The only ways I know of to currently detect/repair silent data
corruption are via the use of T10-DIF on SAS drives with 520-byte
sectors and embedded per block CRCs (bytes 513-520) or via a patented
algorithm used in a commercial Linux software RAID product
(www.streamscale.com).
Neither approach is cost effective for small or personal use RAID
applications.

well i think the integrity is know, but it´s not fully needed since
the security isn´t a problem we can buy secure sata/sas
controlers/disks
the main problem will be in some days when we are using SoC systems
and we only have USB to connect a harddrive... maybe when this become
more popular we will see a development of a module to have data
integrity (silient corruption detection and maybe repair)
