No problem.  man hdparm and a bit of cut n paste with the help of kwrite.  

Besides, what are friends for?

Later

Oh check this out.

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

/dev/hda:
 Timing buffer-cache reads:   1420 MB in  2.01 seconds = 707.98 MB/sec
 Timing buffered disk reads:  138 MB in  3.04 seconds =  45.46 MB/sec
bash-2.05b# hdparm -Tt /dev/hdb

/dev/hdb:
 Timing buffer-cache reads:   1392 MB in  2.00 seconds = 695.06 MB/sec
 Timing buffered disk reads:  152 MB in  3.03 seconds =  50.11 MB/sec
bash-2.05b#


My old 30GB is faster than my new 80GB drive.  Go figure.  Have to play with that one a bit.   :?

Now see these results.. change.. a lot.. when hd was not having other loads.. I am sure when i run this tests only from command line. it will also have little effect...

Code:

Timing buffer-cache reads:   128 MB in  0.41 seconds =312.20 MB/sec
 Timing buffered disk reads:  64 MB in  1.35 seconds = 47.41 MB/sec

Hi..
Same Disk , Same computer but new output.. Just changed the  OS, now on FEDORA

/dev/hda:
 Timing buffer-cache reads:   1176 MB in  2.00 seconds = 588.00 MB/sec
 Timing buffered disk reads:   86 MB in  3.00 seconds =  28.67 MB/sec
[ricky@mgosft2 ricky]# hdparm -Tt /dev/hda
 
/dev/hda:
 Timing buffer-cache reads:   1140 MB in  2.00 seconds = 570.00 MB/sec
 Timing buffered disk reads:  100 MB in  3.01 seconds =  33.22 MB/sec

Bauth another 160GB samsung SP1604N hardisk

Its output -->

Code:

/dev/hdb:
 Timing buffer-cache reads:   1160 MB in  2.00 seconds = 580.00 MB/sec
 Timing buffered disk reads:  178 MB in  3.00 seconds =  59.33 MB/sec

BTW.. my 40GB Western Digital says :

Code:

/dev/hda:
 Timing buffer-cache reads:   1168 MB in  2.00 seconds = 584.00 MB/sec
 Timing buffered disk reads:  142 MB in  3.03 seconds =  46.86 MB/sec

Umm.. not really a big difference !!

BTW.. there are many members here and only few have posted their drive's info !

Also I am using Kernel 2.6 opposed to that 2.4 last time.

/dev/hda:
 Timing cached reads:   1260 MB in  2.01 seconds = 628.21 MB/sec
 Timing buffered disk reads:  110 MB in  3.13 seconds =  35.18 MB/sec
wat do i do nw???

A backup hard drive (40 GB) (Pata)

Code:

/dev/hda:
 Timing cached reads:   1668 MB in  2.00 seconds = 832.88 MB/sec
 Timing buffered disk reads:  132 MB in  3.03 seconds =  43.54 MB/sec

And main drive on that computer: 120GB Sata

Code:

Timing cached reads:   1896 MB in  2.00 seconds = 947.20 MB/sec
 Timing buffered disk reads:  168 MB in  3.01 seconds =  55.79 MB/sec

Clearly Sata is better .. even being bigger, it outperformed Pata 40 GB.

Would like to see other posting about their HD performances!
