It is still much higher that what I get with this driver.... I will figure that out sooner or later. Btw, your cards aren't Type M, right? However I use here a Type M card, and its likely to include an FTL inside, thus, it might explain the low speeds I get there partially... Best regards, Maxim Levitsky
