S-ata

Max IDE data transfer speed = 133Mbps
Max SATA data transfer speed = 150Mbps

So, not really, although SATA is capable of faster speeds, it's just not available at the moment. (correct me if i'm wrong)

SATA is available on most new motherboards but SATA2 or the next generation is not available as far as i know
 
As I understand it, Techy's right. SATA drives are the future though and eventually motherboard technology will be available to take advantage of them.

Cables are smaller though, which is an advantage.

On the down side, it's very easy to break an onboard or ondisk SATA socket, that L-shaped plastic protrusion breaks off easily, so be careful, they won't take the rough handling that IDE drives will.

And as Techy said, if you're a boffin, please correct me about the data transfer rate assumption.

The smaller and neater cabling is certainly a big advantage, and SATA is pretty much an industry standard now.

The transfer rate is a significant increase if you are upgrading from ATA100 100Mbps, rather than ATA133 though.
 
Is there a noticeable speed diffrenece from U-ata?

I think so. Ultra-dma, various speeds relating to both optical drives and hard drives.

SATA = Serial

PATA = Paralell.

Which I understand.

As for the rest of it, I must confess I a little in the dark myself, though I think I have a basic understanding.
 
The transfer rate increase to 150Mbps (current SATA) isnt that significant yet, but when the next generation of SATA2 is released the transfer rate will double to 300Mbps (there are even romours of 450Mbps). But, the interface can still only transfer data in relation to the disks rpm and seek time.
 
The future of SATA holds great things for those wanting even more speed, as drives with 300 MB/second transfer rates (SATA II) will be readily available in 2005, and by 2008 speeds of up to 600 MB/second can be expected. Those speeds are incredible, and are hard to imagine at this point. Another performance benefit found on SATA drives is their built-in hot-swap capabilities. SATA drives can be brought on and offline without shutting down the computer system, providing a serious benefit to those who can't afford downtime, or who want to move drives in and out of operation quickly. The higher number of wires in the power connection is partially explained by this, as six of the fifteen wires are dedicated to allowing the hot-swap feature.

Yes!

Ultra ATA
A version of the AT Attachment (ATA) standard that supports burst mode data transfer rates of 33.3 MBps. To take advantage of these high speeds, your computer must also be equipped with Ultra DMA, a protocol that supports faster data transfer rates to and from hard disk drives.
 
Is S-ata a good investment now? or should i wait ?

Wait, in second half of 2005 SATA II should be available with all other things (64 bit processors / motherboards, BTX standard, PCI Express and hopefully OS, applications and games that will be able to use all potentials of 64 bit structure)
 
How much would a 120GB hard drive cost, if anyone knows...
