I just tested with a 2970 and it had no problems pushing 11+ MB/s when
transferring a 6 GB VirtualBox disk image. So it seems it does not have
the buffering problems of the 2960/3560/3750 family.

I tested between Gi0/1 and Gi0/3, so on the same ASIC. The switch was
with a blank configuration, except for "speed auto 100" on one interface
(Gi0/1). The software was 12.2(25)SEC2 LAN Base, but I don't think that
matters too much. It had 83 dropped packets from ~5 million packets.
