As you are running the Maxtor 500's, I'd imagine that the result you are getting could be about right. I have not seen the results from other Maxtor's to compare them.

It could be higher, depending on the controller you are using too.

Using onbaord controller which i have no idea what it is....

That guy is using 2 x Seagate 500GB Raid 0
His speeds are about the same as mine but how is his burst rate so high?

And his line is much less jagged than mine ?

Uses the AMD� SB750 controller. Not sure if thats attributing to your uneven speeds.

The burst speed is not something I would worry about. Its how fast your parts "talk" to each other. Better controller better bursts, RAM can make a difference too, I believe. Please correct me if wrong anyone.

Burst rate is essentially meaningless. Don't worry about it at all. Same with cpu usage - almost always this is wrong as reported by most benchmarking tools.

Your controller is limiting you though - as efly pointed out the graph shape tells you this.

What are the settings you used for the array (stripe size mainly). Also what caching and read-ahead options do you have set?

Umm

Strip size set to 128k

One sec let me go check the rest

Brb.....

Ok the rest is

Cache: Write Thru
Strip Size:128K

Couldnt see read ahead anywhere

Controllerconfiguration

AHCI HBA MMIO Base Adress.......

Thnx for help guys

set cache to write back then re-test.

most onboard controllers don't have read-ahead cache options, but just thought I'd check as I am less familiar with AMD chipsets.
