• Memory like storage means file systems must change (nextplatform.com):

  Eric Barton of Lustre (formerly of Meiko Scientific) says filesystems must basically disappear due to #3D-XPoint memory #hardware or even the NVM-Express protocol for flash, despite the remaining need for wear leveling and write coalescing: “No longer do you have this big latency that lets you hide all of the functionality of the storage system. If you have this thickness of software between the application and the storage media, you deny the application the benefit of that media.” I think XPoint supports per-word erase rather than requiring flash’s per-page erase, which imposes so much complexity on the FTL.
