What Great Guys you lot are (Hard drive question)

What Great guys you lot are helping everyone like this I think its great and I much apreciate the help you lot have given me.
Now with that said my new problem is about hard drives and raid. I have a ABIT KD7 RAID motherboard and I was thinking of setting up a RAID. It states in the Manual that it supports UDMA133 only on the RAID channels. On looking at Hard drives on the web they are mostly ATA133 or Serial ATA or SCSi which the latter I am not interested in. Is ATA133 the same as UDMA133 or not. Also could I just set up a single UDMA133 on the raid channel just to get extra storage or does it have to be a raid with two or more drives. Will a UDMA100 drive work on the UDMA 133 channel or not and would a UDMA133 work on a UDMA100 channel, I realize you would not get the same performance but the final questions are just something that I have been wondering about.
Thanks for all your time and trouble. Kindest Regards Tony B.

The manual should tell you whether or not

In reply to: What Great Guys you lot are (Hard drive question)

the RAID controller will support ATA drives or ATA and ATAPI drives.

It depends on which chip that they use for the controller some only support RAID, some only RAID or ATAPI [a BIOS change to select] and some [like my old ASUS] support RAID, ATA and ATAPI.

RTM and look in the BIOS.

Question about the word "ONLY"

In reply to: What Great Guys you lot are (Hard drive question)

following UDMA. Could it simply mean that that is the only IDE bus that supports ATA [UDMA] 133 because their other chipset's IDE buses only supports ATA 100 [this is the case with Intel chipsets]. Basically because SATA is the next hard drive interface, so why waste design time to go to ATA 133 when their chipset already has ATA100 support.

Any IDE drive should work on the ATA133 bus IF the bus supports ATA in addition to RAID.

Hi There this is what it says in the manual. Chipset (Via kKT400 and VT8235) Supports Ultra DMA33, Ultra DMA 66, Ultra DMA 100 and Ultra DMA 133 protocol.
Supports Advanced Configuration and Power Managment Interface (ACPI). Then further down the page after Memory section there is a section saying. Ultra DMA 133/Raid (For KD7-Raid Only) "which is what my board is" and says Highpoint HPT 372 IDE controler. Supports Ultra DMA 133MB/Sec data transfer rate. I am still confused "not hard to confuse me" LOL is a UDMA 133 drive a ATA133 drive just by another name or are they different animals completely. Regards Tony B.

is a UDMA 133 drive a ATA133 drive just by another name. YES

You might also see it as UDMA 6.
