Ho hum, that does not really say much. Are you going to use raid5 with
30 disks with spares? raid6? I am also planning to cut costs by using a
200USD or so hba or two and software raid to manage the lot versus
getting something five times more expensive with just 512MB of bbu
cache. I mean, if I am going to use raid10, why bother with a raid
controller when the performance differences will be rather slight? If it
were raid5/6 that will be used, then yeah, give me a raid controller
with lots of cache.

Interesting. hard links and rsync eh? Do you think it can manage
rotations of 2000 for data over 500GB in size?
