Lightroom "disk activity" on the wrong drive - can someone explain?

Hi,
I am a professional photographer & am trying to optimize Adobe Lightroom for processing RAW files as fast as possible. Presently, I am trying to decrease the pause I have each time a new photo loads into the develop module (this is my biggest editing bottleneck).

Here's my system specs:
OS Win-7 64-bit
RAM 32G
CPU i7-3930K
Windows is installed on C:\ (SSD)
Windows paging is managed by the system, and usually appears on C:\ (SSD)
the Lightroom catalogue is on D:\ (SSD RAID-0)
the Lightroom Cache is also on D:\ (SSD RAID-0)
the RAW files that Lightroom accesses are on E:\ (SSD RAID-0)

My confusion is over the way Resource Monitor displays the "disk activity" at the crucial points (when Lightroom loads a new RAW photo). The "storage" window lists drives C, D, & E as as most active during this time (according to the Active Time(%)), which seems right...

However, "disk activity" lists the system and lightroom as reading files from "H:5\file_path_etc" at the highest rate. I am concerned that this means Lightroom and system are using cached files on the H:\ drive, and my H:\ drive is a slow 7200rpm HDD... Or maybe I'm not reading the "H:5\file_path_etc" tag right. (drive H:\ doesn't have these files on it anyway, unless they are there in a cached form (?)).

I also see a similar thing for "disk activity" on "H:0\file_path_etc" for the following files:
1) the Lightroom catalogue, which should be on D:\
2) the Lightroom Cache, which should be on D:\
3) the RAW files, which should be on E:\.
These last examples of disk activity however don't occur when files are loading, so I'm not really concerned about them.

Could someone interpret what "H:5\file_path_etc" and "H:0\file_path_etc" mean and what might be going on? I'll attach a screen shot of what Resource Monitor lists during the period when I've been loading files consecutively (bride & grooms names are blacked out).

Thanks!

UPDATE:

OK, so I think I've solved this one. H:0\ is simply Windows 7's way of referring to the D:\ drive in a RAID-0 array on my computer, and H:5\ is Windows 7's way of referring to the E:\ drive in a RAID-0 array on my computer.

Bummer. I was hoping for a speed increase in the way Lightroom behaves. I'll need to look elsewhere, it seems :-(
