I'm also trying to evaluate different strategies for RAID0 as drive
for cassandra data storage. If I need 2T space to keep node tables,
which drive configuration is better: 1T x 2drives or 500G x 4drives?
more drives is always better.
Which stripe size is optimal?
smaller stripe sizes are better for reads, larger for writes. optimal
stripe size depends on index sampling interval and average read size.
Should I use hardware raid or linux raid is ok?
expensive ($500) HW raid is way better (about 2.5x faster) if you can
get it. Linux raid is better then cheap hw raid. Also expensive RAID
cards are way easier to manage.
