Should I use PIO or DMA mode for protections?

[IceBreaker]

The subtleties of PIO and (U)DMA are WAY beyond my scope , but this I have read:

"[...] DMA gives you CRC checking for data going over the IDE cable while PIO does not"

In other words, DMA is better if error-correction is what U want.

Besides, just because data goes though CPU doesn't mean PIO is more precise - CD-reader/burner accuracy still remains the same...

Furthermore, using PIO during a burning session implies putting more strain on CPU - this would tend to reduce data flow to the writer, causing buffer level to drop and burn-proof to activate, thereby seriously slowing down the writing process.

Hope this helps...
