I know this is a vista NG..
and i know its not right thing to post a non vista issue here..
but i neet help..

i need to process large amounts of data in one shot sometimes..
( 4 or 5 gigs of photoshop CS2 files with lots of layers :( )

And i am gathering a new machine with tein opterons and so..
i need fast access and transfer times on hard drives becouse its the
bottleneck of the system..

i got 2 choices

1) 2x seagate Barracuda Sata II 7200 rpm.. on Raid 0
2) 2x Western Digital RAPTOR Sata I 10.000 rpm.. on Raid 0

As far as i know. sata I supports up to 1.5 gb/s
and as i read it on google.. best HD's are going 165-170 mb/s..
now.. is it something like
"Sata I hard drives have plenty room to improve, there is a huge space
between 170mb/s and 1.5gb/s so i can buy any fast Sata I HD i want"

thing..or is it just like internet connection

"-when you have 1024k DSL you get 25-30 kb/s download speed,
but if you think like i can do the same with 256 kb/s i can mostly do 30
kb/s
so i have plenty of room to go-"

I know, that kind of thinking can make you a fool bigtime...
anyway..
need your expertise :)

I have two systems. One system has 2X160gb SATA l in Raid 0 and the other
system has 2X160gb SATA 2 in Raid 0. The SATA 2 is only slightly faster. I
get performance rating of 55mbs of SATA 1 and 60mbs on SATA 2. I cannot tell
any difference in overall system performance. You are quite right. All the
hype about 1.5mbs and 3.0mbs is just hype. Hope this helps.
 
Hopefully you will get a response from someone with the 10,000 RPM. Gives
the potential of 1/3 higher performance
 
FWIW these are the results on my machine. Don't have Raptor

i go sata I samsung 120 gb at the moment..
i downloaded the program you use for testign hard drives and tested mine..
this is the result

HD Tune: SAMSUNG SAMSUNG HD120IJ Benchmark

Transfer Rate Minimum : 30.6 MB/sec
Transfer Rate Maximum : 61.4 MB/sec
Transfer Rate Average : 47.8 MB/sec
Access Time : 15.2 ms
Burst Rate : 81.7 MB/sec

its almost the same with your "HDT722516DLA380 Benchmark SATAII"

now does that means "its the hard drive that counst not wich sata it uses"?

i am confused here..

I would NOT compare with the Hitachi SATA II. It was the first one
available in my area and was a disaster from the beginning. It has had the
firmware upgraded to SATA II but I never have been able to get an operating
system to install and boot on it (SATA I or II modes). I use it only for
storage. OTOH I love the Samsungs. They are fast and quiet. As to your
original question, hopefully someone with Raptors will give you their
results so you can compare with the SATA II.
 
RGR that ..

Thanks for all the testing..

My new C2D desktop uses a couple of Seagate SATA-II drives
that have the Perpendicular oriented data. Using DiskSpeed32....
Access Time = 13.1 mS
Burst Transfer = 246 Megabytes/Sec
Average Transfer Speed = 89 Megabytes/Sec

As for SATA 1 or 2, it is all hype from everything I have read Drives are
getting super fast 15,000.

Personally I think an SATA 1 with a 16 MB cache will outperform an SATA 2
with an 8mb cache as long as they are both 7200.

Question, if I pick up an SATA 1 and get a converter that allows it to run
off the IDE controller, will it be slowing the SATA drive?
 
SATA is becoming better, but I would still recommend a SCSI system for
your purposes. Like a Dell Precision 490 system. You may add a second SATA
drive, but I highly recommend you run your system partition from a
SCSI-drive.
