my question is what is the diff in the serial ATA and the ultraDMA hard drives is one better then the other ill be using an ASUS KT600 Model "A7V600 motherboard suports two UltraDMA 100/133 devies also the board has Onboard SATA/RAID: 2x Serial ATA with RAID 0,1 which one is the best IDE or SATA why is sata more costly of the two which one should i choose im sorry my english is bad thanks for the help

More about : ultradma sata

serial ata has a transfer rate of 150mb/sec im told, ultra dma is only 133 i think, i could be wrong about that though...anybody else?

There isn't a performance difference between an SATA or UDMA drive as long as the drives are otherwise the same.

SATA goes up to 150MB/s, on a 133MB/s bus. So it wouldn't make a difference even if it could!

But it can't, because the drives are only around 60MB/s. Even Raptors are only doing around 72MB/s continuous.

so in other words i wouldnt notice any difference in performance between an sata hardrive and the ata133 ide i have now?

Different drives have different speeds, but two otherwise identicle drives will have the same performance on either bus type.

I don't know how fast your drive is. Maxtor offers the same drive in both SATA and UDMA versions, with the same performance. So does WD.

If you buy a new drive that's equally fast to your old drive in every other way, SATA won't help.

well would it make sense to go with the sata for future possibilities? the sata drives i am looking at are almost the same price as ata133 ones im looking at, within 10 dollars most of the time. is the pc heading in the direction of sata in the future, or is it like the amr and cnr slots....which never caught on....

hum i know this might sound like a crazy question but i wana learn the motherboard says UltraDMA 133/100 is this the same thing as Ultra ATA 133 if so why do they put the DMA after ultra i am new at this been reading a few weeks i really wana learn this stuff so a ultraATA 133 will work with my board? please dont laugh at me guys and gals i really do wanna learn i thank each and everyone of you for your input:)

Sure, as long as you don't plan to demote the drive to an older board later on.

There are only three real benefites of SATA right now.

1. Hot swapability (need right power connector too)
2. Neater cabling (this is just about worth it)
3. Better drives available (raptor)

For you the only benefit is the neater cabling, and perhaps (but very unlikely) the hot swap feature.

Some day I'll be rich and famous for inventing a device that allows you to stab people in the face over the internet.

All non-Seagate SATA drives to date work with a SATA-PATA bridge so any benefits of SATA are unlikely to be visible. SATA drives from Seagate have true SATA controllers but don't outshine their competitors anyway. SATA is more a looking-to-the-future inferface upgrade rather than a performance upgrade. So no, you won't see a difference in performance.
