[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

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.

- I have tried so many different SD cards from various manufacturers, at various price points, in the name of trying to save a few bucks. It was really important to me back when a 128GB card cost $50 or more. They all do the same thing, so what’s the difference, really? What I've found is that it can be extremely aggravating to put up with when the card does not perform well or does not perform at all. I have heard warning stories about cards that are advertised as one size and actually are another size, causing data loss. With that in mind, I have never tried using the very cheapest card or too-goo-to-be-true card deals. But I have purchased cards on sale at the drugstore or even tried some strange brands. What I have come back to is that it’s just not worth the trouble now that prices have dropped so low. When I am trusting 128 GB of data to a single card, it’s just not worth my time and aggravation to have a card that won’t perform. Furthermore, SanDisk cards like this one are all FAST ENOUGH. I’m not a pro photographer, and I don’t have time to figure out whether a card is Class 1 or Class 3 or whatever. I just want it to be good enough that it can keep up with my devices. I have now purchased several SanDisk cards, and each and everyone of them has arrived in perfect condition and works perfectly every time. They are faster than any other card that I use and I've never suffered data loss. I am putting this card into my Fiio X5ii Digital Audio Player, and it works just fine. During the initial data transfer I have already noticed that the speed is adequate, and I never experience skipping when playing uncompressed high-resolution audio files. I have the same card for my Nintendo Switch, and it works perfectly. The prices on these are so good now you have no excuse but to buy good name brand like SanDisk. Just buy it and don't worry about it.

Item works as intended.

I recently purchased the SanDisk 128GB Ultra MicroSD card, and it’s been excellent. The card offers plenty of storage for my phone, camera, and other devices, and the read/write speeds are fast enough for smooth performance with photos, videos, and apps. Installation was simple, and the card has been reliable with no errors or data loss so far. It’s compact, durable, and comes with an adapter for easy use in standard SD slots. Overall, it’s a high-quality, dependable microSD card that provides great storage at a reasonable price.

I got these for a hi-res dash cam set thinking this was overkill. I got a "clipping warning one day because there was a lot of data flow and this card couldn't keep up. To my surprise, this wasn't fast enough. The dash cam needed a V30, U10 or higher card, which is fast enough for most video cameras. So, these work great in EOS canon digital cameras or equivalent with bottomless capacity. I went a year with one camera before downloading all the photos. So, if you don't need 4K movie camera speeds, this card should do the trick. Check your hardware requirements for speed & enjoy

Good value for the capacity and write speed

Better than I expected. 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.

Good SD card, fast and reliable
