Incredible. 256 gb of storage on a duo usb & usb c drive. Love this little thing. Packs so much power. First test was transferred a 10gb file within 3 mins. Loveeee 10/10 highly recommend

Ive pushed the drive to capacity and can confirm its what it says it is. The USB A & C options are perfect for moving data between my phone and PC, if a data cable is not readily available. The price point vs the amount of data is really good, especially with the speed and versatility of the two connectors. If you need some kinda USB with decent size and use on multiple device types, this would be perfect to pick up.

The 256G Smartphone and PC OTG SSD USB Drive is a portable solid-state drive (SSD) with a capacity of 256GB. The drive features dual connectors, including a USB3.2 Type-C connector and a USB-A connector, allowing you to connect the drive to a wide range of devices such as smartphones, tablets, laptops, and PCs. The drive also features on-the-go (OTG) technology, which allows you to use the drive as a bridge between devices, enabling you to easily transfer files, photos, videos, and music between devices without the need for a computer. This makes it a very convenient and versatile device for people who are always on the move and need to carry their files with them. It also features SSD technology, which provides faster data transfer speeds and a more reliable performance than traditional hard disk drives. This makes it a great option for users who need to quickly transfer large files, such as videos, photos or music. I tested by transfer about 200Gb of large files (each file approximately between 2Gb to 8Gb), and the average transferring speed was around 85Mbps, which is great for these portable flash drive. Overall, the 256G Smartphone and PC OTG SSD USB Drive is a great device for anyone who needs a convenient and reliable way to store and transfer their files. Its also great for people who need to transfer files between multiple devices, its small and portable, easy to use, with fast transfer speed and a large storage capacity

There are two sides to the drive. The smaller connection has a cool hinge design that allows the top to be removed and stay out of the way without losing it. The regular USB end just has a removable cap, which is also called a losable cap. Why in the world would the same hinged cap not be used on both ends? Thats frustrating to me because I will 100% lose this little cap. I know, its in the product description, but I just assumed there would be some sort of cap retention like a small tether or something. For that reason alone, I am hesitant to use this drive. But it works great as far as portable drives go.

I ordered this USB drive because I occasionally have to swap large video files with clients via USB drive. One client has a newer PC but it has only USB-A type ports. I wanted a USB-C drive that I could easily use on my new M1 MacBook Pro that would also work on my clients USB-A ports on his PC. This USB drive fit the bill as it has both USB-A and USB-C connections. When I opened the box I was very pleased to find that the USB drive has no logo on it to mar the plain silver color zinc alloy metal. It looks and feels like a quality product. I plugged it in the USB-C port of my 2021 M1 MacBook Pro and opened Apples Disk Utility app to see what file system it was formatted with. I was glad to find that it was formatted with the exFAT file system. This is the one I prefer because it works with both Macs and PCs and allows file sizes over 4GB. You could always format to a different file system, but this is the one I needed and would be most useful for the largest number of people. Most shouldnt even have to think about this. I next did a speed test using the Disk Utility app. Speeds were decent, showing almost 300MB/s read speed and about 400MB/s write speed. However, the speed falls significantly short of the 500MB/s speeds claimed in the product listing. Its In the multiple tests I ran, it was 20%-40% slower than claimed. Using BlackMagic disk speed test I got results about 10% faster than Apple Disk Utility test. This speed test is optimized for larger file sizes used in video editing. I got average readings of about 330MB/s read speed and 440MB/s write speed using this disk test. This is still not exactly the 500MB/s claimed but its a bit faster than the other speed test. The speeds are definitely due to the USB drive itself as Im using it on a new Mac with 40GB/s thunderbolt 4 ports which are capable of speeds almost 100x faster than the top speeds I got with this drive. For many uses this isnt much of an issue. These are still fast speeds compared to USB 2.0, but if your work requires transferring huge video files like mine does, youll probably want to know that it may take you up to 20% to 40% longer than youd hoped.

This USB flash drive came in a fairly nondescript black box, with no branding on the box or the USB drive itself. I tested with a few different utilities, and it does appear to have 256GB storage. In addition, my speed tests show that it does come close to the 500MB/s read AND write speeds, as advertised. The flash drive itself has a little bit of heft to it. The cap for the USB-C side is not removable and has a swing mechanism design. The cap on the opposite side for USB-A is removable but is magnetic which makes for a satisfying connection. I used both connectors to connect to multiple PCs, Android phones and tablets, iPad Pro, and a MacBook Air with no issues.
