About Hardware SanDisk Ultra MicroSDHC 8GB

The SanDisk Ultra MicroSDHC 8GB is an 8GB memory card that supports Class 10 UHS-I speeds, designed for everyday storage purposes such as storing photos, videos, or light files on mobile devices such as smartphones, digital cameras, or tablets. Although the capacity is relatively small by today's standards, this card is still useful for basic purposes or as backup media.

With a read speed of up to 80MB/s theoretically, this microSD card is enough to support HD video playback and light data transfer. However, the limited capacity makes it less suitable for storing large amounts of apps or multimedia files.

The test was conducted using a Lenovo IdeaPad Slim 3i 14ITL6 equipped with 12GB DDR4 Dual Channel RAM and Windows 11 22H2 operating system. The card was tested through a VENTION USB 3.0 Card Reader with a GL3224 controller connected to a USB 3.1 Gen 1 port.

Based on the test results with CrystalDiskMark, the read speed obtained was 46.70 MB/s and the write speed was 11.73 MB/s. Meanwhile, in the Cross Platform Disk Test, the read speed reached 40.87 MB/s and the write speed 8.02 MB/s. Although it does not reach the theoretical maximum performance, these results are quite representative for light daily use.

Device Test:

Device: Lenovo IdeaPad Slim 3i 14ITL6
RAM: 12GB DDR4 3200MHz Dual Channel (8+4)
OS: Windows 11 22H2
USB: USB 3.1 Gen 1
