Review: Tiny, sturdy black design slips in my pocket - This SanDisk Ultra Dual Drive Go 1TB is absolutely brilliant! Blazing 400 MB/s speeds empty my phone’s 4K videos in seconds. The reversible Type-C/A connectors work flawlessly with my Android, Galaxy Tab and MacBook—no adapters needed. Tiny, sturdy black design slips in my pocket. Finally, 1TB of reliable storage on the go! Worth every penny. Review: A fantastic, sleek device to transfer files quickly and easily from mobile to laptop/PC. - Excellent drive, superfast connectivity and transfers. Connects to both (as described) to USB-C (mobile) as well as USB-A drive (laptops/PCs). Fits easily anywhere (not a bulky drive) and does not need much space (sleek device). Solid build and format capability, and works well with both windows and android instantly without any hassle. Great to transfer personal files such as photos and videos immediately from the mobile to save on space. Have tried on two different mobiles (Samsung and OPPO) and both mobiles connected seamlessly. My only additional observation would be is to make sure OTG is enabled in settings on mobile before plugging in (e.g. OPPO mobile needed this one additional security step before recognising the drive, the mobile turns this feature off after about 10 minutes - great feature to have for security). Great value for money and functionality. I could connect this drive to USB-C on laptop as well (if available - please see image with drive connected to USB-A, USB-C on laptop). A fantastic solution for anyone looking for an easy solution to save disk space on mobile and easy transfers of files from a mobile to a laptop/PC. Would definitely recommend. ## Features - The 2-in-1 flash drive with a reversible USB Type-C and a traditional Type-A connector. - Seamlessly move content between your USB Type-C smartphone, tablets and Macs and USB Type-A computers. - Free up space on your USB Type-C smartphone so you can take more photos. - Automatically back up photos using the SanDisk Memory Zone app. - High-performance USB 3.2 Gen 1 drive with up to 400MB/s ultra-fast read speeds. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CJ5YH8DP | | Best Sellers Rank | 31 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 1 in Memory Stick Cards 2 in USB Flash Drives | | Box Contents | Product | | Brand | SanDisk | | Brand Name | SanDisk | | Colour | Go Green | | Compatible Devices | Desktops, Laptops, Smartphones, Tablets | | Country of Origin | Malaysia | | Customer Reviews | 4.5 out of 5 stars 50,670 Reviews | | Flash Memory Type | Memory Stick Duo | | Hardware Connectivity Technology | USB Type C | | Hardware Interface | USB 3.2 Gen 1 | | Hardware interface | USB 3.2 Gen 1 | | Item Weight | 5 g | | Manufacturer | Western Digital Technologies, Inc. | | Manufacturer Part Number | SDDDC3-256G-G46AG | | Memory Storage Capacity | 256 GB | | Memory storage capacity | 256 GB | | Model Name | Ultra Dual Drive Go | | Model Number | SDDDC3-256G-G46AG | | Network Connectivity Technology | USB | | Number of Items | 1 | | Number of Packs | 1 | | Product Features | Fast data transfer | | Product Warranty | 5 year | | Read Speed | 400 Megabytes Per Second | | Read speed | 400 Megabytes Per Second | | Special feature | Fast data transfer | | UPC | 619659203924 | | Unit Count | 1.0 count | | Write Speed | 100 MB/s | | Write speed | 100 MB/s | ## Product Details - **Brand:** SanDisk - **Hardware interface:** USB 3.2 Gen 1 - **Memory storage capacity:** 256 GB - **Special feature:** Fast data transfer - **Write speed:** 100 MB/s ## Images ![SANDISK Ultra Dual Drive Go 256GB, USB-C & USB-A, Up to 400MB/s Read Speeds - Image 1](https://m.media-amazon.com/images/I/61ub8hnqt+L.jpg) ![SANDISK Ultra Dual Drive Go 256GB, USB-C & USB-A, Up to 400MB/s Read Speeds - Image 2](https://m.media-amazon.com/images/I/51bVYMlkNoL.jpg) ![SANDISK Ultra Dual Drive Go 256GB, USB-C & USB-A, Up to 400MB/s Read Speeds - Image 3](https://m.media-amazon.com/images/I/61ySM1nGg+L.jpg) ![SANDISK Ultra Dual Drive Go 256GB, USB-C & USB-A, Up to 400MB/s Read Speeds - Image 4](https://m.media-amazon.com/images/I/51bSjUbuGAL.jpg) ![SANDISK Ultra Dual Drive Go 256GB, USB-C & USB-A, Up to 400MB/s Read Speeds - Image 5](https://m.media-amazon.com/images/I/71EtRYsV8kL.jpg) ## Available Options This product comes in different **Color, Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Tiny, sturdy black design slips in my pocket *by K***S on 15 March 2026* This SanDisk Ultra Dual Drive Go 1TB is absolutely brilliant!

Would definitely recommend. ### ⭐⭐⭐⭐ small and light, but fast *by A***R on 19 August 2024* I initially ordered the 512GB version, but it would take too long to be dispatched so I changed to this one. I picked it up from my local post office less than 24 hours of ordering, which is impressive. To my pleasure, this item is much smaller and lighter than what I thought. It is the size of the top two digits of my pinky. I ordered Ultra Dual Drive Go, the cover of which is made of plastic, and it does feel a bit cheap if you look closely at it, but from a metre's distance it looks quite decent. Would prefer a metal cover, though that is a premium which will increase the price I guess. I don't use it daily, so I am not worried about accidentally breaking it. I tried it out on my Macbook Pro, and it transferred data quickly, about 5? GB per minutes if the transfer was from the laptop to it. Slightly slower if I transfer data from another USB to it using a hub. I don't have much experience in data transfer, but this speed has been enough for my purpose. It can get hot quickly, but once unmounted it also cools quickly. I don't want to keep it on for too long to avoid unintentional damage due to heat. Time will tell its reliability. Overall a satisfactory product and will definitely buy SanDisk product again (having had quite a few of them). ## Frequently Bought Together - SanDisk 256GB Ultra Dual Drive Go USB Type-C Flash Drive, Absinthe Green - SDDDC3-256G-G46AG - SanDisk 128GB Ultra Dual Drive Go USB Type-C Flash Drive, Navagio Bay - SDDDC3-128G-G46NBB --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/588952963-sandisk-ultra-dual-drive-go-256gb-usb-c-and-usb](https://www.desertcart.kr/products/588952963-sandisk-ultra-dual-drive-go-256gb-usb-c-and-usb) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-08-24*
