Faster read time possible?

Hey all,

Just put together my first build a few weeks ago. Everything went well no real troubles so far. I'm now in the process of learn to benchmark and tweak everything.

So...

I just ran HD Tune one minute and it showed:

Transfer Rate
Min - 123.4 MB/s
Max - 224.7 MB/s
Average 193.5 MB/s



I'm using 3 SAMSUNG Spinpoint F4 HD322GJ/U 320GB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive in RAID 0. I can't help but think it should be a little higher but then again I'm fairly new to the in depth computer world.

Is there anything I can do to boost performance of my RAID 0 set up?

Should I be happy with the results?

Was a minute long enough to determine a good speed?

Also, during the minute run it had a large down spike to the 125 MB/s range then worked it's way back up to around 190 - 200 range again. Is that normal?

Enough of my elementary ranting now. Feel free to prod. I appreciate any help. Thanks


The rest of my build is as follows:

-Antec 600 Case
-ASUS Rampage III Gene Mobo
-EVGA 015-P3-1480-AR GeForce GTX 480 1536MB 384-bit GDDR5
-Intel Core i7-950 Bloomfield 3.06GHz
-Mushkin Enhanced Blackline 6GB DDR3-1600
-SAMSUNG Spinpoint F4 HD322GJ/U 320GB 7200 RPM SATA 3.0Gb/s 3.5\"

sounds pretty normal.

I had a 3 drive raid 0 with seagate 7200.12's (500GB/platter) and they are still some of the fastest sata drives out there as far as transfer speed.

Read time is more like the access speed in MS which raid wont help at all usually.. or very little. About the only thing that really helps access times is a SSD or 10k rpm drive.

Those look like very normal speeds for that type of array and spikes and dips are common

My array was 400-250MB/sec with some spikes.

you have to realize that most of the time the transfer speed (mb/sec) isnt going to have as big an impact as access time.

also with a raid 0 and 3 older drives I hope you have a backup. doesnt take much for one to go fubar and poof you are done.
