Not really - a PCI Promise IDE controller is about $100. And it will work at ATA-100 speeds even on older machines. I have one in a celeron 433 that would only otherwise do ATA-33. Hardware IDE raid cards on the other hand Are expensive. -Original Message- From: Volker Kuhlmann [mai

Yes you will get a substantial improvement when you dedicate an ide channel per physical disk. When sharing, only one operation can be performed at a time ( on IDE - but not SCSI or SATA istr ), which results in the halving of performance on each disk that you have seen. However, make sure that th
