Western Digital 1TB WD1003FZEX poor access time - Page 2

post #11 of 41
Hi. I am also seeing these much higher than typical (for WD Black drives) Access Times on my 1003FZEX. However, I do not know whether or not this is actually a problem. From what I can tell so far, the sequential as well as the random read/write results I'm seeing on CrystalDiskMark are quite good regardless of the Access Time being upwards of 16ms.

If I understand correctly, the Access Time is largely going to affect high numbers of small random reads and writes. But according to CrystalDiskMark, for HDDs the random read and write speeds of my WD1003FZEX are fairly good and at least on par with what the 12ms drives (like the WD4003FZEX) are providing.

Perhaps regardless of the higher Access Times the throughput for random read/write is just as good as the lower Access Time drives because the 1003 has a higher density single 1TB platter? And the bits are thus being read faster once the head gets to where it needs to read them? I'm guessing.

Here are my HD Tune results:



Also note the strange outlier access time points around 2% and 78% of the drive (at 28ms and 39ms respectively). Those points are always there and I don't know what that means. I have another forum post inquiring about it.

Now here are my CrystalDiskMark results.



And finally here is a CrystalDiskMark result I found on the internet for the 4TB version. The WD4003FZEX. Notice that my results for the 1003FZEX are on par with this drive.




So... are these values actually okay for my 16ms Access Time WD1003FZEX ? Why are my values essentially the same as for the 4TB version of the drive which uses 5 - 800GB platters, as opposed to my 1 - 1000GB platter.

Xutnubu, did you ever find out if these Access Times are normal for these drives, and we don't simply have defective ones? From what I've seen so far (though there is currently little information out there), all these 1003FZEX drives are in the 16ms range.

Kramy, you seem to be the guru around these parts, what are your thoughts on my benchmark results? Is this a pretty good drive after all, regardless of the seemingly high Access Time?

Thanks.

By-the-way,

I should note that I'm using an old GigaByte EX58-UD3R motherboard, and it only operates at SATA2 interface speeds. Which I think is why my burst speeds are a good deal lower than what others are seeing on these drives. (Can anyone confirm this?)

I am in AHCI mode with the most recent Intel RST drivers I could find that are still compatible with an ICH10R chip set.

Don't know if this will be any help, as it's a blue and not a black, but if you want to compare it to another single platter WD drive.

Here's what the new 1TB Blue gets:

I guess the Black should have a quicker seek time, being a faster spinning drive.

See now I don't get that.

Those results for your Blue drive appear to be better than this recently released 1TB WD Black drive, which is purported to be a good deal better than their previous Black high performance drives. The Blue line being their middle-of-the-road model.

Have you done anything to adjust the performance parameters of your drive. I'm going to have to look around now to see if your results are typical. Blue drives are cheaper than Black and, in addition to the shorter warranty, are supposed to be lower performing than Black (let alone the most recently released Blacks). In fact, other than the higher Access Time, your throughput results in HD Tune are better than even the higher performing 2TB+ newest Black models.

I'd suspect my SATA2 interface, but my results seem typical of other WD1003FZEX drives that are using SATA3 interfaces.

I haven't done anything to tweak my HDD performance (that I know of blinksmiley.gif ).

Can't remember if I put it on SATA2 or 3, but it's definitely on Intel and not 3rd party chip.

Well I noticed that you were using HD Tune Pro which is version 5.00, and I was using the older HD Tune version 2.55.

I also notice that your screen shot said trial version, which made me realize I could get the trial version of Pro. thumb.gif

At any rate I downloaded it, and ran the benchmark. The results were basically identical to the non-Pro version. Although I am getting much better Burst Rates with the Pro version. Still not as good as I suspect they could be if I had a SATA3 interface.

Here are the results. Which are seemingly lower than your Blue drive.




Do you have any CrystalDiskMark results for your drive?

I want to see if basically Black is now just paying for a significantly longer warranty rather than increased performance over Blue.

Don't think my CrystalDiskMark results will be of much use as my drive is almost full.

Hmmm. Yeah.

I don't know how much impact having lots of data on the drive impacts the CrystalDiskMark results.

It would really surprise me if the Blue performance is on par with, or even better than the Blacks.

If that's the case, then it would seem Western Digital has found a way for consumers to purchase an extended warranty for similarly performing drives, and calling them "performance". devilsmiley.gif Best Buy must be jealous.

Didn't take a screenshot, but I do remember read/write being over 180MB when the drive was empty.

    According to Passmark's online benchmarks, the Blue is indeed faster than the Black.  The EZEX scores at 1107 while the FZEX scores at 987.
