Yes, I believe this. RAID is risky whether closed or open, there are a
lot of not so well done implementations. With hardware RAID the thing
to worry about is, does it eventually write its caches out to disk.
Yes, there are some that do not, and then the battery fails and 6 month
old data goes poof, resulting in a support call in which we tell a
sysadmin the sad story of how fsck does not work if there is nothing on
disk, and no it is not reiserfs it is the hardware RAID that made it go
poof, and then they go back to the large established vendor and sure
enough do confirm that it is a known bug....
