The lifecycle of 3D XPoint is 1,000X
Tzubair, NAND Flash memory at one time was known to be able to support 5,000 reliable writes and rewrites. 3D XPoint supposedly has 1,000 times the endurance of Flash, according to joint Micron/Intel information.

Atom based storage
"the size of the memory cells can continue to shrink on the chips, in part, because it is "not a charge-based data storage approach. We are actually changing the atoms in the memory cell" as the basis for data retention without charge"

I think that presents with a very unique approach towards storage. Eliminating the "charge-based data storage approach" and using atoms instead will not only save a lot of space it should make it possible to also have storage that works without power and can be read and written without the need for an electronic connection.

Re: Fix the security issue, XPoint, then I'll be impressed
"I have a problem with the caching of the data in memory even after powering down. This is an inherent security risk I would rather not have to deal with"

@asksqn: I don't think that's a big risk. You have tons of data in the disk drive which is encrypted for security. Only a fraction resides in the memory that gets cleared upon power down. As long as there's proper encryption, I don't think there's a big security lapse involved here.

Re: .3D XPoint: not the same as what's gone before
" It can also be written to and rewritten to many more times than solid state components can."

@Charlie: Any idea about its life in terms of the time duration for which it can be used for on avearage? Apart from the use, the time itself should also matter so that the ufront cost can be aportioned accordingly.

Fix the security issue, XPoint, then I'll be impressed
While speed is nice, I have a problem with the caching of the data in memory even after powering down. This is an inherent security risk I would rather not have to deal with.  In fact, I predict security researchers to point out this glaring security hole and XPoint, like all tech manufacturers, attempt to silence that research using the standard bludgeoning tool - the DMCA- to silence any research it does not like.

.3D XPoint: not the same as what's gone before
3D XPoint is a new memory technology that, if it lives up to its p;romise, will make it easier to equip small devices with much greater memory capacity. It can also be written to and rewritten to many more times than solid state components can.
