can you run raid on IDE drives?? im not planning to anyway, but can you??
Wiki concerning Raid;
Around 1997, with the introduction of ATAPI-4
(and thus the Ultra-DMA-Mode 0, which enabled fast data transfers without involving the CPU
and thus resulting in much less CPU utilization) the first ATA RAID controllers were introduced. While RAID technology was available for a long time by then, it always required SCSI
hard drives, which were considerably more expensive than IDE hard drives. IDE hard drives were considered for the consumer market, whereas SCSI
hard drives were aimed at the server and high-end computing market. SCSI
technology was not only faster at that time, but had other advantages as well (up to 15 devices on one bus, independent data transfers, hot-swapping
, much higher MTBF
). However the vast difference in price, and the increased performance of ATA drives, led to the developement of ATA RAIDs. Because RAID systems always need more than one hard drive, the price advantage of ATA drives made it possible to build RAID systems at much cheaper costs than with SCSI. Those cheaper RAID system made their way to the consumer market, where the users wanted to take advantage of RAID systems (e.g. the fault-tolerance with mirroring), but did not want to invest in expensive SCSI drives. With the ongoing performance improvements, the RAID functionality was not any longer realized in specialized hardware, but in software. This led to ATA RAID controllers, that provided just the logic for the connection to additional ATA drives. In the early 2000s nearly every advanced consumer mainboard
provided ATA RAID functions onboard.
So yes you can run IDE raid but with the abundance and low price of SATA, why would you want to?
