## Description

Product Description An desertcart Brand. From the Manufacturer desertcart Basics

Review: Something to know - its a great micro sd card but something to you should know about it is the full size adapter doesnt let you unzip files or format on the card so youll want to get a different full size adapter if you plan on doing anything like that, other than that is has ok speeds and works great if you get it at a good price
Review: Surprisingly great performance at an unbeatable price — top value microSD! - Excellent value for a 256GB microSD card — I honestly was not expecting this level of performance at this price point. The desertcart Basics branding had me a little skeptical at first, but after putting it through its paces, I am genuinely impressed. Speed & Performance: The card delivers on its A2 and U3 ratings. Read speeds are consistently near the advertised 100 MB/s, which makes file transfers fast and smooth. I use it in my dashcam and security camera and have experienced zero dropped frames or buffering issues. The A2 application performance rating also means it handles app loading and random read/write tasks reliably. Storage & Reliability: 256GB is plenty of space for extended video recording, photos, and app storage. I have been using it daily for several months with no data loss, corruption, or errors. It gets warm but never hot, even during continuous 4K recording sessions. Compatibility: It comes with a full-size SD adapter which is a nice touch — useful for transferring files to a laptop or camera. Compatible with a wide range of devices including smartphones, tablets, dashcams, drones, and action cameras. Value for Money: This is where the card truly shines. Compared to branded alternatives like SanDisk or Samsung at the same capacity, this card offers comparable real-world performance at a significantly lower price. For everyday use cases like dashcams, security cameras, or extra phone storage, there is simply no need to pay a premium. Highly recommend this card for anyone looking for a reliable, fast, and affordable storage solution.

- 4K & Full HD Ready — Optimized for high-bitrate video recording and burst-mode photography. Handles RAW files, time-lapse sequences, and smooth 4K UHD playback without lag or frame drops.

## Questions & Answers

**Q: Will this  work on a Dashcam?**
A: I would only use this for 1080p dashcams. Anything 1440p and higher, find a faster one. The "endurance" cards are useless if they can't support the write speed. I learned the hard way.

**Q: What company makes these? i get that it’s amazon, but is this samsung or another company?**
A: Longsys Electronics makes these cards.
They also make the chips used in the Lexar brand

**Q: do i use this for more kindle devise memory?**
A: Kindle accepts standard size SD cards, not Micro SD cards. However the adapter that comes with every Micro SD card, allows the Micro SD to be read inside devices that only use standard size SD cards... 
Since the adapter turns your Micro SD into a full size card you ​could use it with a kindle, but it needs to be INSIDE THE ADAPTER. 
The adapter allows interoperability between devices, so you can transfer bulk files easily from your kindle to something needing a micro SD, like a cell phone.  
It mustn't ever be inserted to a kindle as a microSD without an adapter, it'd get stuck in the slot, and you'd only have on board storage available. 
If you're at all unsure about how to use the adapter, or don't need to use it in other devices at all, full size SD cards (which don't need any adapter) are actually cheaper the their micro SD counterparts.  
Here's an example of a full size SD card, that you could insert in your kindle without an adapter (it costs a bit less too). I hope this info helped someone!

**Q: Can this be used for Galaxy tab A8?**
A: yes ... a microSD card fits
