Was very surprised at first when seeing the results you all were getting when I noticed the date of the thread
Very nice thread indeed

episode96, why is your drive reading ~2GB instead of ~100-120MB like everyone elses?

15GB quantum, 3 years old, without any tweaks, kernel 2.4.22, home made
# /usr/sbin/hdparm -Tt /dev/hda

/dev/hda:
Timing buffer-cache reads: 128 MB in 2.37 seconds = 54.01 MB/sec
Timing buffered disk reads: 64 MB in 5.55 seconds = 11.53 MB/sec

after hdparm -c 1 d -1:

/dev/hda:
Timing buffer-cache reads: 128 MB in 2.09 seconds = 61.24 MB/sec
Timing buffered disk reads: 64 MB in 4.18 seconds = 15.31 MB/sec

Well, the thread was started a long time ago, but there are many recent posts. I am also trying to figure out how your drive managed 1720mb's....

I have a new 7200rpm Maxtor with an 8mb cache and this is my results:

bash-2.05b# hdparm -Tt /dev/hda

/dev/hda:
Timing buffer-cache reads: 1576 MB in 2.00 seconds = 788.00 MB/sec
Timing buffered disk reads: 172 MB in 3.02 seconds = 56.95 MB/sec

Ok. This is weird as hell I was all ready to post the usual 130mb's or so, and I wound up with 1576. Here is the results I posted last week on this same drive:

bash-2.05b# hdparm -Tt /dev/hda

/dev/hda:
Timing buffer-cache reads: 128 MB in 0.30 seconds =426.67 MB/sec
Timing buffered disk reads: 64 MB in 1.14 seconds = 56.14 MB/sec

Oh, I see. For some reason hdparm decided to use 2 full seconds today, rather than .30 last week. Episode96 also has 2 seconds.

Anyone know why that is? Was hdparm changed during a recent update maybe? I just updated Slack a few days ago...

I just bought the same Maxtor 7200 w 8MB cache and had been wondering if I was getting the actual performance it is capable of- here's my results:

Timing buffer-cache reads: 128 MB in 0.24 seconds =533.33 MB/sec
Timing buffered disk reads: 64 MB in 1.45 seconds = 44.14 MB/sec

close enough i guess, but are there options to be played with that could increase this to your results?

Try 'man 'hdparm' to get a list of options you can use with it. There is also a decent tutorial here

We might not get the same numbers due to possible differences in the rest of our hardware. i.e. system bus, cpu, IDE controller, etc.

here goes a highly embarrasing post...

17GB Seagate ST317242A , udma2, 5 years old falling apart, root filesystem
/dev/hda:
Timing buffered disk reads: 64 MB in 13.50 seconds = 4.74 MB/s

10 yr old Quantum Sirocco 01700A mdma2, 1700MB, my /home, aquired it last week from my sisters buggered-up PC
/dev/hdd:
Timing buffered disk reads: 64 MB in 12.33 seconds = 5.19 MB/sec

WTF!?!?!!!!?!?!
the older secondary IDE hdd is faster than the new primary master???
must be a bottleneck somewhere

Cheapass Toshiba laptop:

Timing buffer-cache reads: 1476 MB in 2.00 seconds = 737.63 MB/sec
Timing buffered disk reads: 72 MB in 3.02 seconds = 23.85 MB/sec

Better than expected - Redhat doesn't do dma and doesn't let me enable it for some reason With gentoo things worked fine.

Timing buffer-cache reads: 1168 MB in 2.00 seconds = 584.00 MB/sec
Timing buffered disk reads: 8 MB in 3.51 seconds = 2.28 MB/sec <-- haha the power of not getting DMA to work... Its an Western Digital 'cuda' 120GB 7200rpm 8MB cache

Anyone got any advice for getting this to work?
