NVMe is built for SSDs
SSD technology grew enormously alongside advances in CPU and
GPU. With a signicant boost in storage capacity and performance,
NAND Flash - the technology behind Solid State Drives - possesses the
capability to do far more. The Non-Volatile Memory Express (NVMe)
protocol was specially created for NAND Flash storage solutions to
accelerate transfer speeds by overcoming legacy constraints in existing
storage interfaces and protocols. SATA was optimized for mechanical
Hard Disk Drive Storage, but even with revisions over time, the current
SATA 3 interface bandwidth does not accommodate the full potential
of NAND Flash based SSDs.
When it comes to a PC’s system “responsiveness”, storage is one of the most crucial hardware components. The faster the drive, the faster the
system boots, the faster apps launch, and the faster les save. The introduction of SSDs a number of years ago was a major step forward from
traditional spinning HDDs, but SSDs recently hit a performance wall in the existing SATA III protocol, and they simply cannot run any faster.
Overview
Introduction to Samsung NVMe SSDs
Transfer faster with NVMe SSDs
Non-Volatile Memory Express (NVMe) protocol was especially designed
for NAND Flash storage solutions to unleash a new dimension of data
transfer speed. It allows SSDs to achieve peak performance, 6-7 times
the sequential read/write speeds of SATA.

More gains from NVMe SSDs
With the faster data transfer speeds of the PCIe interface and the
NVMe protocol, the SSD of the future is scalable with a theoretical
transfer speed of up to 31,504 MB/s (using PCIe 4.0).
NVMe SSDs unlock a new level in speed, capacity, and form.
Besides providing a leap in performance, NVMe SSDs are smaller, lighter,
more efcient, and easier to install (no cables). The M.2 form-factor
reduces the overall size of internal storage devices. Standard M.2 cards
are just 22 mm wide, allowing dramatically expanded capacity without
messy cables, power wires, or bulky disk housing.
