Only two megs a second?  Anything reasonably modern (read: P2 and 
ATA/66) should be able to handle that.

Period of absorption?  If by that you mean "sustainable throughput", 
then no, disk size has almost nothing to do with it.  Bus speed, bus 
type, percent disk full, number of drives (if RAIDed), available buffer 
memory and filesystem behavior all contribute.
