Hardware, Embedded Systems "In the past five years, flash memory has progressed from a promising accelerator, whose place in the data center was still uncertain, to an established enterprise component for storing performance-critical data. It's rise to prominence followed its proliferation in the consumer world and the volume economics that followed. With SSDs, flash arrived in a form optimized for compatibility - just replace a hard drive with an SSD for radically better performance. But the properties of the NAND flash memory used by SSDs differ significantly from those of the magnetic media in the hard drives they often displace. While SSDs have become more pervasive in a variety of uses, the industry has only just started to design storage systems that embrace the nuances of flash memory. As it escapes the confines of compatibility, significant improvements in performance, reliability, and cost are possible."

... Let alone the implications of having a complex firmware that handles garbage collection behind the OS' back.

In 40 years, we have learned all-there-is-to-know about magnetic drives - especially, how they fail.
We have yet to reach the same level of maturity when it comes to SSD's. (Let alone the fact the possibility of bricking all the members of the storage pool, all at once, due to a firmware bug).

SSD will replace HDDs - there's no doubt about it.
However, I tend to choose caution over innovation when it comes to data storage...
