Yes, that's true, though, I am a bit confused because the Clariion array document I am reading talks about how the write cache can eliminate the

well, then run your own tests and find out :-)

if I were using LSI MegaRAID controllers, I'd probalby go RAID10, but I don't see why you need 6 disks for this... perhaps just 4 would be enough? Or are your logs really that big?
