About Hardware Sony Vaio 4GB / SMI USB DISK
The Sony Vaio 4GB/SMI USB DISK is a small capacity 4GB flash drive, which is more commonly found in older devices or used for basic purposes such as storing small document files or important file systems. Despite the “Sony Vaio” name, this flash drive actually falls into the unbranded or OEM universal drive category, as there is no official manufacturer that clearly identifies this product.
This flash drive is known as a native capacity fake USB, which means that while it may physically resemble a large capacity, it actually only has 4GB of usable storage space. With such a significant capacity limitation compared to today's standards, this flash drive still has a role to play in specialized applications, such as a lightweight operating system installation media, recovery tool, or as a configuration file store.
Tests were conducted using a Lenovo IdeaPad Slim 3i 14ITL6 device, 12GB DDR4 Dual Channel RAM, Windows 11 22H2 operating system, and a USB 3.1 Gen 1 port. Based on tests with CrystalDiskMark, this flash drive recorded a read speed of 24.74 MB/s and a write speed of 9.42 MB/s, which is low but sufficient for basic use that does not require large amounts of data transfer.
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
