HDD Performance Numbers

Some users in this forum have indicated performance/interface problems with their units. I'd like check to see if this is standard across the Acer line or just limited to a specific model. If I could have everyone run HD Tune and report back the results from the Benchmark Tab and the UDMA modes in the Info Tab along with the notebook model that'll be great. We can then compare the results to other systems to make sure that they're running according to spec or see if there's any problems.

Even though I don't have an Acer, here's my test results for my old Toshiba Satellite 4320 (P3-600).

not very impressive numbers. i thought that the difference btw 4200 and 7200 would be more significant.
try defragment and rerun the test.

Macius,
You're burst transfer rate seems to be a bit low. Other users here with similar units get somewhere in the 70+ area. I myself on an old Toshiba is still faster than yours. You may want to try temporarily disabling/stopping some services in the background and try again (something like anti-virus or spyware detection s/w may slow it down).

Macius & Destfix,
Can you also indicate your Supported UDMA & Active DMA values as well. You can update your message by clicking on the pencil & paper icon above your message.

Thanks,

I changed the HD from 60g 4200 to 5400. I swear when I changed it, it said Hitachi on the unit. But the window at the top of HD Tune says Toshiba MK6022GAX ??

It seems all Seagate HDs have a low burst rate. What does that mean ?

 

Ok, got the new hard drive installed and Windows running on it tonight. Here is the screencap - http://nopeople.com/webfiles/Hitachi%20notebook%20drive%201.jpg

I was thinking about getting a new HDD for my notebook, my focus now shifted to Hitachi 7K60(HTS726060M9AT00) found @ http://www.hitachigst.com/hdd/support/7k60/7k60.htm , maybe someone has experience with this drive.

Maybe even one of the above drives is that drive?

 

Zebrab, check my posts above. I bought the same drive your looking at, here is a pic: http://nopeople.com/webfiles/IMG_0484-hard-drive-swap-sm.jpg

I don't have Windows on my Acer Ferrari 3000. But I do think I have a performance problem with the HD. I've run a benchmark that is known as bonnie++ in the Linux world. I post the results an my webpage at work. I'm not sure how to correlate my numbers with the numbers from HDtune.

Do you guys think I could put a 7200 rpm drive in an old IBM or would it be too hot.

Nice topic full of number but can someone translate this for me [:I]

Does it mean that faster HDD are ALWAYS better? Is the difference really significant between a 4200 and a 5400rpm HDD or can you feel the difference only by going up to a 7200rpm?

I have a new Acer 1414 wlci laptop. I was attempting the HDtune test as suggested in this forum, but I have received a Read Error 7 or 9 times which cause the test to abort. I have rebooted and defragged, but it does not seem to help. I have two days left to exchange the laptop where I purchased it if defective. Should I be concerned? Is the HDD going to go bad? Could a virus check or something be causing the read error, or is it a hardware problem. Any help would be greatly appreciated. The results for the 2 tests that did complete follow:

Is the low burst rate on seagate drives a major problem?

 

Acer aspire 1694

Seagate momentus 100gb 5400rpm

Minimum = 19mb/sec

Average = 30.2mb/sec

Access time = 16.9ms
Burst rate = 70.3mb/sec
CPU usage = 5%

supports and uses UDMA 5 and has an 8mb buffer

 

it seems like all seagate drives apart from the 100Gb model has an unusually low burst rate.

Toshiba 80GB 4200tr/min

min 8,1
max 27,5
average 22,4

acces time 19,2

It seems that Seagate ST94019A disk is giving abnormally low performance. Burst rate it gave for everybody who checked it is around 25MB/sec compared to 70-80 MB/sec for other HD types.

I have this HD and felt from the beginning that HD is a real bottleneck of my Acer's overall performance. I'm also annoyed by the loud sound it gives. But HD Tune error check or Seagate seatool tests don't show any problems with it.

Does anyone have any idea why it happens? Seagate website or anywhere else on the web don’t mention any issues with this HD. Would I be able to complain about it and replace my HD from Acer?

J. Zack Hoffman Admin. Assistant at UMass Lowell's Helpdesk

 

Hi, Im using Compaq V2000 series notebook. Here are my specs:

Centrino 1.6
40GB 4200rpm HDD
256MB RAM
DVD/CD-RW

Anyway, after running HD Tune, this is the result:

HD Tune: ST94019A Benchmark

Transfer Rate Minimum : 11.3 MB/sec
Transfer Rate Maximum : 24.1 MB/sec
Transfer Rate Average : 21.4 MB/sec
Access Time : 16.3 ms
Burst Rate : 25.6 MB/sec
CPU Usage : 2.9%

As we can see, the Burst rate is very very low. Comparing to my friend's 1 year old Acer notebook 30GB Hitachi HDD, it was still way lower.(He got a burst rate around 75.2MB/sec).

I really feel that my v2000 is really slow comparing to other notebook of similiar specs. Im suspecting it's because of the burst rate. And after reading this thread, i can see that seagate HDDs always have low burst rate.

Now, my question is that, if i get a new HDD, maybe a 40GB 5400rpm HDD(Cause i dont need a lot of HDD space) or a 60GB 7200rpm HDD, will i still be stuck with the 25.6MB/s burst rate. Is the burst rate a motherboard issue or a HDD issue? Because from seagate's website, it states it has a Max. External Transfer Rate (Mbytes/sec) of 100 and Avg. Sustained Transfer Rate (Mbytes/sec) of >31

Please help me out because i dont want to get a HDD and end up with the same results.

Thanks in advance!

 

Here are 2 runs of the exact same Seagate drive (5400 rpm, 2MB cache). The first one is from yesterday and the 2nd one is from today. I seem to get something different everytime I run it.

I've put hitachi 7k60 into acer travelmate 8103, and despite comparable results with native seagate 100gh 5400 rpm in hdtune(seek time is shorter and burst a bit larger) I get significant performance gain, faster system boot and shutdown, and much shorter map loading in games.

 

IC25N040ATMR04 is the hdd I have in my TM290. All the numbers in previous posts are confusing (not unusually so) me. I want to upgrade to a 7k60, 60gb hdd but I'm woried about it sucking more power than the 4200rpm hdd I have now. Hitachi's site says it's power efficiency is actually better than what I have now, which I find hard to believe (7200rpm against 4200rpm). Has anyone done a similar upgrade and noticed any differences in battery life in the 'real world'? ANy hekp would be great, cheers.
