Since there are already 1 TB SSDs on the market, the only thing keeping the
HDD market alive is the low $/TB. Moore's Law predicts that cost advantage
will pass. SSDs are already the low $/IOPS winners.
SSD vendors are still working to stabilize their designs. Most of
them seem to be unworthy for use in more than a laptop computer. A
number of computer vendors (e.g. Apple & Dell) who offered SSDs in
their computers encountered an expectedly high rate of product
failure.
According to Sun's own engineers, Moore's Law is very bad for
enterprise SSDs. FLASH devices built to very small geometries are
more likely to wear out and forget. Current design trends are moving
in a direction which is contrary to the requirements of enterprise
SSDs. See

Perhaps inovative designers like Suncast will figure out how to build
reliable SSDs based on parts which are more likely to wear out and
forget.
