Thanks to everybody for responding.
First of all, we can all make educated guesses, but the fun part would be to actually do the benchmarks and test out the levels.
RAID 0 is just as fast as RAID 1 when it comes to read speeds. It isnt just made for write transfers. The only thing that could possibly be faster than a RAID 0 in reading is a RAID 5, cause usually you have 3 HDs or more accesing the data.
RAID 0 doesnt do well at small sizes and bad on larger ones. Thats all dependant on the stripe size. The smaller your stripe size, the better for smaller files, the larger the size, the better for big files.
I plan on purchasing the game today, so if anybody wants, just record your favorite mission, hopefully one that takes a while to load, and then, as soon as I purchase the game, ill test it out myself. Itll be fun.
Take care!
