If you mean Mbps then you are already above it. 100Mbps = 12.5MB/s give or take and both speeds are above that. I guess you probably mean 100MB/s though and that is only what the cable can take. If you take a T-ford onto the highway - can you go 130Km/h in it? No, the road is rated at 130Km/s but the car can't go that fast. Same here, the standard says you can transfer 100MB/s over the cable but the disk isn't fast enough to be able to transfer that fast. // Stefan -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (MingW32) iD8DBQFC5L/BBrn2kJu9P78RAkXKAJ4vc/xQ0Z8mA1ddo79+wC6NCFe5VACgl+j+ ceP+as8dx0uZs2W6xaYiMVc= =Of1/ -----END PGP SIGNATURE-----
