Better stick your phone in the freezer while it is copying 100GB worth of media. **Q: Is the outer shell plastic or metal?** A: its plastic, but a hard plastic. i got one cz i have macbook and a pc. this thing is tough as nails, i have it on my keys and they are thrown around the place. its a good buy ! **Q: How long is the usb C plug. I have a rather thick case on my s9+ and there is restricted access to the usb port. The plug would need to be 8mm long** A: Somewhere between 7 and 8 mm - silver bit, but black part is tapered so it might still fit ?. However, suggest you look for a usb-c extension lead (or male to male & a female to female connector - I use both that work fine together) that fits, so as to solve the prob for all. **Q: dos it work on play back on a galaxy tab for play back** A: Yes, you can access it like a normal drive. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Tiny, sturdy black design slips in my pocket *by on Reviewed in the United Kingdom 15 March 2026* 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. ### ⭐⭐⭐⭐⭐ Fantastic ! *by on Reviewed in the United Kingdom 20 July 2026* It was such a great deal when I bought it! It is very cute with lovely colour. It is working well with Android phone. No hassle to connect or install to the phone at all. Also, fast operating system! ### ⭐⭐⭐⭐ Good storage but hot in touch *by on Reviewed in the United Kingdom 29 August 2025* I’ve been using the 128GB Ultra Dual Drive Go USB-C Flash for a while now, and overall it’s been excellent. The transfer speeds are impressive. It’s very convenient to switch between devices with USB-C and USB-A. It feels well-made and reliable for everyday use. The only downside I’ve noticed is that it can get quite hot during long use, but it hasn’t impacted performance so far. It’s definitely good value for the price. ## Frequently Bought Together - SanDisk 256GB Ultra Dual Drive Go USB Type-C Flash Drive, Black - SDDDC3-256G-G46 - Syntech USB C to USB Adapter Pack of 2 USB C Male to USB 3.0 Female Adapter Compatible with MacBook Pro Air 2024, Microsoft Surface, iPad,Samsung Notebook, Dell XPS and More Type C Devices,Space Grey --- ## 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.co.za/products/164728458-sandisk-ultra-dual-drive-go-256gb-usb-c-and-usb](https://www.desertcart.co.za/products/164728458-sandisk-ultra-dual-drive-go-256gb-usb-c-and-usb) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-14*
