I agree with you if the seek times are different. But assuming that they are similar, I think that drive B will have more throughput after defragmentation.

Further, Drive A should be even more affected by fragmentation since it combines longer seeks with slower transfers. I guess seek could be moot if you're talking a few ms difference + factor in the caching algorithm, but then it's raw throughput that would make drive B faster after defragmenting. Ouch, headaches can form quick contemplating the variables. Too bad there's no synthetic benchmark to test fragmentation effects. Bobby Heid wrote: > I would think so.
