Review: Perfect Memory - I had previously used the 128GB micro sdcard from SP, actually from the same line (the purple one). It worked perfectly fine in my Nintendo Switch but I thought to myself after downloading a couple digital copy of games that a bump up would be better. So after a couple months I bought this 256GB card after my great experience with the 128 card. SP has simply continued to prove to me they make quality storage mediums. Not only did my Nintendo Switch of course gladly accept the card and show the larger amount of space but the read/write speeds have even improved which is always a plus. If you have a Switch then I highly recommend this brand as not only are they quality cards but also they are very affordable. These of course would be perfect to use in a multitude of devices that require extra storage. As for space on these, I always would mention in detail as a learning tip to other customers about how to never expect full space to be available. This card being stated at 256GB will never have 256GB available to the user and that goes for all manufacturers and memory mediums such as USB sticks and HDD/SSD. I usually go into deeper explanation but simply its due to a difference in measurement scale used (manufactures use 1:1 measurements so 256GB to them is 25,600MB of data or 1,000MB = 1GB. When the scale that techs know is 1,024MB = 1GB). And you also always have a chunk of data locked away for its allocated boot sector and internal tools needed to keep its memory working the longest for you. That's the gist of it so keep that in mind and know you're still getting a very decent upgrade on space.
Review: Small But Mighty - I just received the Silicon Power 256GB Micro SD Card U3 SDXC, and it’s been fantastic right out of the box! I’m using it with my GoPro camera and drone, and it performs flawlessly with fast read/write speeds up to 100MB/s. The card has been super reliable so far, handling large files and quick saves without any issues. The included adapter is a nice bonus for easy transfers. For the price, this card is an absolute steal—great storage capacity and performance for the cost. I’d definitely buy it again and highly recommend it to anyone needing a dependable, high-speed micro SD card!

## Questions & Answers

**Q: Why am i only getting 117.4 gb of usable space? a 128 card should have 119.2 gb of usable space. i cannot fit a 128 image on this card because of this**
A: Most disks -- just like internal storage -- take up a considerable amount for the device you put it in to recognize it and for other things. When you bought the device you're using, it has taken storage space,  too. For example, a Kindle Fire will have taken between 3-4 GB already, brand new. 

In your settings, did you set it to store any apps that may be eligible that were already installed before you installed the card? I think I had four and another later. If you click on the card itself under Storage, it will list what's on it now and how much disk space each is taking. I don't know if you're using it for a laptop, android, phone, camera or a Kindle, so I can't be more specific. This article, even though it's regarding a camera, explains about binary storage being different than KB, MB, GB, TB, etc., so it takes up more memory than how we think of iit straightforward. Hope it helpss. I'm no expert on this sort of thing either.

https://www.diyphotography.net/memory-cards-have-less-space-than-advertised-here-why/

I had to type this in myself because it wouldn't paste it into this. I did double-check it, though. I hope it helps.

**Q: how can i activate sd card?**
A: insert your SD card into a SD slot on your PC or laptop. Allow the operating system time to recognize the device and assign it a drive letter. Once the SD card is recognized you should be able to access and transfer files to it. If using as a storage device for a camera, just insert the card and start snapping away.

**Q: can this work on Samsung mobile phone ?**
A: Almost any card including this one will be compatible with a mobile phone handset, but for that application it is better to choose a card rated A2 rather than A1 because this specifically relates to the speed when used for storing applications and data.

**Q: Will this work for my nintendo switch oled?**
A: Dear Customer,

Yes, this card is compatible with nintendo switch oled. Thank you.
