Warning: Partition 1 does not end on cylinder boundary.

I'm not sure why I get that warning, or if it should worry me... I
suppose I can always extend it a bit bigger if there is any problem with
this?
Because that fdisk is old and it's still thinking in the era of cylinder head sector; but that doesn't matter anymore. Everything is access by LBA these days.

it is topping out at 213M/sec…
For reference, I have a 2011 Macbook Pro (Core i7 2820QM) with SATA Rev 3.0, and a Samsung 830 SSD (the baby brother to the 840 Pros you have) and I consistently get 463 MB/s reads and 417 MB/s writes (with Bonnie++). That's one SSD, not RAID or anything. And it's a laptop.
Just a reminder, these are the Intel 320 series 480G SSD's.
Hmm, I guess I'm confused.
