    Oh. Ok! :-)

    But there is a striping-like effect (especially when u use n=8
    discs in one RAID-5 and when u do sequential read), so that the
    performance could be easily (n-1)*40MB/sec (which would be in your
    case 350MB/sec; my single ATA disc reads 40 or about 40 MB/sec).

    So I would say, that something in the ATA driver is sub-optimal
    and worse than before. But I do not know what... There are so many
    lines...
