I suggest you go take a look in the mirror. It will help you identify the ignoramus in the future.
My current desktop (2x256 GB stripped array) consistently tests above 900 MB/s read and write and yes, it does make a difference.
I also suggest you learn to read the entire post. If you had, you would have noticed that 800 MB/s is a useful performance increase, but is not in the speed range cited for the Mac Pro and that there could have been performance/battery life trade-offs involved.
its not... the 900MB/s that you get is basically a sequential IO speed, what some people like me actually interested is the random IO speed.
unless you move a lot of sequential data like 50GB of movies in and out from SSD like those RED owners, theres no way you would see any benefit from sequential IO increase.
large numbers 900MB/s sure impress everybody, thats what SSD manufacturers want everybody to think.
