RAID 2 and 3 are rarely used strate

RAID 2 and 3 are rarely used strategies that are similar enough to
RAID 5 that we explain the general concept there. However, it should
be noted that RAID 3 gives particularly good performance for sequential
reads. Therefore, large graphics files, streaming media, and video applications
often use RAID 3. If your organization is hosting such files, you
may wish to consider a RAID 3 implementation for that particular storage
server, especially if files tend to be archived and are not changed
frequently.
