Drive 81 is the brand new Western Digital Gold drive
Drive 82 is brand new
Drive 83 has been in use for a few years
Drive 84 is been in use for a few years and is a Western Digital Blue drive (spinning not SSD)

An interesting thing when running ReadSpeed with the /4 switch on the new gold drive is how slow a couple of the sectors were. See below:

@thenitch : We're not really able to draw any solid conclusions from those timings for spinning drives without looking more closely. Even with the maximum (/4) resolution, we're still asking for 4,096 sectors (2 megabytes) for each of those numbers. But it might well be that somewhere in those 2 megabyte blocks is a sector that's really causing some trouble.
