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."

There's going to be a revolution. Addresses on disk will be byte granularity and indicated by 64-bit values. It will probably still be blocks, but addresses will be bytes. It could mean entirely different operating system.

See https://en.wikipedia.org/wiki/IBM_System/38#Data_Storage and and https://en.wikipedia.org/wiki/Object_storage_device (To me, OSD always looked a bit like ZFS' lower storage layer - and I think there's even a certain overlap in people working on ZFS and the OSD standard)
