Question: On a computer here when first powered on the USB wired mouse is not recognised. The light under the mouse is not lit up. Other usb hub's and keyboards work fine. Disconnecting it and reconnecting it fixes the issue, even after a restart - after the pc is switched off for a length of time (for example overnight) the problem reappears.

I swapped the mouse, updated the bios and installed updated intellimouse drivers, turned of power saving on the usb ports. Any ideas?

Answer: 
Install Windows on the first SSD

Install Ubuntu on the second. This will automatically detect Windows 7 and set the boot order correctly.

Then boot into Windows 7. Open Run and type diskmgmt.msc. This will open the disk management console. In the bottom section of the console, select one of the empty data disks and right click. Then select "Add A New Mirrored Volume" and select the two data disks. Then format the new volume and you're done.
if you plan to do the system install on win7 and ubuntu, you should install win7 first and ubuntu later, as suggested by MarkM above.

then, for the matter, depending on whether you plan on using software or hardware raid, you should format the volume *after* ubuntu & windows 7 installed (to minimize the fuss associated with multiple disk sets while installing ubuntu) and adjust the set accordingly in windows (e.g. install the RAID card/raid set driver, etc.), and in linux. 

you need to note too, that the current kernel driver for ntfs is limited in terms of write support although it reads almost perfectly. check out ntfsmount ( <http://www.linux-ntfs.org/> ) if necessary.
