Early products are certainly faster and more durable than NAND and denser than conventional memory, but they haven't yet quite lived up to the full extent of these claims. For industrial applications where cost and reliability are of equal importance, this offers a good middle ground.
The comparison table below highlights the differences of the main types of NAND Flash and their key characteristics. But is it truly ideal for industrial applications? The answer is that it really depends on what it is being used for. SLC and MLC will not disappear overnight, in fact, supply and demand are still strong for both given their unique performance characteristics and customisation attributes.
There is certainly no immediate need to switch to 3D NAND as the technology is still relatively new to the industrial market and will evolve over the next few years as specialist industrial manufacturers, such as Innodisk and ATP Electronics, push the boundaries of this technology.
It is certainly worth considering alongside SLC and MLC products but sits at the lower end of the pricing, endurance and performance spectrum.

NAND flash memory is a type of non-volatile storage technology that does not require power in order to retain data.
It uses floating-gate transistors that are connected in a way that the resulting connection resembles a NANA gate, where several transistors are series connected and a bit line is pulled low only when all word lines are at a high state, hence the name.
The technology is used in common storage devices such as flash drives, solid-state drives and memory cards. NAND flash memory is a type of flash memory that stores data in arrays of memory cells that were made using floating-gate transistors. It contains two gates, namely, the control gate and the floating gate, and in order to program a single cell, a voltage charge must be applied to the control gate.
Electrons are then attracted toward the control gate, but the flow gate traps them within the substrate where they can remain for years under normal operating conditions. In order to erase a cell, the control gate must be grounded and a voltage is applied to the opposite or to the substrate.
NAND flash memory is the most common type of memory being used in the mass market because of its affordability, storage density and access speeds. Admission Essay.
