I am looking for a way to make a raid 1 of two SSD's, and to be able to detect corrupted blocks, much like btrfs does that. I recall being told about a month ago to use a specific piece of software for that, but i forgot to make a note of it, and I can't find it anymore.

Running SSD's in RAID1 has been contentious from the perspective that I 
have been researching storage technology.

Is there any serious, properly researched, and learned infornmation 
available about this?

The reason I ask is that, in a related situation, I have 4x high quality 
HGST SLC SAS SSD's, and I was seriously thinking that RAID0 might be the 
appropriate way to configure them.  This assumes a well designed backup 
strategy of course.

Is this foolhardy?
