"Phase Change Memory-Based "Moneta" System Points to the Future of
 Computer Storage"
 June 2, 2011
  http://ucsdnews.ucsd.edu/newsrel/science/06-02-11data_frontier.asp

  "A University of California, San Diego faculty-student team is
   about to demonstrate a first-of-its kind, phase-change memory
   solid state storage device that provides performance thousands
   of times faster than a conventional hard drive and up to seven
   times faster than current state-of-the-art solid-state drives
   (SSDs)."

.....
  "Moneta uses Micron Technology's first-generation PCM chips and
   can read large sections of data at a maximum rate of 1.1
   gigabytes per second and write data at up to 371 megabytes per
   second. For smaller accesses (e.g., 512 B), Moneta can read at
   327 megabytes per second and write at 91 megabytes per second ,
   or between two and seven times faster than a state-of-the-art,
   flash-based SSD. Moneta also provides lower latency for each
   operation and should reduce energy requirements for
   data-intensive applications."

Moneta and Onyx: Very Fast SSDs
  http://nvsl.ucsd.edu/moneta/
"Onyx, our second storage array prototype, is one of the world's
 first PCM-based SSDs."
.....
"Even though it uses first-generation phase-change memory devices,
 it can still sustain over 1.1GB/s for reads. Writes are a good bit
 slower, but our plan is to upgrade Onyx soon to use newer, denser,
 faster PCM devices."

  "Steven Swanson, professor of Computer Science and Engineering and
   director of the Non-Volatile Systems Lab (NVSL) at UCSD, foresees
   commercial products within a few years; so we are looking beyond
   2014 before actual PCM devices appear. He says work will need to
   be done on the software front to fully realise the benefits of
   the PCM hardware."
