Please Post Average Read Speed with HDTach

[LarryJoe]

Just want to get a feel of how my scores fair. I use an onboard HP66 ATA 66 contoller. Funny for me is that the average read for my 20GB 7200 Maxtor is 20.6 but my slower 18GB 5400 Maxtor is 22.3. The 7200 is my Primary HDD (OS, Programs, Games) and the 5400 is for mp3's, downloads and files.

Just curious, please post.

Thanks,

LJ

AVG for my Maxtor Diamondmax 5400RPM Dual 30GB Raid 0 drive : 27162.0 kps (in winME ... i know its better in 2k but i forget what exactly)
--------------------------------------------------------------------
After Defragging my drive (have not done it in months) ... i get
Average 49087.2kps on my Raid drives ...



AVG for IBM Deskstar 20.5GB 7200RPM ATA66 drive 21880.0kps


i have no idea as to why the faster drive is coming up as slower ... it seems strange. unless the 20.6 drive has some kind of acoustic thing going on that slows the drive to make it quieter

With, or without ASC checked? I have it checked and here are my results on a VIA 596B southbridge.

Maxtor DM+40 20GB 24.8MB/sec
Quantum Fireball Plus AS 40GB 29.8MB/sec

p.s. lj hows it goin?

 

[LarryJoe]

What's ASC? I use the HP66 contoller on my Soyo 6BA+IV mobo and there are not many options in Windows. DMA is always on when using this controller. I have never gone into the HP66 BIOS, maybe I should have a look see. I do know that the UDMA modes are correct and HDTach returns solid read burst scores of 60 to reinforce that the drives are running in UDMA66 mode.

It doesn't appear that my scores are that off relative to BurnItDwn's:

<< AVG for IBM Deskstar 20.5GB 7200RPM ATA66 drive 21880.0kps >>

drive, which is comparable to my Maxtor's. The drives are of the Diamond Max variety, but not the 40, faster, series. It is just bugging me as to how the 5400 drive can be faster. As far as config, the 5400 is alone on the secondary channel and the 7200 has a Zip internal slaved to it. I am not a believer of the the myth the chain will only run as fast as the slowest device. This is bad information carried forward from older bus mastering techniques.

Keep the comments and scores coming please.

Thanks,

LJ

[LarryJoe]

Seems in line with my scores, but 11.9% cpu seems high. My drives always come in under 5%. Maybe if I could increase the CPU util I could get it to 22-23

Can someone plz send me the .exe setup files for HDTACH? The main website seems to be down.. ;(

Incoming, 956kb.

thx

Ok on a Tbird 1ghz and IBM 45 gig 75GXP I get

random access time: 9.2ms
Read burst speed: 74.1 mb/s

CPU util: 20.6 % ???
What could be causing my CPU util to be so high?

 

[Radboy]

Have found that trying to use ATA100 protocol (i have CUSL2 + 75GXP) gives me high CPU util scores. This may be due to a glitch in the HD Tach bench or immature Intel drivers .. either way, I use ATA66 protocol (lose nothing). I'm waiting for MS to put out some ATA100 drivers, as they seem to be good at writing drivers.

 

[Impact55]

Yeah I'm using ATA /100.. hmmm

Hey LarryJoe,

I just updated my Highpoint drivers (now version 1.28) and significantly reduced CPU usage in the HDTach test:

HD Tach version 2.61
Drive: IBM-DPTA-372050 P76O
Access time: 10.9ms
CPU utilization: 3.6%
Burst speed: 61336kps
Average read speed: 22292

Driver info:
Hpt366.mpd 1.28.08222000
Hptpwr.vxd 1.24.03302000

Got the new drivers from the Soyo Taiwan site not the Highpoint site.

Good luck.

 

[Radboy]

This is the best HD Tach bench I've ever seen (not mine, Cheetah X15).

 

[peemo]

Hey LarryJoe,

Followup in case you're interested. I found that the newest Win2K drivers (ver.1.25 - erroneously labelled 1.28) for the Highpoint hpt366 dramatically decrease disk performance. I tested using Winbench99 and found tranfer rates cut in half! I made sure to reapply the Windows2000 registry hack for enabling ATA66 after installing the drivers but no help. I have gone back to ver. 1.20 for Win2K and am much happier with the performance. The newer drivers are good for Win98.

Cheers

 

[LarryJoe]

Hey Peemo,

Thanks for all the leg work there and keeping me posted. I actually went straight to Soyo after discovering the difference in my drives and flashed the mobo bios(ba5 - 1.28 HPT) and also updated to the 1.28 HPT Win98 drivers. I got them from the USA site.

Thanks,

LJ

When I had them in RAID 0 configuration, my drives burst rate was off the chart (only goes up to 80MBps). The average was about 40MBps.

Maxtor DiamondMax Plus 40, 30GB ATA100 on Highpoint HPT370 controller (KT7-RAID)

Random Access: 10.2ms
Minimum read speed: 17.1MBps
Max: 30.3MBps
Average: 28.5MBps
Burst: 77MBps
CPU usage: 0.0%

Of course this was only reading through an 8GB partition at the front of the drive. HDTach won't read the entire drive in one go unless there is one large partition on it.

 

[Mikewarrior2]

28000 Average read speed for me..

20GB 75GXP, Cusl2.

Uh.... ACS is Advanced Size Check. You'll get vastly different results by checking and unchecking that box. Nobody on this thread mentioned whether their results were obtained with ACS checked or not. Not very informative.

 

[Mikewarrior2]

&quot;Unchecked&quot;...



Mike

 

[LarryJoe]

OK, bear with me here, but where the heck is the ACS checkbox? I see nothing under the drive properties or my highpoint driver poperties. Under the drive I have synch data checked and disconnect. There is no DMA option as the hpt controller unables it by default.

Thanks,

LJ

HDTach My scores are ok for my drive I guess.
