@Tonny "I left that place after 3 months and I swore NEVER to do that again" sounds like cargo-cult employer selection to me :)

comment Why is this SSD drive failing with bad sectors, and was it predictable?
No sorry, there was no conclusive information about the reasons for failure, the manufacturer said to return the drive so I did. The system is built and currently has a few deployments in Zambia.

comment Why is this SSD drive failing with bad sectors, and was it predictable?
Thanks Brian, I'm accepting this answer as I have no better ones. My experience with hard disks is that sectors can be reallocated and hence recovery is possible. You are right about the reasons for using SSDs. Dust proofing is a big issue for Zambia. The drives will not be written often, most of the content is static. Solid state electronics are less affected by heat and humidity than spinning rust. RAIDing hard disks had occurred to us, but we were hoping SSDs would be more reliable and thus save money. Perhaps we were wrong. And schools have very poor connectivity so glusterfs is out.

comment Why is this SSD drive failing with bad sectors, and was it predictable?
I have not yet tried another controller/cable, because some sectors read fine repeatably and others error repeatably. I'm deducing from this that the fault is in the drive, not with the controller or the cable.
