Capacity Notes
Usable capacity after formatting is slightly less than the labeled capacity, which is normal for all flash storage products:
- 128MB = approx. 110–115 MB usable
- 256MB = approx. 220–230 MB usable
- 512MB = approx. 460–480 MB usable
This difference is due to how manufacturers and operating systems calculate storage. Manufacturers define 1 GB = 1,000,000,000 bytes, while your PC defines 1 GB = 1,073,741,824 bytes. This is standard across the industry and does not indicate a defective card.
Tip: For accurate speed testing, always use a high-quality card reader. Using a low-quality or incompatible reader will artificially reduce measured speeds and does not reflect the card's true performance.
