This is a comprehensive guide to microSD cards, covering various aspects such as their features, performance, compatibility, and testing methodology. Here's a summary of the main points:
**What are microSD cards?**
MicroSD cards are small, portable memory storage devices that use the SD card interface.
**Types of microSD cards:**
* UHS-I: The base model with a theoretical maximum speed of 104 MB/s.
* UHS-II: Faster than UHS-I, with a theoretical maximum speed of 312 MB/s.
* SD Express: Even faster than UHS-II, but requires a compatible reader and device.
**How to choose the best microSD card:**
1. Consider the intended use:
* Photography: Look for cards with high write speeds and capacity.
* Gaming: Opt for faster cards like UHS-II or SD Express.
* General use: A balance between speed and capacity is sufficient.
2. Check compatibility:
* Ensure the card supports your device's interface (e.g., UHS-I, UHS-II, SD Express).
* Verify that the card can be used in different environments (e.g., extreme temperatures, humidity).
3. Look for features:
* Water and dust resistance
* Temperature range
* Random read/write performance
4. Consider capacity and price:
* 128GB is a sweet spot for many devices.
* Prices vary depending on the brand, model, and capacity.
**Testing methodology:**
The guide outlines a comprehensive testing process that includes:
1. Benchmarking: CrystalDiskMark, BlackMagic Disk Speed Test, ATTO Disk Benchmark, and AJA System Test.
2. Real-world tests:
* Copying files (Photoshop, videos)
* Downloading games (Stardew Valley, Apex Legends)
3. Verifying card capacity and performance using tools like H2testw and FakeFlashTest.
**Recent updates:**
The guide is regularly updated to reflect changes in the market, such as:
1. New microSD Express cards
2. Price increases and stock shortages driven by the AI boom.
3. Discontinued cards (Kingston Canvas Go Plus, Lexar Professional 1066x).
4. Updates to testing methodology and results.
By following this guide, you'll be able to choose a high-quality microSD card that meets your needs and provides optimal performance for your device.

uhs-ii or sd express for gaming tho 
anything less is just too slow lol
! it's crazy how fast the prices are rising with all these new AI tech devices coming out, but at least now we have a resource to find the best ones for our needs 
. i mean think about it, 128GB is still a great sweet spot for most people, and being able to get that kind of performance in those smaller cards is just amazing 
. anyway gotta give props to whoever's keeping this guide updated, it's like they're spreading hope and knowledge one microSD card at a time 
, but you can't deny the quality these cards bring to the table! 
I think it's wild how much technology has advanced in just a few years, right? Like, we used to think 128GB was huge, but now we're talking about SD Express cards that are insane fast! 
What's crazy is how quickly prices can skyrocket when there's demand for something new. I mean, who would've thought AI would be driving up the cost of microSD cards? 
Anyway, I'm glad there's a reliable guide out there to help people navigate all these options. It's like having a friend in tech 
. It's no wonder people are looking for alternatives or upgrading their storage options. And what's with the testing methodology? I mean, using multiple tools to test performance and capacity is a good start, but what about those newer AI-driven benchmarking tests that come out every now and then? That's some next-level stuff right there 
.
.
. I think the key is to consider what you're gonna use the microSD card for most. If you're a photographer, you'll want something fast and with plenty of storage 
. Can't we just have a standard interface that everyone can use without breaking the bank?! 
But what really got me is the test methodologies, I mean I'm no tech expert but even I can see that some of these tests are pretty brutal 
like copying files and downloading games back to back? That's like trying to finish a whole season of your fave show in one sitting 
. To be honest, I don't really need all the fancy features like water resistance or temperature range. For me, it's just about getting enough storage space to download my favorite games and watch videos without running out of room
