SATA speed?

is SATA that much faster than ATA 133 or 100? Can you notice it on hard drives? are the thinner cables really much better to use?
 
just cables.. but the other thing is the master/slave/cable select jumper that half the world still haven't mastered...
 
the main difference is that sata drives are the newer drives, and the drives themselves have better technology, and are therefore better. also, the cables are sweet.
 
SATA-II and SATA-I currently has no performance difference AT ALL

The harddrive is still teh bottleneck regarding transfer performance. Even bandwidth of the old ATA-100 is not fully utlised.
Currently drives transfer on average 50MB/s, with 70Mb/s burst speed. Still under 100MB/s

SATA-I 150MB/s, SATA-2 300MB/s are useless improvements
However, SATA drives do have better features and newer technologies such as higher platter density, quieter, minor performance improvements

Some drives now come with Native Command Queueing, which I hear is supposed to be a good thing.

But as has been mentioned, hard drives can't even sustain speeds of 100MB/sec. The ATA/100/133, and SATA 150 speeds are the burst speeds, which the hard drive only needs to maintain for a small fraction of a second. It can do this by emptying its buffer chip all at once, but the largest buffer I've ever seen in a hard drive is only 16MB. So empty that in a tenth of a second, and your burst speed could be perceived as 160MB/sec, but only for that short time period.

Yep. That's why I said extra functionality
I didn't mention it because it had gave me bad impression. I am not impressed by the prformance at all. In MOST cases there are performance drop regardless of whether the nature of benchmark was multi-tasking or not when NCQ is enabled.

In another words, I am not convinced to use it at all. Even if I buy a NCQ drive HDD, I am unlikely to enable the feature

Can you use ATA/133 and a SATA HDDs in the same system? No interference/conflicts?

Yep, I have 6 HDs in my system now. Its a mix of SATA/ATA100/ATA133 and all it all works in perfect harmony.

hey, how does that work? Did you connect 4 SATA on your mobo and two thru IDE?

No, 2 SATA, 2 on MOBO IDE and 2 on ATA133 PCI card. My othe IDE has my 2 burners. I can attach 4 more drives but I think 6 is enough for now. Just over a terabyte!
