Hi

I'm just waiting for delivery of my new Hitachi T7K250 (SATA) and other
system components.

Hitachi supply a "Feature Tool" to enable SATA II mode and also Spread
Spectrum Clocking.

I've not heard of Spread Spectrum Clocking. Is this another term for NCQ?

A review of the drive in customPC magazine said that for best performsance
NCQ must be enabled.

If SSC isnt the same as NCQ, does anyone know where I access the NCQ
settings?

I've ordered a new ASUS A8N-SLI Premium mobo but I've yet to find out if
it supports SSC.

Thanks for any info.

Ian

No. Spread Spectrum Clocking is to reduce
electromangnetic emissions from the equipment
(http://www.sigcon.com/Pubs/edn/jitterfreeclocks.htm)
and Native Command Queueing is to minimize the
time used for HD read/write head movement
(http://www.neoseeker.com/Hardware/faqs/kb/15,71.html).
