Review: Delivery speed and good product - works as advertised Review: SD to USB transfers or a simple DIY USB Stick - Problem: PCs these days don't usually have MicroSD readers and I needed one because I own phones and tablets. When I want to transfer gigs of pictures/videos to my PC this card reader does that easily and quickly. Speed: I bought this because its USB 3.0 which means I should get 500MB/s. When used with a C10 or U1 MicroSD that only does 100MB/s the card itself is the bottleneck. Even a U3 is 300MB/s peak transfer and a high quality V## MicroSD are the exact same UHS2 300MB/s speeds and means this device is somewhat futureproof for a while. Capacity: ZERO! On the user. I bought a 256GB U3 MicroSD card for less than 20$ to leave in it. Intended use vs actual use: Wanted it so I could transfer files easily but that's not that often. Practical use, I installed CallOfDuty and its 200+GB on the card and run my game off the chip now. I feel like it loads MW3 faster and is a bit smoother. Less than 30$ I kinda unintentionally got a setup that helped my gaming by freeing up space and improving my performance while still allowing me to transfer files from portable devices when I need to. Perfect for what it does and I'd buy another one if I ever need to. Parts are durable and its compact so I doubt it will break since there's nothing really to break. It's nice solid hardware and a great value for the price. ## Features - Compact and durable microSD card reader - Fast UHS-I transfer speeds of up to 170 MB/s* - With USB 3.0, move content up to 10x faster than USB 2.0 readers(2) - Compatible with USB 3.0 and backwards-compatible with USB 2.0 - Two-year limited manufacturer warranty(1) - Dimensions (L x W x H) - 30.48mm x 20.701mm x 8.763mm ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07G5JV2B5 | | Additional Features | Compact | | Best Sellers Rank | #61 in Computer Memory Card Readers | | Brand | Sandisk | | Built-In Media | MobileMate USB 3.0 Reader | | Color | Black | | Compatible Devices | Camera | | Connectivity Technology | USB Type A | | Customer Reviews | 4.5 out of 5 stars 33,281 Reviews | | Global Trade Identification Number | 00619659169039 | | Hardware Interface | USB 3.0 | | Item Dimensions L x W x H | 1.2"L x 0.82"W x 0.35"H | | Item Type Name | SanDisk MobileMate USB 3.0 microSD Card Reader - SDDR-B531-GN6NN | | Item Weight | 1.81 g | | Manufacturer | Sandisk Technologies, Inc. | | Media Type | UHS-1, microSD | | Mfr Part Number | SDDR-B531-GN6NN | | Model Number | SDDR-B531-GN6NN | | Number of Items | 1 | | Operating System | nintendo wii | | Slot Count | 1 | | Special Feature | Compact | | UPC | 619659169039 | | Warranty Description | 2-year limited | ## Product Details - **Brand:** Sandisk - **Color:** Black - **Connectivity Technology:** USB Type A - **Media Type:** UHS-1, microSD - **Special Feature:** Compact ## Images ![SANDISK MobileMate USB 3.0 microSD Card Reader - SDDR-B531-GN6NN - Image 1](https://m.media-amazon.com/images/I/51eG3pEkfxL.jpg) ## Questions & Answers **Q: Is the card reader faster than adapter?** A: If you are using it in a camera many brands of cameras use an adapter for micro sd cards.

It's compact, easy to carry, and worked right away when I plugged it into my computer. I used it to transfer photos and videos from a microSD card, and the transfer speeds were quick with no issues. I also like how small it is because it doesn't take up much space in a laptop bag or camera case. The card fits securely, and I've had no problems with connectivity or reading files. Overall, this is a simple, reliable card reader that gets the job done and is a handy accessory to keep around if you regularly use microSD cards. ## Frequently Bought Together - SanDisk MobileMate USB 3.0 microSD Card Reader- SDDR-B531-GN6NN - SanDisk 256GB High Endurance Video microSDXC Card with Adapter for Dash Cam and Home Monitoring systems - C10, U3, V30, 4K UHD, Micro SD Card - SDSQQNR-256G-GN6IA - SanDisk 128GB High Endurance Video MicroSDXC Card with Adapter for Dash Cam and Home Monitoring systems - C10, U3, V30, 4K UHD, Micro SD Card - SDSQQNR-128G-GN6IA --- ## 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.com.sa/products/80511294-sandisk-mobilemate-usb-3-0-microsd-card-reader-sddr-b531](https://www.desertcart.com.sa/products/80511294-sandisk-mobilemate-usb-3-0-microsd-card-reader-sddr-b531) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-08-07*
