Review: Great build quality and faster than expected - I was really impressed with the overall quality of this device. It feels solid, premium, and well-made right out of the box. I used it to back up data from my mobile phone, and the file transfer speed was faster than I expected. Setup was simple, and it worked smoothly for moving my files without any hassle. Overall, this is a great product if you need a reliable way to back up or transfer data from your phone. I would definitely recommend it.
Review: Tiny and Mighty Flash Drive - Tired of those average flash drives... Yes! The ones with limited space and take forever to transfer all of your files? Say no more! With its 128GB to 1TB capacity and USB 3.2 Gen 2 interface, which offers read and write rates of up to 460MB and 360MB, respectively, the SSK External Flash Drive completely alters that. It's ideal for on-the-go use because it can be slipped into your pocket or attached to your key chain. This gadget is incredibly versatile, making it ideal for storing and playing documents, videos, and images in one location. Overall, this should provide consistent performance, while some people may discover different to comparable results. Several people have mentioned that this drive becomes hot, but exactly how toasty does it get? In the last two images, I recorded the base temperature 5 minutes after first plugging it in, which was 32°C. Then, I thought it wouldn't have made sense to take recordings of the tempture during the first test, so I ran two full tests with 9 runs per each SEQ (SEQUNTIAL) and RND (RANDOM) read/write of the 16 GB as a drive burner, each test taking about 10 minutes. During the second test, I recorded the temperature at 51°C which was its peak but hovering more around 50°C. However, in just a matter of one to two minutes its already cool due to its Zinc alloy outer coating. If your worried about the dual USB A and C ends not having the same speeds, have no worries! I ran both ends into the back end of my B450-F Gaming Motherboard which has USB A and C 10Gbps ports. The speeds have about 1% deviation in speeds if none at all since these tests aren't perfect, meaning the storage chips are slower than the interface so for complexity reasons in this review I've chosen to keep it simple. For anyone in search of a reliable pocket-sized device that offers both high speeds and large storage capacity, this is definitely the one to consider. Its performance is unmatched, providing fast data transfers and handling demanding tasks with ease. Whether you're backing up large files, running high-capacity tests, or need quick access to your data on the go, this device delivers consistently. There are virtually no alternatives on the market that offer the same combination of speed, durability, and storage in such a compact form. It's a game-changer for those who need portable, high-performance storage.

*by M***P on June 5, 2026*

Very nice and fast. Plenty of room for what I need it for, transfer between desktop and laptop. Simple to use both ends. Transferred 1.2 Gb in seconds, 40.5 Gb from another external slower hard drive in about 4 minutes. Fast enough for my use. Plus the case is a nice touch. Built solid.
