Possible reason : You may have used your USB drive or Memory card on a device that doesn’t support storages larger than 32GB or exFAT/NTFS format, or the device was automatically or manually formatted into 32GB or FAT32. Therefore the capacity only shows 32GB on your windows OS. How to recognize? Right click “This PC”-> “Manage”->”Disk Management” to check the partition of capacity. E.g. A 128GB USB flash drive only shows 32GB on WINDOWS. 116.13GB* online: Which means the drive is at normal 128GB capacity. * Part of the capacity of FLASH storage products will be used for formatting or other functions, therefore the displayed capacity in the operating system will be less than the actual storage capacity due to unit conversion. It is recommended to calculate the actual storage capacity based on this equation: total bytes/1024/1024/1024. Primary partition 32GB: Which means only 32GB was set. Unallocated capacity 84.12GB: Which means there is still 84.12GB unallocated. How to solve it? a. Right click to delete 32GB volume on “Disk Management” and reformat it. (Backing up your files is suggested.) b. Right click to create new volume and follow the default format and finish the format. c. Finish format. Check the capacity.
If you want to copy a single file larger than 4GB to SSD, Please format the SSD to NTFS format. (Path: My Computer>Right click on the SSD->Select the Format option on the function menu>Select the NTFS from the File System item>Press Start button).

SSD is an abbreviation for solid state disk. The conventional hard disk does not belong to "liquid" hard disk; solid state disk refers generally to solid state disk composed of NAND Flash. It has no mechanical structure and performs transfer via electronic signal compared to rotational disk design used in conventional hard disks. It utilizes characteristics of conventional NAND Flash and is composed of control unit and storage unit (FLASH chip). Data storage is achieved by the combination of the two units. Data is read and written in block writing and erasing manners. Thus, the efficiency of reading and writing relies on the design with respect to read-write technologies very much. It is advantageous of high speed, low power consumption, vibration resistance, high stability, low-temperature resistance etc.compared to current conventional hard disks.
