1. Affordable price and reliable memory stick. Our 4-piece USB flash drive is available at a competitive price on the market. 2. Compatible and compact USB 2.0 flash memory sticks are compatible with operating systems such as Windows 2000/7/8/8.1/10/Vista/XP/2000/ME/NT Linux and compatible with USB 2.0 and lower versions. 3. Capacity difference between factory capacity and computer capacity. For the factory capacity of 32 GB, the calculation is as follows: 1 MB = 1000 KB, 1 GB = 1000 MB. 4. Warm reminder. The standard 16g storage format is NTFS/exFAT. If using the format on a memory card (including cameras), you will need to transfer the format. The read/write speed depends not only on the USB storage device itself but also on the computer environment such as the system and files. For example, the reading speed of a 48MB file is faster than that of a 48GB file.
