6. For redundant RAID arrays (RAID 1, 5, 10), select the Cache Policy:
Write Back – Provides higher write performance for redundant RAID arrays. Data is at risk when there
is a power failure, system kernel panic and un-responding abnormal conditions.
Write Through – Writes directly to the disks (may reduce the risk of data loss during a critical failure,
but at the cost of lower performance).
7. Sector Size – Also known as "Variable Sector Size". Use this option if you are using an older 32-bit
Windows operating system. This allows older operating systems to support volumes over 2TB in
size. Do not use if the operating system already supports large volumes (such as GPT).
8. Block Size –64K block stripe size is a good choice of many applications. Other HighPoint RocketRAID
controller 3000/4000 series have adjusted RAID block to fit applications needs.
9. To complete the creation procedure, use the arrow key to highlight the Start Creation item and
press Enter key.
The Window will show 4 options if create RAID 5: Foreground Initialize, Background Initialize, Quick
Initialize and Keep Old Data.
