as a hotspare, but I'd rather get this resolved.

I saw on another forum that someone changed AAM to fix this. It appeared to me that the problem was that not every tool can change AAM on every drive that is attached to every SATA controller.

I'm surprised WD support is so crappy that nobody has been helped by them yet.

Interesting. I had tried using the HGST Feature Tool to disable AAM completely. It appears as disabled, but doesn't make any impact on access time performance. However, after finding a thread at NCIX, I tried enabling AAM with a value of 254 (as far to performance side as is possible). That worked--HD Tune now tests at 13.1ms. Odd that only the 65YGA0's have AAM enabled by default.

It would appear that the HGST tool isn't completely capable of disabling AAM on at least this WD drive. It's too bad WD doesn't have an official tool.

I'm on my second Samsung F1 1TB and like the previous it has an access time of about 22ms in HD Tune and HD Tach. What do you think I should do?

My HD103UJ has 14.1ms by HDTune 2.53.

I think you should check out AAM issue, HUTIL is Samsung official utility.

Hello to the forum,

I recently got 3 WD5000AAKS. One 00YGA0 and two 65GA0. Because of this thread I immediatly started HD tune 2.54 and discovered that that the 00YGA0 showed an access time of 13.4 ms and the two 65GA0 had an access time of 19.3 ms! I searched for a tools to adjust acoustic management and found this little tool.

http://www.withopf.com/tools/aam/

As I'm located in Switzerland the tool itself is in German but it is very easy to use and it works under Windows.

The tool said, the acoustic management on the two 65GA0 were set to quiet (128). I used WINAAM to set ist to loud (254) and now I have three WD5000AAKS with an access time of 13.4 ms. :)

I know this is older but I was in the same boat with my 7k1000 Hitachi. 18.9ms access. Turned off acoustic management and it dropped to a nice 13.9ms.

69.3 MB/s average / 151.4 MB/s burst.

I see that it is an old topic, but I have green WD WD5000AAKS-00V1A0 which works very slow :

If I try new firmware is it possible to make it work normally? And where can I find firmware for this model, because for now can't find any?
