root@blackbox:~# hdparm -Tt /dev/hda

/dev/hda:
Timing buffer-cache reads: 128 MB in 0.77 seconds =166.23 MB/sec
Timing buffered disk reads: 64 MB in 1.77 seconds = 36.16 MB/sec

thats on a default install of slack 8.1.. havent tweaked hdparm yet..

People may be interested in that HOWTO, which I wrote a while ago. BTW my results on my boxes are:

Code:
[root@ernie hlpdsk]# /sbin/hdparm -tT /dev/hda

/dev/hda:
 Timing buffer-cache reads:   128 MB in  0.53 seconds =243.64 MB/sec
 Timing buffered disk reads:  64 MB in  1.62 seconds = 39.62 MB/sec
[root@ernie hlpdsk]# /sbin/hdparm -tT /dev/hdb

/dev/hdb:
 Timing buffer-cache reads:   128 MB in  0.52 seconds =244.55 MB/sec
 Timing buffered disk reads:  64 MB in  1.66 seconds = 38.46 MB/sec
On ernie (dual 1.5GHz AMDs, Maxtor HDDs). And on lemming:

Code:
root@lemming shak # hdparm -tT /dev/hda

/dev/hda:
 Timing buffer-cache reads:   128 MB in  1.07 seconds =119.63 MB/sec
 Timing buffered disk reads:  64 MB in  5.61 seconds = 11.41 MB/sec

@hackers_

Yes, Mandrake 9. rc 2 also defaulted the HD I installed it on to that kind of speed, without the hdparm tweakign needed, as did RedHat 8.1 beta 3. I think the newer kernels are supporting my chipset better, especially the IDE.

mine are slightly above average for IDE.

[root@schrock321 joe]# /sbin/hdparm -Tt /dev/hde

/dev/hde:
Timing buffer-cache reads: 128 MB in 0.27 seconds =474.93 MB/sec
Timing buffered disk reads: 64 MB in 1.11 seconds = 57.48 MB/sec
[root@schrock321 joe]#

asus p4t, 7200 rpm maxtor running on a pci ide adapter card.
i found it runs faster actually 2x faster using my promise pci ide adapter card verses using the onboard ide. something kinda cool to know.

[root@omega root]# hdparm -Tt /dev/sda

/dev/sda:
Timing buffer-cache reads: 128 MB in 0.38 seconds =337.84 MB/sec
Timing buffered disk reads: 64 MB in 1.76 seconds = 36.37 MB/sec

This is using a Fujitsu MAP3735NP Ultra 320 10KRPM SCSI Drive

Are these results low? Is there anything I can do to improve them? Thanks!

EDIT: I'm comparing the SCSI results to the results from my laptop running RH 8.1 Beta:

[root@psi root]# hdparm -Tt /dev/hda

/dev/hda:
Timing buffer-cache reads: 128 MB in 0.35 seconds =365.71 MB/sec
Timing buffered disk reads: 64 MB in 2.54 seconds = 25.20 MB/sec

The laptop has a IBM Travelstar 40GNX, which is quite a good hard drive, but the SCSI drive should blow it away.

Hello root,(Jeremy)
i had test this three times with every after few minits,
it seems look like this,
it this good??


/dev/hda:
Timing buffered disk reads: 64 MB in 10.04 seconds = 6.37 MB/sec
[root@hylix root]# hdparm -t /dev/hda

/dev/hda:
Timing buffered disk reads: 64 MB in 4.89 seconds = 13.09 MB/sec
[root@hylix root]# hdparm -t /dev/hda

/dev/hda:
Timing buffered disk reads: 64 MB in 2.87 seconds = 22.30 MB/sec

Welp, Here ya go with my results.

/dev/hda:
Timing buffered disk reads: 64 MB in 4.93 seconds = 12.98 MB/sec

Not very fast.. but it runs fine on my IBM Thinkpad 600X with it's kickin 10 GB 2.5 " HD. Not sure of the controller.. but I'm sure it's nothing special. Not SCSI of course. I will post my K7 2GHZ computer tomorrow. =)

Hello
IDE hd:
Timing buffered disk reads: 64 MB in 2.44 seconds = 26.23 MB/sec

this is a 20GB UDMA66 drive on the onboard controller (UDMA 33).

2nd IDE hd:
Timing buffered disk reads: 64 MB in 3.30 seconds = 19.39 MB/sec

This is a 20GB UDMA66 drive on a Promise ATA100 controller, and its slower, not sure whats going on there. Its faster under windows.

3rd HD:
Timing buffered disk reads: 64 MB in 2.30 seconds = 27.83 MB/sec

This is a Quantum 7200rpm U160 SCSI drive on a 19160 adaptec controller. Only just faster than the onboard IDE. Does over 44MB/s under windows.

And for fun my IDE zip drive.
Timing buffered disk reads: 64 MB in 145.39 seconds =450.76 kB/sec

Slow...

Cheers,
Sniff

Missed one out...
Timing buffered disk reads: 64 MB in 4.91 seconds = 13.03 MB/sec

This is an old 10Gb UDMA drive on the onboard controller.

Those benchmarks are normal, and it is normal to have a Windows benchmark different as it reports a figure between what the -t and -T figures would give in Linux. I do nont think you can get much better for what hardware you have now than what you have. The PCI and IDe busses tend to run at the same rate on your board, so throughput from cards will massively slow down from card to CPU adn be faster from CARD to HD-- thus the results will be close to the same except for buffering advantages from being able to chunk reads bigger with bigger buffers on HD mech-- the 66 will have a smaller buffer than the SCSI, so the SCSI will be tib faster in actual average throughput as bigger chunks are being bursted through PCI bus for bigger files. And the SCSI is a tib faster because to card it si more effective-- same HD and same card in faster box would be faster some, same HD directly connected to a motherboard with onboard SCSI of your sort would be faster yet. Also, do you know what CPU you have, as soem of those boards actually have UDMA 66 controllers and the HDs of that gen actually have circuitry that uses cable check to tell to run at UDMA 33 or 66 or use a utility to change from one to other bus speed.

Here are the hdparm results for 2x Maxtor 60GB 7200RPM:

First disk
/dev/hda: Timing buffered disk reads: 64 MB in 1.64 sec = 39.02MB/sec

Second disk
/dev/hdb: Timing buffered disk reads: 64 MB in 1.60 sec = 40.00MB/sec

That is reasonable-- the drives of that size that are IDE tend to be about that, and the only thing I have seen higher of the 7,200 RPM ones was a WD with an 8 MB buffer-- and it transferred about 6 MB\sec more than yours and my 2 MB buffered drives on the hdparm benchmark-- on BIG files, it was visibly faster, things like large scans, etc.

I'm using a Dell Inspiron 8200 running Mandrake Linux 9.1.

The hard drive is an IBM 60GB ATA100 spinning at 5400 RPM. The results from the command 'hdparm -t -T /dev/hda' are as follows:

/dev/hda:
Timing buffer-cache reads: 128 MB in 0.38 seconds =336.84 MB/sec
Timing buffered disk reads: 64 MB in 3.08 seconds = 20.78 MB/sec

Good stuff

This is a single Seagate Cheetak 15k U320 SCSI drive.
(Pretty dang good for a single drive imho...)
SCSI Controller is the integrated U320 controller, running at 80 Mhz (i.e. the scsi bus is running at 1/4th its normal speed), on a Supermicro X5DA8

[fenix@gandalf fenix]# hdparm -t /dev/sda

/dev/sda:
Timing buffered disk reads: 64 MB in 2.00 seconds = 32.06 MB/sec

Enjoy =)
