I totally agree with this...

As I understood he has:
+--------+--------+--------+--------+
| Disk 1 | Disk 2 | Disk 3 | Disk 4 |
+--------+--------+--------+--------+
| RAID 0          | RAID 0          | <- Via P420i RAID controller
+-----------------+-----------------+
|               RAID 1              | <- Via MD RAID
+-----------------------------------+
| Whatever Partition, LVM, FS etc.  |
+-----------------------------------+

Is this correct Asif?

If it's correct, one (or two - it depends) disk can fail without a data 
loss.

Just buy more cache and build it from scratch.
