Review: Works, but you do get what you paid for... - This is a superficial breakdown of 30 minutes spent with the card, so take it with a grain of salt. Using it with an adapter into a laptop equipped with a decent SSD, you can expect write speeds that constantly dip as low as 9-10 MB/s and go upwards to 28 MB/s. Read speeds usually sit in the high 20s. Haven't tested it straight into a device, so speeds might improve, as shown by another customer with pictures (70+ mb). As for the capacity, as I see this argument popping up over and over again, please educate yourself why the advertised capacity by the manufacturer is different than the one showed by your computer. A simple google search will give you multiple articles regarding this. For all intents and purposes storage is calculated as you would weight, distance etc, by adding zeros to the end. so 1 Gigabyte (GB) = 1,000 megabytes (MB) etc. However due to how computers work, they will not show these values, but instead: 1 Gigabyte (GB) = 1,024 megabytes etc The bigger the drive is, the more capacity is "lost" in the listing of your device. 128 gb = 1,099,511,627,776 bit 1,099,511,627,776 bit = 137,438,953,472 byte 137,438,953,472 byte = 134,217,728 kilobyte 134,217,728 kilobyte = 131,072 megabyte 131,072 megabyte = 128 gigabyte I made a quick calculation (which could be slightly incorrect, failed math): The amount you "lose" is as fallows: Gigabyte difference = 73,741,824 bytes Since per GB your are "losing" 73,741,824 bytes, then 73,741,824 bytes x 128 GB = 9,438,953,472 bytes, which converted to GB equals: 8.79071 GB (as shown in the picture). Windows machine shows 117 but if we add the "missing" 8.7gb = 125.7, which is closer to the advertised capacity. Also this might be true for write/read speeds as well, and the actual product does not advertise 95MB/s, rather "up to" which is correct. Does the job, but I would use it for complex write and read situations. Only really useful for mobiles and other hand held devices.
Review: Great card at a great price - Excellent micro sd card for my security camera, great price compared to others, highly recommend

### ⭐⭐⭐⭐⭐ Great card at a great price
*by A***A on 16 December 2025*

Excellent micro sd card for my security camera, great price compared to others, highly recommend

### ⭐⭐⭐⭐⭐ Great (maybe overkill) for a 2DS
*by A***D on 2 August 2023*

I recently bought this to upgrade my cousin's 2DS to a 64GB card so they can play around with modding and homebrew. While the 2DS/3DS have class 4 slots, this is overkill in that regard; it is brilliant when transferring files over from the PC to the card. Works well, what more can I say. I also have the 128GB version in my Nintendo Switch and that has been going strong for many years.
