BIOS - How to create RAID volume
Appendix
IND100077-190
Procedure to reset disk mode in Microsoft ® Windows ® 7 before capturing image:
- Open Registry Editor and go to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\
For each of the subkeys: Msahci, iaStorV and iaStor ;
- Find “Start” string, doubleclick and change value from 3 to 0, if not set.
- Exit and shutdown the unit.
System image should be saved before Windows is booted again.
Note: For best performance and stability, we recommend installing latest supported Intel Rapid Storage Technology (RST)
driver and software.
Available RAID levels:
- RAID 0 - Striping.
Requires 2+ drives.
Increased Read and Write performance.
No redundancy.
Not recommended for critical systems!
- RAID 1 - Mirroring.
Requires 2 drives.
Increased Read performance.
Good redundancy.
Recommended for most setups.
- RAID 5 - Block-level striping, with distributed parity.
Requires 3+ drives.
Increased Read and decreased Write performance.
Decent redundancy, only one drive can fail.
RAID5 is generally not recommended. It should be avoided for large drives (1TB+) due to slow rebuild time
and increased risk of second drive failure.
- RAID 10 - Mirrored and striped. Not available (requires 4 drives, only max 3 drives possible on HT B30 models).
- Recovery - Backup data to recovery disk.
Requires 2 drives.
This is not RAID but a backup function to copy data from master disk to a recovery disk.
Master and Recovery disk needs to be set in Select Disks option.
Available syncronisation options:
Continuous - Updated automatically.
On Request - Updated manually.
