Review: Worked perfectly in my testing and in my tablets! - I got this 128 GIG card to use with my tablets. So far it has worked perfectly in my testing. I always keep a couple of spares around for my future buys and I seem to give a lot of my SD cards away to family and friends. I picked up this 128 GIG at a great price and I just couldn’t pass it up. I own about 100 SD cards and I always do a speed test to verify the reading and writing speeds before I install the memory. This card checked out extremely well. The fastest write speed on this card was 73.143 MB/Sec and the fastest reading speed was 93.368 MB/Sec. I have attached the graphical test data for your information. I used a USB 3.0 port with a USB 3.0 card reader for the test. Overall, this card worked well and I rated it five stars. If I have any future issues I will update my review. I hope my review and photo of the test data helps you. Out of 100 plus SD cards I have purchased from Sandisk I have only had one fail. With Sandisk’s 10 year warranty they replaced it and sent me a new one at no charge. That is the advantage when you purchase high tech from a top company that stands behind their product. I simply called them and returned the old chip and they sent me a new one. I am amazed at how well these work and how low the price has gotten on a sale day. Putting one of these into your phone or tablet is a wonderful upgrade to the device’s storage capability. Almost no one needs a 128 GIG chip but at sales prices you can’t pass up getting them. This is a great product and it makes your smart devices even more powerful. This is a simple and easy upgrade for your smart devices. Review: Great Product and Excellent Price - This memory card stands out as a true champion, seamlessly blending premium quality with exceptional value. It's an outstanding purchase that delivers not only on speed but also on dependable, consistent performance, all while maintaining an incredibly affordable price point. If you're in the market for a top-tier microSD card to significantly enhance the capabilities and overall user experience of your devices, your search ends here. This particular card is, without a doubt, an absolute winner and a must-have for anyone seeking reliable and high-performing memory solutions. ## Features - Ideal for Android Smartphones and Tablets.

Supports very clear video at 1080p and 1296p (I didn't try 720p). My wife and I were both impressed. I haven't taken it for a ride in the car yet but am happy with what I see setting it up to look out a window at the street - daytime, night time, the WDR adjusts to the bright or limited light fine. I was able to get it to take a 128 GB microSD and ran it through a full day plus without quite filling up (@1296p). I'm happy with that. I had a problem getting wifi to work initially but maybe it was cause the battery wasn't fully charged. Read the instructions to make sure you are connecting the correct SSID. Anyway after several attempts I was able to access the wifi and it has good range. I plugged it into the usb charger (mine) using the provided cable. I was able to connect with my phone using the Akaso app and walk around the house (at least 20 ft) without any break in wifi. Even stepped into another room and it was fine. So since primary use would be in the car I think its great. I downloaded several 3 minute videos and its fast enough for one or two clips. If you want all of the clips, take it to a computer and download direct from the microSD. By putting it in the window I was able to get GPS lock, proving that it did sync with GPS. I played it back later on the COBY player and it pulled up the location on Google maps fine for both locations I tested the GPS - again, I did not use it moving in the car yet. The COBY player is not the most stable, seemed to hang after a couple of video clips. If you just want to see the video (not the GPS) use VLC. Much better image. Time synced perfectly when I made the phone wifi connection. To repeat - great video clarity. Wish I had purchased a second one at that price. And looking forward to putting it in the car. ## Frequently Bought Together - [Older Version] SanDisk 128GB Ultra MicroSDXC UHS-I Memory Card with Adapter - 100MB/s, C10, U1, Full HD, A1, Micro SD Card - SDSQUAR-128G-GN6MA - Anker USB 3.0 SD Card Reader, 2-in-1 SD Card Reader for SDXC, SDHC, MMC, RS-MMC, Micro SDXC, Micro SD, Micro SDHC, UHS-I Cards - Card Reader, Micro SD Card Reader - [Older Version] SanDisk 16GB Ultra microSDHC UHS-I Memory Card with Adapter - 98MB/s, C10, U1, Full HD, A1, Micro SD Card - SDSQUAR-016G-GN6MA --- ## 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.uk/products/45412253-older-version-sandisk-128gb-ultra-microsdxc-uhs-i-memory-card](https://www.desertcart.co.uk/products/45412253-older-version-sandisk-128gb-ultra-microsdxc-uhs-i-memory-card) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-10*
