    • Works great
I recently purchased the Silicon Power 256GB Micro SD Card, and it has been a reliable and high-speed storage solution for my various devices. This memory card is specifically designed to meet the needs of devices such as Nintendo Switch, cameras, Steam Deck, and drones. The storage capacity of 256GB is ample for storing a large amount of data, whether it’s games, photos, videos, or other files. It provides sufficient space to accommodate my growing collection of digital content without having to worry about running out of storage. The high-speed performance of this micro SD card is impressive. With a U3 rating and speeds of up to 100MB/s, it delivers quick data transfer rates, allowing for smooth and seamless operations. Whether I’m transferring files to or from the card or accessing data directly from it, the read and write speeds ensure minimal waiting time. The inclusion of an adapter is a convenient addition. It allows me to use the micro SD card with devices that have a standard SD card slot, providing compatibility and versatility. This is particularly useful when transferring files to a computer or other devices that support SD cards. In terms of durability, the Silicon Power micro SD card has proven to be robust and reliable. It is resistant to water, temperature fluctuations, shocks, and X-rays, ensuring that my data remains safe and protected even in challenging environments. This durability adds to the overall value and longevity of the card. One aspect to consider is that depending on the device you’re using, the actual usable capacity of the card may be slightly lower than the advertised 256GB due to formatting and system requirements. It’s always good to account for this when managing your storage needs. Overall, the Silicon Power 256GB Micro SD Card is an excellent choice for those looking for high-speed and reliable storage for their Nintendo Switch, cameras, Steam Deck, drones, and other compatible devices. With its ample storage capacity, fast data transfer speeds, included adapter, and durability, it offers great value for the price. I highly recommend it for anyone in need of expanded storage capabilities for their digital devices. ... show more

    • 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. ... show more

    • Love their products!
I have been constantly purchasing silicone power products for years, they are so great, cheaper than some of the other name brands companies, and work just as well. I even use their hard drives in my computer, but their SD cards are just as great and I have never been disappointed by them especially for the price ... show more

    • Good for a Value MicroSDXC
If you're looking for a decent MicroSDXC this Silicon Power card is a viable choice. I needed something I could carry around that had lots of storage at a decent price. The observations I have are this - it does that. What it does not do is really live up to the "up to 100MB/s" with the write speeds never getting close to 80MB/s but closer to 60MB/s. If you need speed, choose something with the A2 moniker and check the ratings. FYI - the system I am using and the reader I have both are more than capable using other cards to attain higher speeds to it's not the reader or the PC. Overall, I've used many of the Silicon Power and for this, I say they are a good value card if speed is negotiable. BOTTOM LINE: A good value choice with okay performance and great storage for the money but underperforms.
