well... if you want the fastest continual performance, purchase a large hdd, and only use the fastest portion of it (before the first 70%), keeping the slowest portion of it unused for day to day accessing. that way neither the avg or min STRs from the total capacity even matter really. sure, if you only use the first 70% of a 1TB hdd, thats 300GB sitting unused (possibly even unformatted), but thats also the same 300GB that are only getting ~50MB/s+ for the min avg and max STRs. likewise, if you were to use only the first ~30%, youll get a consistant ~85MB/s+ from beginning to end. this is true for all hdds though, not just the 1TB... but the 1TB has so much capacity, that you probably wont miss the last half of it much at all, if it wasnt there to use really.
so if you were to half stroke the hdd (50% in use only), thats the fastest 50% that the hdd has to offer... also making it so the r/w head only needs to move half to total distance to access any data that might be on there. essentially halving the access times (eg, ~14-16ms 7200rpm full stroke becomes ~7-8ms 7200rpm half stroke). all in all effectively halving the amount of time it would take to do much, for a typical windows user (since the files arent spread throughout the whole capacity as it fills up, reducing the effects of, and need to defragment often, defragmenting also reduces the lifespan of your hdd by introducing additional wear and tear, so its good to limit how often you do if you can).
the same holds true for raptors, which have an effective 8-10ms full stroke, so half stroking one will result in a maximum of 4-5ms to read across any data contained on that partition, the same with quarter stroking (2-3ms), eighth stroking (1-2ms), etc. but raptors are also comparatively small, so most people dont consider that to be as much of an option, if at all. but again, the same relative performance improvements also hold true just the same.
