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.
Review: Actually achieves advertised speeds of up to 170MB/s for UHS-1 cards!! - So excited this worked! I was worried it wasn't going to. Just make sure you're using a USB 3.0 port (usually will be blue on the inside). A little concerning, and I will update my review if it causes any issues, but the reader got quite warm during an only 13.4GB upload to my computer. Edit: After performing a much larger upload of 134GB, the performance did degrade as the card reader warmed up. However, it would return to ~170Mb/s after cooling down a bit.

### ⭐⭐⭐⭐⭐ Perfect USB microSD Reader for Tesla Model S.
*by S***O on June 27, 2025*

I bought the SanDisk MobileMate USB 3.0 microSD Card Reader to use with a 256GB SanDisk High Endurance microSD card in my Tesla Model S — and it works perfectly! The Tesla instantly recognizes the reader when it's plugged into the front USB port, and both Dashcam and Sentry Mode start recording automatically. No setup hassle, no errors — just simple plug-and-play. The build quality is solid, and transfer speeds are excellent when moving video files to a computer. It’s compact enough to fit neatly in the center console without getting in the way, and it doesn’t overheat even after hours of continuous use. If you're setting up Dashcam or Sentry Mode on your Tesla and prefer using a microSD card setup (which is more reliable than USB flash drives), this reader is exactly what you need. Super reliable, fast, and affordable. Highly recommended!
