PNY High Performance - Flash memory card (microSDXC to SD adapter included) - 64 GB - UHS-I U1 / Class10 - microSDXC UHS-I

Specifies the physical configuration or design of a product, such as ATX, Micro‑ATX, Mini‑ITX, tower, case with cover, etc. It describes how the device is built and what mounting or expansion options it supports.

The range of relative humidity (expressed as a percentage) within which the product is designed to operate reliably. Values are given as a minimum–maximum interval such as "10 to 80%" and indicate the acceptable environmental moisture level for optimal performance.

The specific type of adapter that allows a memory card to be used in another format, such as microSDHC to SD or microSDXC to SD. It indicates the physical connector and conversion function required for compatibility.

The highest rate at which a storage device can retrieve data, expressed in bits per second (bps) or common units such as MB/s or GB/s. This value represents the theoretical upper limit of read performance under optimal conditions and is useful for comparing devices that use similar interfaces.

The SD Speed Class indicates the minimum write speed that a Secure Digital (SD) memory card guarantees, expressed as a class number such as 1, 2, or 10. It helps consumers compare cards for performance in devices like cameras and smartphones.

The total amount of data that can be stored on the device, expressed as a numeric value with an appropriate unit such as GB, MB, or TB. This attribute helps users understand how much information the product can hold and compare storage options across different devices.

The maximum speed at which a device can write data to storage or memory, expressed in bits per second (bps) or common units such as MB/s or GB/s. This value indicates how quickly the device can transfer information during write operations and is useful for comparing performance across models.
