Ah. I'm wondering about Nero's test methodology; what may be fast
when accessed alone may be slow when accessed concurrently with other
volumes, when that involves head travel between these.
Normally, the details of where drive letters actually are is hidden
and irrelevant, but when going for performance, you need to keep those
details in mind. Let's say C:, D:, E:, F:, G:, H: are all logical
volumes on the same physical HD, created in order with these sizes:
C----D--E----------F-------G----H--
D: and H: may be equally fast, when accessed alone, as they are small
tight volumes. But in the context of constant accesses to C:, D: can
bve expected to be way faster than H: because the head travel is less,
between C: and D:, than between C: and H:
If OTOH the drive letters are not in order...
C----H--E----------F-------G----D--
....then the reverse might apply.
Let real-world mileage be your guide - and I suspect you'd find the
fastest volumes in the following 2 x HD scenario would be C: and D:
HD1 C----E----------F-------G----
HD2 D---H--------------------------
ideal for experimentation!
H:\ is on my local disk. I chose it after I made a drive speed test by "Nero
6.3" and found it the fastest one among C:\ , D:\, E:\ ....
I did this after reading this article:
