Two decades ago, 1GB of flash memory was considered serious, high-cost storage. In early 2002, the industry was excited about JMTek's USBDrive and its capacity of up to 1GB. Today, that same capacity is trivial by consumer standards. Most current Kingston DataTraveler models start at 64GB, with some reaching 512GB.
Storage became drastically cheaper along the way, and the price collapse was equally dramatic. USB storage went from more than $8,000 per gigabyte in its early years to 94 cents per gigabyte by 2013. The basic recipe did not change much, as a USB flash drive still needs a USB connector, controller, circuit board, casing and one or more memory chips. A 1GB unit did not become impossible to manufacture. It became rather unprofitable to sell.
The real change happened inside those memory chips. For decades, NAND manufacturers have found ways to make memory cells smaller, fit multiple bits into each one, and even stack those cells vertically with 3D NAND. This allows them to pack far more into a USB flash drive without making the device so large you would need a backpack to carry it.
A notable example occurred in 2005, when Toshiba and SanDisk announced an 8Gb (gigabit) NAND chip capable of storing 1GB in a single chip. It was less than 5 per cent larger than the previous 4Gb generation from both companies, but offered double the capacity. In the announcement, the companies said it would become the "workhorse of production... bringing significant cost reductions" to their flash storage products.
The numbers scaled quickly, with the Verbatim Store 'n Go of 2.1GB priced at $250 in 2004. By 2013, Kingston had released a 1TB DataTraveler, while the already available 512GB version cost a rather steep $1,750. TLC NAND compresses three bits into each memory cell and is commonly used in price-sensitive consumer storage, such as USB flash drives. Capacity and speed have increased, but bigger does not automatically mean faster. NAND matters, as do the controller and USB interface.
Reducing a 64GB unit to 1GB does not magically eliminate the rest of the hardware. After all, the low-capacity version still needs a controller, connector, circuit board, casing and packaging. It still has to be assembled, shipped and placed on a store shelf. Once high-density NAND becomes cheap enough at scale, reducing storage capacity does not necessarily reduce the cost of the finished product significantly.
There is no clear capacity at which the economics stop working, so there was no magic day when manufacturers en masse decided that 8GB had displaced 1GB, but the industry shifted over time. Microsoft's Windows installation media tool requires a blank USB flash drive with at least 8GB of space, making a 1GB unit too small for one of the most ordinary jobs you could assign to a spare USB flash drive.
MLC NAND (multilevel cell) is also being squeezed on the production side. Global MLC NAND capacity is expected to drop 41.7 per cent year-on-year in 2026 as major suppliers reduce or halt production and channel more resources toward newer processes. This may create the slightly unusual result of an older NAND type becoming more expensive as supply declines.
Small units have not disappeared entirely. Some survive in industrial and embedded applications where compatibility, durability or a fixed hardware configuration may be more important than accumulating capacity. Delkin sells industrial USB flash drives starting at 1GB, while Apacer goes lower, with industrial USB flash drives starting at 256MB.
