SATA2 is an automatic bottleneck...

post #1 of 30
Thread Starter 
If you notice, even though the SATA2 has a 3Gb transfer rate, the south bridge can only transfer at 2Gb!

Yeah but SATA2 drives can't reach 3gb/s speeds anyways.

Ya they've been doing that on alot more than HDD's, ever since the beginning of home computer time. They'll say a device can do whatever, and maybe it could, if the rest of the hardware/drivers could push it that fast, but it can't and never will. It's marketing fluff, to make their products look better than you'll ever actually get from them, borderline false advertising in my book. Kinda unfair really some of the bs they can get away with. They basically lie to consumers but it's not illegal since the device actually could do it (supposedly), if we lived in Never Never Land I guess and fairies sprinkled pixie dust on them.

They do that crap on everything from HDD's, to CD/DVD drives, to well...pretty much everything in your computer. In the case of CD/DVD drives, they'll say it's a 16x burner, even though your burn will probably suck or make a coaster with alot of drives and most medias. Not to mention it won't burn at 16x for almost all of the burn anyway. Same with the reading discs part. It will start at like 6-7x, and slowly get faster on a dual layer disc, reaching almost 16x (if it's the fastest ripping drive on the planet) only at the middle of the read, then slowly get slower again until the end. They'll embelish, exagerate, and pretty much outright lie in order to make themselves and their products look better. Somehow, the law enables them to do this which is rediculous I think. The computer industry is like the Empire, sitting in their Death Star, charging the cannons to zap your wallet . And watch out for Darth Vader!! He'll entice you to the dark side with promises of untold speeds and performance, muhwhahahah!!!

Eh....lol

That made one of the biggest differences in my rig was going from a 5500rpm 2mb cache IDE drive to my new WD Caviers, lol, but I'm sure your IDE isn't hurting quite that bad

Same thing is often the case with graphics cards. People are running out to buy these fancy 7800 GPU with memory bandwidth of 54.4 GB/s. Heh, the PCIe can only transfer data to the chipset at 8GB/s

LOL....when I bought my 7800.....the bandwidth capability never once came into play on my decision. I said, "they can do 90K in Aquamark3 and play FEAR, BF2, CoD2 ect on all max at 80+ fps and it cost 285 dollars!"

LOL

In the picture that you have attached, which i assume is for intels new 975x chipset it does say the transfer rate to the southbride is 2 GIGABYTE while the transfer rate they are advertising to the hard drives are 3 GIGABIT there is a huge difference there are 8 BITS in one BYTE so IMO this is legit advertising you can tell this because MB is megabyte and mb in megabit. and sata2 has some crazy burst speed specialy with 16MB buffer.

i have heard of 300gb/s burst speeds on the hard drives i have but i need to get a new motherboard (975x) with onboard sata2 insted of a crapy RAID card before i can reach those.

Your comment is a common misconception. Sata2 standard does not mean 3gb/second and is not required. Yes, most of the newer Sata2 drives offer 3gb/s speeds, but that is not part of the Sata2 standard. (same thing with NCQ)
