## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Average extra storage.
*by S***. on 3 July 2025*

Good extra storage. Used on mobile, no problems. Good quality, good brand.

### ⭐⭐⭐⭐⭐ Good and much better than my recent patriot micro sd
*by A***A on 8 June 2025*

I got 128gb for 740rs. It is better than patriot v30 a1 which was giving write speed below 30MBps. This one read speed and write speed photos attached.Only problem is the print on the card is very bad quality. As you can see the paint has gone after just 1 insertion. But still there is 5 year warranty so its good value.
