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.

About Hardware SanDisk MicroSDHC 4GB

The SanDisk MicroSDHC 4GB Class 4 is a small yet powerful flash memory card designed specifically for devices such as cell phones, digital cameras, music players and other electronic devices that support the microSDHC format. With a capacity of 4GB, this card is enough to store hundreds of photos, dozens of songs, a few short videos, and lightweight applications - making it an ideal solution for everyday storage needs, especially on previous generation devices.

As a Class 4 memory card, this microSD guarantees a minimum write speed of 4MB/s, enough to handle standard activities such as recording SD videos, saving camera shots, or loading application data on mobile devices. SanDisk's proven flash memory technology makes this card resistant to shock, vibration, and light to moderate wear conditions, suitable for field use as well as for personal multimedia collections.

In performance testing using a VENTION USB 3.0 card reader (with GL3224 controller) connected to a Lenovo IdeaPad Slim 3i 14ITL6 laptop (Intel Core i5-1135G7 processor, 12GB DDR4 dual-channel RAM), the benchmark results showed consistent performance and within its class specifications. Through CrystalDiskMark, the card recorded read speeds of 19.50 MB/s and write speeds of 5.66 MB/s. Meanwhile, in the Cross Platform Disk Test, the read speed reached 18.71 MB/s with a write of 4.16 MB/s.

To ensure authenticity and actual capacity, verification was also done using H2testw, which showed satisfactory results: read speeds of 18.8 MB/s and write speeds of 4.51 MB/s with no sector errors or damage to its 4GB capacity. This confirms that this memory card is not only genuine, but also functional and stable to use for important data storage.

With stable performance, enough capacity for lightweight needs, and a very affordable price, the SanDisk MicroSDHC 4GB Class 4 remains a relevant choice for users who need simple, durable, and power-efficient additional storage, especially on older devices or as a portable backup medium.
