Okay I have a question. Im getting a new sata drive but the most my mobo supports is 1.5. I was wondering if I bought a 3.0 if it is backward compatible with a sata 1.5 setup? the reason I want to get a 3.0 is to be a little more future proof so when I have upgrade my mobo to sata 3.0 I wont have to buy a new drive to take advantage of the extra speed. So basically if I get a 3.0gig drive will it still work in my 1.5 mobo?

SATA 1.5 or 3.0?

It will work but you arent future-proofing anything. The interface speed on a new mobo might support 3 GB sata, but that drive is still the same drive pumping out only 60-70MB/sec.
If it makes you feel better, yes a new motherboard can take advantage of the increased interface speed.

THANKS hehe
I looked through the FAQ and couldnt find my answer but maybe I overlooked it.
If I did I apologize for having you waste three seconds of your life typing yes
BTW is there any settings I would need to configure in BIOS or anything or does it automatically configure the drive to run at the slower speed?

auto
Okay a little confused about what you said. I was pretty much in the know about the first standard of sata but I been outta the loop for a short while and out of the computer scene and all of this new shyt with sata is confusing to me. If I buy the newer standard of sata drives im not future proofing for the new system im currently peicing together? Im gonna get the 3.0 sata II standard now that I know they are backwards compatible so wouldnt that be better in the long run when I upgrade the mobo?

There isnt really an SATA drive that I know of that exceeds the limit of first gen SATA. If SATA can handle up to 150MB/sec, and your drive can only read/write at 60-70, then upgrading the spec to 300MB/sec changes nothing. It would be like getting a thicker garden hose without adjusting the water valve at all. Your hose might be 2x as thick but that doesnt mean the water flow has really changed.
I mean, I believe that the entire bandwidth available to the PCI bus is 133MB/sec (Less than max SATA speed), yet Ive seen someone running 15,000rpm SCSI drives off a 32bit/33Mhz (standard) PCI-bus SCSI controller and it simply owned everything.
You would be future proofing your system if you bought a motherboard that supported the newer spec, with the idea that you might get a drive one day that can take advantage of it.
Okay thanks for the explantion. The analogy was helpul. I was just confused with all the new sata jargon, I was used to the first gen sata drives because like I said ive been out the loop for awhile and kinda fell behind in the newest tech.
But I mean if the price difference isnt much it would make sense to buy the best drive that has the newest standards (sata II and 3gb "speed") correct since it is backwards compatible with my sata 1 1.5gb speed mobo? Thanks for your help guys.

Buy the newer drive because it uses better technology.
It has a higher platter density.
If all things are equal (rotational speed/cache/interface) a disk with higher platter density will give faster throughput because instead of (example here) the drive having to spin 1 revolution to read/write 1MB of data, it can read/write that 1MB of data in less than 1 spin.
Think of it this way, how many swapping of CD's would you have to do if you were to read 1GB of data? If its a CD, you'd have to put in 2 CD's. If it were a DVD you'd have to put in 1 dvd disc. They are the same size (physically) , but the density (capacity) of the data is higher on the dvd thus giving you faster input of the data (because your arm only puts in 1 disc versus 2 discs).
