Promise SATA300 TX4 and ASUS P4PE mb. Other controller card recos?SATA300 too fast for this mb?

At present, I have a Promise SATA150 TX2 controller card in my system
with an ASUS P4PE mb.

I am considering adding a SATA 300 PCI controller card for a SATA-300
drive I have acquired in order to use it to the max, if in fact, it
would operate that quickly (but at some time in the future it will
probably be in a system that will use it at its maximum capability). Or
is this foolish thinking because the bus won't be able to handle
anywhere near the 3 Gb/sec that SATA-II is supposed to be able to deliver?

Does anyone know of any issues with the Promise SATA300 TX4? Any
experience out there with the Promise or any other add-in card that does
or does not work with this mb?

Are there buses that can even handle 3 Gb/sec burst speeds?

Thanks

SATA disks do not deliver 3Gb/sec. The bus can. But the disks
peak at around 640Mb/sec or lower, just like ordinary ATA disks.
You have fallen victim to some marketing lies....

Not very likely.

Right. And neither do the drives themselves.

66MHz-PCI, 64-bitPCI, PCI-X, PCIe, take your pick.

 

Nope, it can't either. That's just the clockrate is bits per second.
There is no easy conversion to Bytes per second. The data is burst
at 3Gb/s, along with all kind of command and protocol and serial
conversion bits.

Many disks today peak at higher than 64MB/s.

Right, so learn from that and don't next fall victim to Babblebot Arnie
who pulls facts from his arse and sees conspiracies everywhere.
