The main point of "enterprise" flash SSD models is (as the
original poster wrote) the ability to enable write-back (thus
much, much higher committed write rates), if they have

I read the OP as they meant enabling the write-back mode of LVM cache, where
loss of the SSD may lead to a data loss for the entire array, and justifying
that simply by the SSD being a reliable datacenter one. My objection was to
that, but perhaps indeed I understood that part wrong.
