Conclusion and Final Thoughts
 The DDRdrive was purpose built for pure unadulterated random IO, and from what I have seen, it absolutely delivers.  The only thing holding it back from decimating the competition is the single channel PCI-E bandwidth.  Enterprise environments requiring hugely random yet persistent storage (i.e. database transaction logs), may benefit from the X1, provided the storage space is sufficient and their IOPS requirements fall within the X1’s respective sweet spots.

DDRdrive hits the ground running - PCI-E RAM-based SSD - Storage 23

  • Single sector IOPS unmatched by any other device available
  • Integrated backup to / restore from SLC flash memory
  • Cost vs. IOPS (nearly 1/5th the cost of an ioDrive)
  • IOPS / Watt
  • Extremely well engineered part
  • Limited capacity of 4GB
  • Cost / GB
  • Limited bandwidth
  • Not bootable (yet)
While the DDRdrive is not yet bootable, it is worth pointing out that neither is the ioDrive.  Both companies have it on the drawing board.

The DDRdrive X1 is shipping as of today for a cost of $1495.
