2nd Gen SATA on a First Gen Computer?
OK, a Computer comes with it single SATA Hard drive, which I assume is a ATA150, 8 Mb cache 1st gen SATA drive.
Now if I put in a 2nd Gen 300G 16Mb cache ATA300 Hard drive in its place, would it
A) record at ATA300 speed?
B) Fall back to 150ATA speed?
C) Cause confusion that won't let me load the package of CD-ROMS that came with Computer?
I need to know.

the bus would only be 150mb/s but the drive will deliver nowhere near that
even my raid 0 array of 2 300gb 16m cache drives can only do about 100mb/sHey who turned sigs on?

You might need to FORCE it back to 150 MB/s mode (via jumper), but that wouldn't harm performance at all ... actual drive throughput is MUCH lower than advertized interface throughput.

ThanX for the answers, the bottom line of which is that i can use the SATA300 on the older connector. This is an advantage insofar as the SATA 2nd series are often easier to find on local sales are are the newer technology. Also I've bought a low-cost controller SATA150 PCI card to update another Computer. But by the time I switch over, they ,too, will be "yesterday's story" !
I seems that just about everything in computers -at least at this level--is not what it's touted to be.
For example USBII is touted at 400Mbps -- but actually runs at 200,100,50,25....2 or such, depending on the conditions.
Rarely are conditions so optimized that the touted "speeds" etc. are realized very often in the real world.
Ah! So the industry keeps us chasing our tails !
