We've had 3 SSD failures out of 5 SSDs, and 0 magnetic failures out of 8 magnetic drives in our office over the last 2 years. We definitely keep only OS, programs, and VMs on SSDs.

Your sample size is too small, and your data isn't independent. Both magnetic disks and ssds fail, multiple backups are the only way to protect data.

I've had 3 failures out of 8 HDDs and 0 out of 2 SSDs (Intel X25M and Samsung 830) in the same period.

At this point I would recommend buying SSDs that have proven track records; don't buy cheapest on the basis that any SSD is better than any HDD.

We bought all of them on reliability track record alone.
