I just wanted to double check something before I return a failing SSD.

I set up a 2 partition raid 10 in far 2 mode... from what I understood
it allows a mirror and stripe to exist on a 2 drive set up, so that it
gets the benefits of stripe with the redundancy of mirror.
I should clarify, two partitions on two different SSD's not the same
SSD :-/   /sda4 and /sdb4
I just wanted to double check this was correct and if so confirm that I
can fail and remove one of the drives.

Obvioulsy I will have to drop one of the drives anyway/somehow but if it
wont hold up/keep running after failing one drive then I will have to
deal with it in another way, probably a quick clone onto a spare disk as
a stop gap measure until I get the replacement, as this array is my OS
disk.
