[Michal Fecko]

AHCI je dobré využívať namiesto IDE/compatible módu napr. kôli NCQ alebo hot-plugingu.

[Michal Fecko]

Mozno koli WD, osobne preferujem SG, ale moj notebook uz prisiel s WD tak som ho teda nemenil,,, ake prepinace skusit na "tuning" pomocou hdparmu? a co sdparm? SATA disk cez AHCI sa povazuje alebo nepovazuje za SCSI?

[David Jaša]

Spíš něco v konfiguraci řadiče nebo taky mohl nějaký proces zapisovat zrovna když jsi měřil. Tuning nemám žádný, toto je výchozí Ubuntu 7.10. A od té doby, co se v kernelu stará libata i o ATA disky, tak už žádné ne-scsi disky nemáme.

Mam Debian Etch s 2.6.18 kernelom, skúsim skompilovať 2.6.24ku ako sa to bude spravať

jo, ten disk je pekne rychlej, ale vsiml jsem ze mi na nem zacinaj pomalu degradovat data a po blizsim zkoumani jsem objevil vadny sektory... no o kvalite disku to snad nic nevypovida, muze to byt treba tim jak mi spadl zapnuty notebook z postele (lezim, je noc, programuju, najednou rana jak z dela, koukam, venku svetlo a notebook na zemi ).
