About Hardware SanDisk Ultra Dual Drive Go OTG USB Type-C USB 3.1 128GB

The SanDisk Ultra Dual Drive Go 128GB is a versatile OTG flash drive with USB Type-C and USB Type-A support, enabling easy data transfer between devices such as smartphones, tablets and laptops. The flash drive offers transfer speeds of up to 150MB/s, making it ideal for fast and efficient transfer of large files.

In tests conducted using the Lenovo IdeaPad Slim 3i 14ITL6 with 12GB DDR4 dual channel RAM and Windows 11 22H2 operating system, as well as connectivity via USB 3.1 Gen 1 port, the device performed quite well under real-world usage conditions.

Test results through CrystalDiskMark recorded a read speed of 155.93 MB/s and a write speed of 74.86 MB/s. Meanwhile, through ATTO Disk Benchmark (64M test), the device recorded a read speed of 82.05 MB/s and a write speed of 23.02 MB/s. Although it does not touch the maximum theoretical limit, this performance is perfectly sufficient for daily needs such as transferring documents, photos, and medium-sized videos.

With its compact design and dual connectors, the SanDisk Ultra Dual Drive Go is an efficient and practical portable storage solution, perfect for cross-device users who need speed and flexibility.

About Hardware DDR3 SODIMM 1066MHz [Disk]

DDR3 SODIMM 1066MHz is a third-generation memory module with a speed of 1066MHz that is commonly used in laptops and small devices. With the SODIMM form factor, these modules are often the standard choice for mobile computing systems, serving as the main memory for running operating systems, applications, and light to medium multitasking processes.

However, in this particular experiment, two 1066MHz DDR3 SODIMM modules from Micron and ADATA (2GB capacity each) were uniquely configured as a RAMDisk, a temporary storage space that uses RAM capacity to simulate a storage drive with much higher access speeds than SSDs or HDDs.

The 1066MHz DDR3 SODIMM-based RAMDisk test was conducted on an HP 1000 1b05au laptop device, powered by an AMD E1-1200 processor. The system is equipped with a 2x2GB DDR3 SODIMM 1600MHz RAM configuration, but due to processor architecture limitations, the memory only runs in single channel mode with an effective speed of 1066MHz. The operating system used is Windows 7, and to create and manage the RAMDisk, two popular applications, SoftPerfect RAMDisk and ImDisk Virtual Disk Driver, were used. The configured RAMDisk size was 2GB, utilizing some of the available RAM capacity.

Even though the device specifications are old and have limited memory bandwidth, the RAMDisk configured in this system was still able to show excellent performance in the read and write speed benchmarks. Based on tests using CrystalDiskMark, the read speed reached 746.24 MB/s, while the write speed touched 828.18 MB/s. In a follow-up test using ATTO Disk Benchmark with a 64MB block size, the read speed increased to 1020.00 MB/s, and the write speed reached 1080.00 MB/s. These results prove that even on older systems, RAMDisk configurations are still capable of delivering very high I/O performance, far surpassing conventional storage such as HDDs or even some SSDs.

Analysis

The results show that a 1066MHz DDR3-based RAMDisk is still capable of delivering data transfer speeds on par with entry-level NVMe SSDs, even outperforming many SATA SSDs and leaving conventional HDDs far behind. This makes RAMDisks an ideal solution for temporary use such as:

• Application caching,
• Temporary file storage,
• Fast computing with high I/O,
• Software or script testing without the risk of contaminating the main file system.

Although limited to a small capacity (2GB in this test), RAMDisk is still very useful for specific needs, especially for users with more than enough RAM or older devices that want to maximize their performance.

Test on:

Device: HP 1000 1b05au
Specs: 
CPU: AMD E1-1200
OS: Windows 7
RAM: 2x2GB Single Channel 2 DIMM 1066MHz (Does not support dual channel due to limitations of the CPU, currently running single channel mode and 1066MHz)
