Intel has been redesigning their 3D Xpoint memory product to be able to install it in corporate servers with DDR4 sockets. The new design is almost as fast as DRAM and it is persistent like SSD and hard disks.
This move will change the paradigm of the PC for consumers as eventually this technology will be widely available. The persistent memory is presented as storage with a very fine granularity of 64 bytes which is the same as DDR4 memory.
For a conventional PC, we see the new memory has being perfect for the swap file which presently is stored on the SSD/hard disk. Now a faster persistent memory would be ideal for the swap file and the hibernate files which would make reboots dramatically faster.
Intel mentioned that 2 sticks could reach 6TB of storage which is more than a laptop needs with Windows 10 and perhaps Microsoft Office installed..
If Intel can reduce the cost to below SSD prices, it may be able to completely replace them in the marketplace. It maybe sometime before Intel can mass product the 3DXP memory in adequate amounts for laptops.
It may be some time for Intel to refine the technology so that consumers can use it like SSD drives which have a controller to manage the cells and handle problems transparently. At present Intel is offering a SDK for developers to use the raw storage in a tiered storage model.
Once 3DXP has matured we expect it to be available to consumers perhaps in a PCI Express card or M.2 card. SSD drives have gobbled up the SATA market making it almost universal in laptops.
While Intel flogs the product to corporations, gaming needs are simpler., Only need 2 kinds of storage, volatile like DDR4 and persistent like SSD and hard disks. 3DXP is simply now faster persistent storage.
Intel believes it can be make 3DXP in larger capacities which will be helpful for large game libraries.
