HD Tach Disk Performance

[Steevo]

What kind of performance do you get from your Raptors, Caviar, DiamondMax or Maxline series disks? On what controller? Stripe size or RAID type.

128Kb Stripe
RAID 0
Intel ICHR7 Chipset
2) Maxtor 300Gb Diamond Max 10's
NCQ Active

On a server at work here while it was still online.

Last time I ran it I got about 218mbps burst speed. I didn't save the screenie so if you don't believe me well... too bad. I also don't know what I set the chunk size as. I think it's at 64kb. I didn't know what the optimum was when I was setting up my array.

The controller doesn't support NCQ, but the drives do. And the burst speed and average are PCI limited. But the CPU useage is lower than most RAID controllers out, and lower than the Nvidia RAID.

why are you guys running RAID 0 with such large stripe lengths.

isnt it large stripe lengths better for large file transfer such as multimedia editing?

and smaller like 32kb for small files, like games and standard desktop usage?

In a world where most games are installed with one CD of data, but, I have found better performance with 128K on games and data serving, video editing, music editing, etc....


On Office and MS apps 64K tends tobe faster. I set this array up 6 times with two controllers and different stripe sizes to get the best of all worlds, low CPU usage, fast steady performance, no suspention or hibernation problems, and no bandwidth leeching by the nfarce RAID controller.
