No problem with that, for a first step. ***BUT*** the failures in this article 
and
many others I've read about are not in high-write db workloads, so they're not 
write wear,
they're just crappy electronics failing.

As a (lapsed) electronics design engineer, I'm suspicious of the notion that
a subassembly consisting of solid state devices surface-mounted on FR4 
substrate will fail
except in very rare (and of great interest to the manufacturer) circumstances.
And especially suspicious that one product category (SSD) happens to have a much
higher failure rate than all others.

Consider that an SSD is much simpler (just considering the electronics) than a 
traditional
disk drive, and subject to less vibration and heat.
Therefore one should see disk drives failing at the same (or higher rate).
Even if the owner is highly statically charged, you'd expect the to destroy all 
categories
of electronics at roughly the same rate (rather than just SSDs).

So if someone says that SSDs have "failed", I'll assume that they suffered from 
Flash cell
wear-out unless there is compelling proof to the contrary.
