Today's current generation products (SATA and PATA100/133) can sustain over 60MB/s datarates, and the next will probably be even higher. The drive that could only do UDMA/33 is probably of a disk technology around 15MB/s or worse. Today's newest drives are quite fast. --eric - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
