I can confirm..just bought and tried (1 metre..) It works!.. curious: why doesn't it work longer than one metre? there are also 3 meters long cables and it would be convenient to remove the magma from under the desk and put it in the rack .. let me know, thanks

The longer the cable, the greater the skew (divergence in signal timing between wires). The SCSI protocol has ways to correct for skew, and negotiates lower transfer speeds when longer cables are used. The PCI bus does not have those abilities.
