OK I read about SATA2 but forgot some details. I read it's 300mb/sec. which is great! Now, what I wanna know is if I get a pimped out mobo like this Asus A8N-SLI Deluxe nf4 will a raptor run at SATA2 speeds or just regular SATA?

Hard drives are limited mainly by their own internal mechanics. Your raptor will burst at maximum 130MB/s while SAT 1 standard is 150MB/s maximum. Your raptor will burst at maximum 130 and sustain at around 70MB/s and thats just how it is regardless of what connector is used. The only problem there ever is is when a connector is old like UATA or ATA66 or ATA 33 and you have a fast hard drive sustaining over 60MB or bursting over 100 and the connector will limit it.

So in lamens terms, hard drive speed is not dependant on cononection speed unless the connection speed becomes a limiting factor. Your raptor will run at the same speeds.

thank you sir! so until they come out with new HDDs that can handle speeds that high then SATA2 isn't gonna do anything for me huh?

Once the SATA2 boards are out, one would expect SATA2 drives that take advantage of the full potential will shortly follow. The only question is when? But although it is speculation, getting a SATA2 board now at least positions you for the future.

First, the current gen raptor is only SATA1 or 150MB/s, so even if you plugged it into a SATA2 controller it would only negotiate for 150MB/s speeds.

Second, if you did have a SATA2 version raptor, the burst would jump up to ~280MB/s. Burst is only the data coming out of cache. The actual drive performance is the sustained rate which is ~70MB/s for a raptor. SATA2 will not change that.

You don't even need SATA2 at the moment. The fastest drive in the world only does 98MB/s sustained (Maxtor Atlas 15K II).

No they wont. Hard drives are limited by their internal mechanisms. Sata1, 2, 3 or even a 4 are useless right now because no one can get a hard drive going even up to SATA1 speeds. Going beyond SATA1 with 2 or any future updates is pretty futile right now because as someone said, there only capable of going 100MB/s at the max right now commercially.

SATA 2 will be out when intels new 945 & 955 chipsets are out, and that will be when the new dual core smithfields come out.

Its not like they are charging an arm and a leg more just for SATA2. Youll get charged an arm and a leg more for the board that has it but that is for other reasons. I say if you have the means, wont hurt to have it. You dont know what kind of technological leaps they will make in the next 6 mos. to a year.

As Digitalphreak said, there is little to no harm in being forward thinking about this. If they aren't charging a premium price for it, get the new tech.

It's the same as LAN jacks, I think. Pretty much all decent motherboards come with Gb LAN connectors these days. Does anyone on these forums actually have a Gb router? I know that none of us have Gb uplinks with our cable or DSL lines. Yet most of us have the Gb jacks because they came with the board, even though we very well may not be able to use it to its potential throughout the entire lifespan of the board. I suspect SATA-2 will be the same. On decent boards, SATA-2 will simply be what you get. In time, SATA-1 will be relegated to the budget boards.

Veto and myself posted the way we did because the original poster sounded excited like SATA2 was going to give him a performance boost.

Sure, no one is going to complain about having SATA2 because it will be free on new motherboards. There is just no need for the speed yet (for desktop computers).

The command queuing will be interesting though. That may help performance in a multitasking environment with drives that support it.
