SCSI kontra EIDE

[Karel Dudasek]

Kdyz uz tady mluvite az tak odborne, mohli by jste
uvadet i parametry HD, ktere pouzivate?
Vysledky jsou totiz zavisle i na disku a 
u IDE taky na tom, jestli pouzivate 32 bit. pristup nebo ne.
Jen tak z legrace jsem to spustil u sebe na IDE :

Nechci tady moc placat, ale mam ten dojem, ze i na SCSI muzete 
volit, max. rychlost pro jednotliva zarizeni a povolit zretezeni
prikazu. ( U Adaptec radicu je to soucast BIOSu)
