I can attest to their resiliency with data corruption.  I am using a
MD-RAID + LVM2 + LUKS/dm-crypt configuration.  I had a bad experience
over the last few months due to faulty Crucial Ballistx 1066MHz DDR2
memory.  After several dozen hangs, crashes, etc., several of my file
systems were corrupted.  After replacing the memory with Kingston EEC
modules I was able to boot an Ubuntu LiveCD and mount the RAID array,
LVM, and dm-crypt volumes and run fsck on the ext3 filesystem.  There
were errors all over the place but I was able to get my non-critical
but annoying to replace configuration files out of /etc and elsewhere.
