2-13-5 RAID-3 Storage Volume—Disk Striping with Parity
This RAID-3 feature is unique to the easyRAID family of NAS and is the first to be
available in this type of product. While RAID-3 is similar to RAID-5, this feature is
different in that it does not have a stripe size option. RAID-3 is most efficient for small
number of users who are working with large files. When multiple users require access
to the NAS and smaller file sizes, it is more efficient to utilize a RAID-5 system.
Figure 2-15 shows the screen when RAID-3 Option is used.
