If I understand correctly, you're attempting to simply add additional
drives to your existing non-RAID boot partition, instead of creating a RAID
setup on additional not yet formatted partitions, no?

Is this vastly read-only or will write speed also be a factor?

Please excuse a clueless newbie question here,
but if you've got a journaling filesystem, wouldn't you want to expose the
raw disks to it so it can choose to put the journals on different disks
than the files?
This would not only help with performance, but it would also make recovery
as simple a

You signed up 60,000 customers between your nightly backup and the failure
point? I want to know where you advertise!
Seriously, RAID is NOT the same as ha
Oh good grief!
The Hyperdisk controller has a FIFO too. That's gotta accelerate RAID-1
performace by a few tenths of a percent on certain benchmarks.
It's not like the product's only value add is that BIOS chip and the
bundled software RAID.

Bug1: Maybe im missing something here, why arent reads just as fast as writes?
The cynic in me suggests that the RAID driver has to wait for the
information to be read off the disks, but it doesn't have to wait for the
writes to complete before returning, but I haven't read the code.

Does anybody really want to wait while their swap data is duplicated out to
multiple disks by a CPU that is working to free up memory to run
applications?
Isn't Swapping slow enough already?
Why not simply swap on multiple disks, get Hardware RAID-5 for swap or buy
RAM?
