He has redundancy.

A more likely cause of the problem is a possible lack of ECC memory 
(data in memory was read incorrectly), disks which don't honor the 
cache sync request (a drive firmware issue), or some common element 
(drive firmware bug, flakey power supply, shared cable) which causes 
both drives to have a problem with the same written data.

The comment about a "developmental OS" was not helpful since any 
system could lose data.
