Get that DMA turned on. I've gotten 30+ meg per second on Fireball AS's, and slightly lower on LM's. Is your cpu an old pentium 233 or something? The buffer-cache reads seems rather low, indicating the memory is slow, which could mean an old slow machine, to me.
Once you get that DMA turned on, ( -d1 ) i bet your speeds will go way up. If that's a 30gb Fireball LM or AS, it's not ATA33, even the LM's were ATA66, the AS ATA100. Mike
