Is the capacity real?

Yes. All USB flash drives supplied by JINKEUDSK are 100% genuine capacity products with no fake or artificially expanded storage. We implement strict quality control procedures to ensure every unit fully complies with its labeled specification.

• Original brand chips

JINKEUDSK uses authentic flash memory chips sourced from reputable global manufacturers including Hynix, Micron, Toshiba, and SanDisk. No recycled chips, substandard materials, or unauthorized components are used in production, ensuring stable performance and reliable data integrity.

• Full capacity testing before shipment

Each USB flash drive undergoes individual capacity verification prior to delivery. This process ensures that the actual usable storage matches the labeled capacity. A slight difference between labeled and usable capacity is normal due to system formatting and file structure requirements, such as a 32GB drive showing approximately 29 to 30GB of usable space.

• Verifiable through standard testing tools

Customers can independently confirm real capacity using widely recognized tools such as H2testw or ChipGenius on Windows systems, or by performing complete data write and read verification tests. All products are designed to pass legitimate and transparent testing methods.

• Quality warranty assurance

All USB flash drives are covered by a 12-month quality warranty. If any product fails a genuine capacity verification test, a replacement will be provided at no additional cost.

JINKEUDSK guarantees full transparency in storage capacity. What is specified is exactly what is delivered, with no inflated figures and no hidden modifications. We strictly prohibit any software-based capacity manipulation or false labeling. Unlike unreliable suppliers that may artificially inflate storage values, JINKEUDSK ensures all products operate strictly within their true physical memory limits, preventing data loss or file corruption risks.
