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)
