This is not an unusual move, given the popularity of the Pure flash based Storage and the Industry predictions of growth in Flash based storage. Synology FlashStations have been available for a very long time - with Specific RAID system for Flash, Synology NAS like other popular NAS are unpopulated and the System Integrator or end users, use storage from other vendors like WD, Seagate, Kingston, Samsung or Micron to populate the NAS. It changes with Synology branded SSD, since you can have a fully populated Pure-Flash NAS from Synology now.
