Advancements in NAND flash memory technology, particularly the development of 3D NAND which allows for vertical stacking of memory cells, have significantly increased the capacity of USB flash drives. This evolution has enabled drives to reach capacities such as 512GB without increasing their physical footprint.

As storage density has increased, low-capacity models like 1GB drives have become economically unviable for the consumer market. Although the cost per gigabyte has dropped drastically over time, the manufacturing costs for essential components—including controllers, circuit boards, casings, and connectors—remain relatively constant regardless of the memory chip size. Consequently, producing small-capacity drives is no longer commercially competitive.

Modern software requirements have further contributed to the decline of low-capacity drives, as certain installation tools now require minimum capacities such as 8GB. While consumer-grade low-capacity drives are becoming rare, specialized industrial and embedded sectors continue to utilize smaller capacities for specific compatibility and durability needs.

Technological distinctions have also emerged between physical connectors and communication standards. While USB-C describes the physical shape of the connector, standards like USB4 govern data transfer speeds, which can reach up to 40 Gbps and support simultaneous charging and high-resolution video output.
