Gets interesting in terms of recovery, boot times, app access times. Its

non-volatile in high GB/low TB range of memory based storage, so one 
could easily see a system disk loaded in memory and you would not need 
to use batteries etc. to back anything up (notwithstanding DR data)

To put things in perspective, a relative comparison of increasing
latency 
to size of stored data: 

SRAM - latency : 1x, size of data : 1x

DRAM - latency : 10x, size of data : 100x

3D XPoint - latency : 100x, size of data : 1,000x

NAND (SSD) - latency : 100,000x, size of data: 1,000x

Disk (HDD) - latency : 10 million, size of data: 10,000x

Hence, importance of getting data closer to the compute engine
Is becoming much easier ..
