CMC MAG M0, rated 16x. Just started selling here in Singapore, silvertop OEM.
Using flashed BenQ DW1600->DW1620 with B7L9 firmware, UDMA mode 2, 80-conductor IDE cable, single master onboard IDE, default Microsoft IDE driver. Only 12x (11.7x max real time speed), so disappointed.
Funny k-probe, high at the beginning, then flat all the way.
