Perfect Memory
Capacity: 256 GB Style: microSD UHS-I
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

Small But Mighty
Capacity: 256 GB Style: microSD UHS-I
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! ... show more

Good so far.
Capacity: 256 GB Style: microSD UHS-I
I’ve had no problems with this SD card. It is a great value and based on the reviews I took a chance on an unknown (to me) brand. I’ve had some bad experiences with off-brand SD card and hard drives and this one has not disappointed me. I’m not using it to store critical documents but for short term storage and backing up it has been great. ... show more

Good for a Value MicroSDXC
Capacity: 256 GB Style: microSD UHS-I
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.

DO NOT BUY! WASTE OF MONEY! LOSE YOUR DATA!
Capacity: 512 GB Style: microSD UHS-I
PURE TRASH! I got to use it one time. It took several attempts to get it to identify and be recognized in one device (phone) and one try in another. So not very universal. I transferred a file system backup to it. Moved it to the second phone that it was most compatible with and had it there for about 6 hours before the chip disappeared. Wiping out all my data becoming incompatible with any device complete trash! Unrecoverable data. The device cannot be identified in any type of reader or electronic device it's trash! And my backup data that I put on it is now lost and it was my only copy once I have transferred it I deleted it from my other source. So I have nothing but hard feelings against this manufacturers piece of trash device. Obviously I'm choosing kind words to say! So truth being, it is NOT easy to install. The size compatibility is becoming more common. I can't tell you about data transfer rates as I only got two store data on here once and it was kind of slow. But again I would not recommend this device for anything. You put data on one of these to save it not lose it! You buy one of these for compatibility and you don't get that with this! We'll see what the manufacturer has to say about their piece of trash that I wasted my money on. ... show more
