Finally, probably won't make a whole heck of a lot of difference at all, but been needing a windows reinstall, a nice fresh non pooped up install of win 7 on my raid 0 crucials. Been putting it off and off as the GC firmware was always rumoured to be just round the corner.
Though, unless there was some massive degredation on the first install of windows, my results from fresh install till now, like 3-4 months later, same numbers entirely. Though windows does do a lot of unpacking and moving of files so its conceivable performance hasn't been what it should be since day one. Its still miles, and miles ahead of mechanical hd results with 30mb/s random 4kb writes, where my raided normal drives would get maybe 1mb/s, if lucky.
