P4P800 and ATA question

Are you basing that statement on the physical read speed of the heads or on
a known controller limitation? It seems to me that regardless of head speed
the contents of the hardware cache can still be transferred at the full
speed of the bus, unless there is a controller limitation.

Note that no ATA drive on the planet transfers faster than
60MB/s.

I believe u are wrong. I asked the same question and was told that It would
support my single ATA133 drive by utilising one of the Raid controller
connections. I have been told this a number of times.
Also from experience yes it will be faster in 133 mode as opposed to 100.

Does the P4P800 (non-deluxe version) support Ultra ATA/133?

No.

If the P4P800 does not support Ultra ATA/133, what kind of improvements
would I notice if I bought an IDE controller supporting it?

None at all. Note that no ATA drive on the planet transfers faster than
60MB/s.

To the best of my knowledge, the parallel ATA controller on the P4P800 only
supports up through ATA100 (mode 5). (This reply is being entered using a
P4P800 non-Deluxe based system.) I believe that it's all the Intel
865PE/ICH5R system supports.

The third-party PATA RAID controller on the Deluxe is supposed to support
ATA133, but you specified non-Deluxe.

I can't say whether you'd notice any gain with an add-on PCI controller
card. The higher rate would only apply to transfers from the drive's cache;
no current drives come close to saturating the ATA controller. (I doubt that
they would even max out an ATA66 controller.) My Western Digital drives are
ATA100, so I have had no temptation to experiment.

I use an old Promise Ultra100TX2 card with the hard drives. I've kept it
mainly so I could continue using 5 IDE devices. If the onboard RAID
controller on the Deluxe doesn't use the PCI bus, perhaps it would be an
improvement over a separate card.

HTH.

be
an easy question but I have not been able to find an answer. The BIOS
shows
that the hard drive is in Ultra DMA mode 6, but Windows XP shows that it's
in Ultra DMA mode 5.

Ah
I am talking about the deluxe.
