sil3112a SATA Controller, current status

[Wilkinson, Alex]

Soren, I know that TCQ stands for 'Tagged Command Queing', 
but how about NCQ ?

And how does one find out if their SATA disk is really using a
PATA-SATA converter chip ? smartmon ?

	Correction, the 74GB Raptor is still not a pure or native SATA device, 
	it still uses the marvell PATA-SATA converter chip. Its true that it 
	supports TCQ but thats the same old way as the IBM deathstars used, and 
	not directly comaprable to the new true SATA NCQ way of things.

	If you want 24/7 uptime, you *really* should be bying hardware of a 
	quality that matches that, the SiI3112 is *not* in that league, not even 
	close.
