Will NAND make HDDs Obsolete?

NAND (short for "Not AND") is a type of non-volatile storage technology that is commonly used in solid-state drives (SSDs), memory cards, and USB flash drives. It has several advantages over traditional hard disk drives (HDDs) – lesser physical space (which enables larger storage), faster read and write speeds, lower power consumption, and better durability. These factors eventually lead to lowering the total cost of ownership (TCO).?
In addition, NAND has lower latency. As the drive gets bigger and bigger, data gets bigger and bigger. We need a technology that drives the lowest amount of latency into the system, and NAND fits in neatly with this requirement.
These benefits often make us think that NAND-based Flash storage has the potential to completely replace hard drives.?
While NAND has made significant inroads in the storage market, there are several limitations:??

As NAND technology is constantly improving, it is possible that it could eventually replace hard drives in some applications. For example, NAND-based SSDs are already being used in servers and enterprise environments, as well as primary storage devices in laptops and desktop computers.?
However, it is unlikely that NAND will completely replace hard drives in the near future, as the lower cost and higher storage density of HDDs make them a better option in many situations.?
