For longer tours, higher capacity cards will be needed.ġ. If you want to take 300 photos, at least 1GB capacity is required. Generally speaking, a high pixel photo is 2-3MB. What capacity of card is considered to be enough for a digital camera taken on a trip?Ī: This depends on your need. It is a common benchmark used to measure performance of storage devices. Higher IOPS means the device can more quickly read and write the many small files used by these programs, resulting in more speed and better natural support.Ī: IOPS stands for Inputs/Outputs Per Second. Why does higher IOPS mean better support for Smartphones and tablets?Ī: Currently the general public uses Smartphones and Tablets with many small software applications and game-based programs. When the test is finished, open the recently saved file results.csv (By Office) Select GA Memory perf test Random Read First.icf How do I confirm that the IOPS comply with the specifications marked on the product?Ĭlick the icon to Open Test Configuration Fileġ. So be sure to confirm whether the card reader supports UHS-I.

The read and write speed differences for a card reader with or without UHS-I support are significant (see below). How do I confirm using a UHS-I supported card reader that it is operating at the speed it should have?Ī: This can be tested using the HDBEHCH program. Which ADATA memory cards are best for use with my dashcam?Ī: We suggest ADATA’s Premier or Premier Pro series microSDHC or SDHC cards. ** The detailed preconditions and test are defined in SD 6.0 Part 1 Physical specification. * The detailed preconditions and test are defined in SD 5.1 Part 1 Physical specification. What’s the difference between A1 and A2 standards?Ī: Please find the table below for detailed information. The fastest way to calculate: The capacity labeled on the product x 0.93is about equal to the actual capacity recognized in the computer. But, the computing unit of the computer calculation is a binary system, so the 128GB calculated by the storage device is converted into bytes, 128,000,000,000Bytes, so what will be displayed through computer’s calculation method is 128,000,000,000/1024/1024/1024≒119GB. The storage device is usually calculated in the decimal system, while the computer operating system is calculated on the basis of the binary system. Why is the available actual capacity of Memory Cards device less than the amount indicated on the package?Ī: The differences in the display of capacity are the results due to the calculation of the computer operating system differs from the way of the storage device through the Controller IC.
