Zgadza sie 33MB ale z nosnika do kntrolera, lub jakos tak.
Ja z dyskiem U-DMA, Quantum ST 4.3 GB ma takie parametry:

CD-ROM Toshiba 6102 B (x24).
Dysk z plyta z U-DMA ma troche lepsze parametry:
Hard disk 1: 255 sides, 523 cylinders, 63 sectors per track = 4102 MB
Drive cache/bus transfer rate: 27842 k/sec
Data transfer rate on track 0 : 11441 k/sec
