"Intel's SSD 910: Finally a PCIe SSD from Intel"
 4/12/2012, AnandTech
  "... The first PCB features either two or four SAS SSD controllers, jointly
   developed by Intel and Hitachi (the same controllers are used in Hitachi's
   Ultrastar SSD400M). These controllers are very similar to Intel's
   X25-M/G2/310/320 controller family but with a couple of changes.
   The client controller features a single CPU core, while the Intel/Hitachi
   controller features two cores (one managing the NAND side of the drive
   while the other managing the SAS interface). Both are 10-channel designs,
   although the 910's implementation features 14 NAND packages per controller."
   "In front of the four controllers is an LSI 2008 SAS to PCIe bridge. There's
   no support for hardware RAID, each controller presents itself to the OS
   as a single drive with a 200GiB (186GB) capacity. ..."

  "MySQL is the persistent storage technology behind most Twitter data:
   the interest graph, timelines, user data and the Tweets themselves.
   Due to our scale, we push MySQL a lot further than most companies.
   ... we have decided to open source our MySQL work on GitHub under
   the BSD New license. ... Some of the work we’ve done includes:"

*)Add additional status variables, particularly from the internals of InnoDB
*)Optimize memory allocation on large NUMA systems
*)Reduce unnecessary work through improved server-side statement
  timeout support
*)Export and restore InnoDB buffer pool in using a safe and lightweight method
*)Optimize MySQL for SSD-based machines, including page-flushing behavior
  and reduction in writes to disk to improve lifespan
