Improving disk access

[patata]

I need to save data at disk at a transfer rate of 40Mbytes/s. I have 3 SCSI disks with rates of 32Mbytes/s. But I can´t save data at expected rates. Any help is welcomed. I'm using VC6.0 in a W2000 machine.
Thanx in advance.

Are your disks in a RAID setup? If not then only one is being written to at any given time. Even some RAID controllers don't write to more than one disk at any given time so unless you have a good (i.e. expensive) RAID controller your maximum throughput will be 32MB/s

Thank you for your kindness.

I have tried to mount a RAID using W2000 disk administrator. And I have got less performance than using the three SCSI sequentially.
One question: When I write to the disk its buffer is being used. So while it is writing I have got the control and I can tell to the other disk to write data. I mean, writing to disk is something asynchronous. If I’m wrong: why are typical “flush” functions for?
