i have a plextor m5p and i wanted to buy another one and put them into raid 0.
but when i checked the price a 256gb m5p was 131 while a samsung 840 evo was only £92
not only that but benchmarks showed the samsung with faster.
so i'm asking if it's possible to put the samsung and plextor into a raid 0 config and still get pci express/gigabit transfer speeds. so around 800mb/s to 10000mb/s rather than the 500~ im getting now. Will there be any problems?

Thanks,
