  • Small price, big bang for your buck and NEVER FAILS, pure reliability! (used for Dashcam)
Capacity: 256GB
Nothing better than having a super reliable SD card like a Sandisk Micro SD card! I've never/ever had one corrupted on me, so I'm able to retrieve ALL my data from my Dashcam (which is what I use this specific 256 GB for). I'm able to record in the highest resolution setting flawlessly without any stutters or jams, mishaps or failures. I have hundreds of hours of recording using this because I constantly have files being looped over and over while driving so I can protect myself, or at least FEEL like I have extra eyes watching in the event something were to happen. I can TOTALLY rely on this brand (Sandisk) for pure 100% reliability. The price? Not bad, can't go wrong and a real great investment too. :) Thank you for reading my review. :) ... show more

  • Great for Tapo Cameras
Capacity: 512GB
Bought these for my Tapo Security Cameras. Easy to install and recommended if you're trying to save on paying for a subscription plan. I have 4 cameras, and wasn't willing to pay for 4 different plans as you can't bundle, so I was glad that this was an alternative. You can control the SD card via the Tapo app as to how much you want to record/deleting content/overriding footage after a certain point so you never run out of memory. ... show more

  • Great micro SD card
Capacity: 128GB
SanDisk is the best micro SD card to buy. Never had a problem with corruption or picture quality. It is very reliable and a great value. It also comes already formatted. The other micro discs that are sold with giant memory are not formatted. Formatting a micro SD card is simple and takes about 2 minutes so you have a lot of options. ... show more

  • Quick & Easy
Capacity: 128GB
Once I popped this bad boy in, my life changed. Suddenly, I could store all the memes, photos of my dog, and maybe even a few random videos of my attempts at cooking without constantly running out of space. (Honestly, those cooking fails deserve to be preserved for generations!) It’s super easy to set up—just slide it in, and boom! My phone was like, "Welcome back to the land of plenty!" Plus, the speed is nice and quick. I can transfer files without feeling like I’m waiting for a dial-up connection to kick in. If you’re on the fence about getting an extra micro SD, just go for it! It’s like giving your device a little storage vacation. Now if only it could also organize my chaotic life... but hey, one step at a time! ... show more

  • Fast and reliable storage
Capacity: 256GB
Used this for my GoPro and later switched it into a Steam Deck — works great in both. Speeds are as advertised, and I haven’t run into any issues with formatting or transfer. Handles 4K video smoothly and loads apps fast. If you need solid storage without overthinking it, this one does the job.

  • Perfect for storing my music collection
Capacity: 256GB
I am a mobile DJ and needed a way to store my vast music collection. With this card I was able to store over 2,000 albums (.MP3 files) and over 1,500 singles. The card fits into a slot on my DJ controller and I am now able to carry the complete collection with me internally in the controller.

  • 2tb Extreme MicroSD Card running on Samsung Galaxy Devices
Capacity: 2TB
It's perfect for my Samsung Galaxy devices. I haven't had an issue yet. I have it on my samsung galaxy tab s9+ which it has the 512gb internal memory and then i have the 2tb micro sd card running In all the high volume, high data transfers off of the device and put it on to the disk. The disk has done nothing but make me happy, the high quality 4K@144Hz to 8K@60Hz High definition it's stunning, haven't had no issues with any of the files get encorrupted or unsupported, and I barely put a dent on the memory even after putting 120bg of photo editing images my devices run better than they did.When I first got him, everything goes on the sd cards. And the app, it hasn't even told me about an issue yet. Besides the SSD that I purchased and so between the app and having the microSD card I love it. I just purchased my second. MicroSD card, and I'm going to have it for my external memory for my Samsung Galaxy s24 ultra keep it up, guys so far. Abby product that I had from you. Guys has shown nothing but good things.
