 Posted: Sat Dec 27, 2008 7:17 pm Post subject: Is my hard disk too slow (broken)? {hdparm test} |
 |
|
Ok I've got a "Compaq Presario 2532EA".
| Code: |
# lspci (most important entries)
00:00.0 Host bridge: ATI Technologies Inc RS200/RS200M AGP Bridge [IGP 340M] (rev 02)
00:01.0 PCI bridge: ATI Technologies Inc PCI Bridge [IGP 340M]
00:10.0 IDE interface: ALi Corporation M5229 IDE (rev c4)
|
The hard disk is an "IBM TravelStar IC25N030ATCS04-0" (4200RPM UDMA-100).
And it's correctly set to "*udma5"
Here's the test:
| Code: |
# hdparm -tT /dev/hda
/dev/hda:
Timing cached reads: 508 MB in 2.00 seconds = 253.81 MB/sec
Timing buffered disk reads: 56 MB in 3.08 seconds = 18.16 MB/sec

gionnico,
Its a little on the low side for a 2.5" 4200 RPM drive but not a lot.
I would have expected low 20Mb/sec.
hdparm is not a good tool for hard drive speed tests as its affected by whatever else your CPU is doing.
As a general indicator, your setup is ok.

Hmm I've tried different times and also within partitions with very little different results. The one above is aligned with other tests I've done.
Also I was doing "nothing" (at least from the I/O side).
So it's not much but it isn't the cause of the poor performances sometimes I see in my computer.
Thanks for your analysis, NeddySeagoon.  |
