HDtune for 320GB 7200RPM WD. Is this normal?

Just received WD 320GB Black 7200RPM today. I run HDtune and found that the burst rate is around 51MB/sec only, while I see others have 100+MB/s. Is this normal?

 

Strange. Look at my 500GB Scorpio Blue 5.400 rpm.

Your CPU usage is high..

 

Would help to know what you are running it on.
Also, what processes you are running, as many can interrupt the hard drive and cause bad benchmarks.
Try an ATTO bench, but again, if you have processes that interrupt the hard drive (indexing, background defrags, whatever is reading/writing to the hard drive) will affect the score negatively.

 

The chart actually looks fine. 60MB/Sec is about the norm for the WD3200BJKT. Its faster than the 5400rpm cause it has faster seek times.

This is fresh install Vista Ultimate. There is nothing running in the background. When I go to Windows Task Manager, the CPU is only running between 1%-4%. Not sure why it shows so high in HDTune.

 

Check my hdtune below. I run Vista SP1, why my burst rate is so low and lower than max transfer rate? And this is 7200RPM, why the 500GB 5400RPM is faster?

 

Because 500GB have higher areal density which means the data is available to be read on the platter, so the much dense the disk area the fastest the info is retrieved by the heads.
I'm actually bummed by dense HDD because those are not as quiet as single platter drives

 

the 500gb 5400rpm drives are not faster than 320gb 7200rpm drives. The 500gb may have slightly higher bandwidth, but the 7200rpm drive has faster seek times, thus faster loading. A 7200rpm drive will outperform a 5400rpm drive in this case.

Otherwise your performance value look to be perfectly normal

Hi all, what I don't understand is:

1. Why my burst rate is very low even compared some older/slower HDD?
I've seen many has burst rate 90MB/s and some are over 100MB/s? Is there anything wrong with the SATA controller host?

 

burst rate really does not mean very much. In simplistic terms, burst rate is the speed in which your drive can open random files on the disc. The burst rate will change from time to time, in most benchmarks. It does not represent how well the drive actually performs.

The burst rate seem to my untrained eye to perhaps be PC dependent?? All the HDD's I have tried in my Sony SZ have had high burst rates. My current HD Tune result is as follows:

 

So the one with FFS really IS slower than the one without? I mean, mine does about 70MB/s average, without FFS, i don't think FFS slows down by ~10MB/s ?

That benchmark seems a little slow, try shutting down everything before you benchmark the harddrive, otherwise you did it wrong, other things running at the same time will give bad results.

Here's my WD3200BEKT drive that's been running 3797hours and counting! (158 days of 24/7 use )

 

Yes it's dependant on the computers motherboard/chipset and not the drive itself Mostly.

However burst-rates are not important!

 

This is mine.
I wonder what caused the huge difference of burst rate
XP will get better result?

 

Read above your post!

 

If same chipset PM965/GM965 (ICH8M), should get the same result?

HD Tach indicated my burst speed is 199.8MB/s; faster than SATA 150.

I know burst speed will not affect the hard disk actual performance but this just a mystery to solve

 

Burst rate isn't bottled by the SATA transferrate, so you can get any speed there, i had 1900MB/s burst on my previous raid0 with 3x harddrives.

It's nothing major to solve though, nothing that may be needed to know anyways as there isn't anything to "get" from knowing it!


See here for example (that's my raid0 i had on my desktop before):






If you have the same operating system togheter with GM965 on another computer, with the same drivers, yes, it should show the same results.
