32 bit vs 64 : HDD / SSD read-write speed

[wsx]

32 bit vs 64 bit operating systems, both installed on 64 bit hardware, which one is faster for reading / writing internal hard disk drive / solid state drive?

Underlining is for grouping.

Unless you are looking at the benchmarks, I doubt that you would notice any appreciable difference. The bottle neck is the speed of the I/O device. Of course SSD will be faster than HDD. To quote Spock: "A difference that makes no difference, is no difference"

there should be no difference at all drastically out of the boundaries of error.

I've found some benchmark results:

1GB RAM, Core2 1.83Ghz:

Dbench is giving slightly better results for 32, PostMark giving slightly better for 64.

4GB, i7 1.6Ghz:

No Dbench, PostMark is giving way better results for 64.

64-bit is the way of the future. Its performance will only get better.
