Hi all

What's the difference between SATA and SATA2? Is SATA2 significantly better than SATA?

cheers...

hellonearthisman: SATA2 is twice as fast

On paper. Hard drive read/write performance is still less than the SATA1 interface capability but a SATA 2 drive is likely to be faster because it is newer.

I agree, the interface allows for twice the speed but the current HDD's just aren't currently capable of those sustained speeds. There's some fairly high burst and cache reads but not sustained. You get better higher throughput running simple raid 0 striping IMO.

You are quite correct. I had actually tried to Google this, but didn't get any helpful responses. God knows what it was I was actually asking, but I have now pulled up a multitude of answers to my question. Sorry for the waste of space...

Just to make sure though, I'm assuming this mobo supports Sata2?

Serial ATA II = SATA2

Has o/b raid controller which I would suggest utilising in a simple raid 0 striping config for speed as opposed to integrity

Well it says it supports SATA II under the specification tab for the product on the URL you posted...so one would hope so!

My SATA drive does 38M/s and my SATA2 does 75M/s

yet there is barely any difference in price between SATA and SATA2?

What are the drives? The difference in speed won't have anything to do with SATA.
Even in the same series of drive Seagate managed to slow some drives down with duff firmware.

There are many factors which effect HDD speeds and there are many ways to measure speeds. Generally if you have the same harddrive (aureal density, platter speed, cache) and same PC used for tests then all things equal you will see pretty minimal gains going from an SATA model to an SATA2 model currently - outside synthetic tests I doubt you would notice.

Without providing further qualifying your statement what your saying is about as meaningful as saying your 5.8L Holden is much faster when running on 98 than your 2.0L Honda on 96 and attributing the difference to the fuel you are using.

Hi, the drives are on two different systems, the speeds are the top end and without raid,
I don't thing the mechanic's are faster between sata and sataii drive head access speed,
Data read/write speeds are twice as fast.

Most drives sold are SATA2 so it's not much of an issue, I don't have raid, but would like a mirror.
I went with a 320g (so I can raid 4 into 1+Terabyte), I got once with the lastest cache and low access time oh and within my budget.

That motherboard looks kind of nice too. Make sure u get the 800mhz ram too.
