Memory card Silicon Power microSDHC Superior USH-1 (U3) (32 GB): review and testing

Every year we are seeing a gradual increase in the quality of multimedia content. More recently, a video in Full HD was a standard, but the resolution of cameras was within 8 megapixel. Now popular are 4K Ultra HD and 20-megapixel sensors in smartphones. It is logical that with the increasing quality, requirements are growing to the volume and speed of the memory card. To satisfy these requirements, a solution High-Speed Class 3 (UHS-I (U3)) was developed, which provides a minimum write speed of 30 MB/s.

File system

By default, the memory card is formatted in system FAT32, which is characterized by restrictions on the maximum size of the file (4GB). Moreover, its effective capacity is 29.8 GB. Lack of space to the declared capacity is due to the decimal unit conversion, which is a common marketing ploy of all manufacturers.

After formatting the memory card into the file system NTFS, 90.6 MB is reserved for its needs, and the available space gets even smaller. However, in connection with the above restriction in the file system FAT32, it is more logical to use the device of 32 GB for NTFS or exFAT, which are devoid of such shortcomings.
