Well, yeah: those of us with mis-sized disks, without infinite money, and 
with a desire to at some point add a few extra disks without replacing the 
lot tend to prefer md :)

(also, md has the best support on Earth. I defy you to find a nicer or 
more responsive or capable maintainer for *anything* than Neil Brown.)

Software vs. Hardware RAID-1

Another reason to prefer software RAID-1 is that I don't need to keep a spare instance of the hardware RAID controller around to cater for the case where the controller dies. I can simply put the disks on any controller I happen to have around.

Finally, from what I read, Linux software RAID-1 is just as fast as hardware RAID-1, so the only advantage of hardware RAID-1 seems to be that GRUB works better with it.

Hardware RAID uses less bus bandwidth than software RAID does, of course, 
so if your bus is really busy you might need to go hardware RAID or accept 
a slowdown.
