About Hardware GeForce MX350 [Disk]

The NVIDIA GeForce MX350 is an entry-level GPU designed for thin and light laptops, delivering significant graphics performance improvements over the processor's built-in iGPU. The GPU is based on the Pascal architecture with 640 CUDA Cores, and features 2GB or 4GB of GDDR5 memory with 64-bit bus width. The MX350 is generally used for light graphics tasks such as photo editing, light video, and casual gaming, and provides GPU acceleration for CUDA-enabled creative applications.

But in this particular test, a portion of the video memory (VRAM) on the GeForce MX350 was configured as a VRAMDisk. The concept of a VRAMDisk is similar to a RAMDisk, but it uses the VRAM of the GPU as a super-fast storage medium. VRAMDisk allows the creation of temporary, high-speed drives that can be utilized for technical experiments, speed testing, or graphics caching in certain scenarios. Although its capacity is limited and volatile (data is lost on reboot), the high bandwidth and low latency of VRAM provide compelling performance in certain contexts.

The tests were conducted on a Lenovo IdeaPad Slim 3i 14ITL6 laptop with Intel Core i5-1135G7 processor, 12GB DDR4 3200MHz dual channel RAM, and Windows 11 22H2 operating system. The VRAMDisk was created from a 2GB GeForce MX350 GPU, with virtual disk sizes of 1GB and 1.5GB, using special software called GPU RAM Drive.

Benchmark results with CrystalDiskMark recorded read speeds of 1113.58 MB/s and write speeds of 995.48 MB/s, showing the high bandwidth potential of VRAM as a temporary storage medium. Although the performance does not match DDR4-based RAMDisks, VRAMDisks remain a unique and attractive solution for certain technical purposes, especially for users who want to utilize idle VRAM for fast I/O processes. With its dedicated laptop GPU form factor and PCIe x4 Gen 3.0 interface, the GeForce MX350 VRAMDisk opens up new exploration possibilities in the world of experimental graphics-based high-speed storage.

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.
