I am always looking for a deal, but it must be of quality also. I’m usually very thorough in my investigation of things but, I do fail myself sometimes. I am not overly content with this micro SD card but, It’s not at all the fault of the card or the maker. I mean, it’s working as it should and I Hope it continues. No, it’s the fact that I didn’t read and understand the information correctly. It clearly says it “Reads” up to 85MBps. I simply didn’t realize it said READ only. Being that the READ rate is often 2,3, or even 5 times or more than the WRITE rate, which is the true measurement when you’re transferring files. I was a bit frustrated when I saw this thing writing at 9MBps to 14MBps. People seem to be happy with its longevity so, I will be happy to keep it and Know, when I need to transfer big files, to bring a lunch. Haha! You never know, if it lasts and the price is right, I may buy another in the future. I just Really like to get things done quickly. Especially when I Know I can easily have that technology to save precious time. I will promise this, if it handles a great deal of work, over a long period of time, I will be back to tout it, as I will be back to inform of a fail. I only ran it a couple of tests and it’s in a camera now. Hopefully it will perform better on its next test. So far though, it works fine and the only reason why it’s only receiving 3 stars, is because I don’t like a slow drive but, as I’ve stated at the start, it’s Not their fault. It’s exactly what they advertise and for honesty, they get 5 stars, Always. I hope this helps you!
This SD card was cheap and it works really well. I have a GoPro Hero 3+ and I like to record in HD with really high frames per second, and this SD card hasn't stuttered or missed a shot once. I've used it in my Galaxy Note 4 as well without any kind of problems! I don't have that much to else to say about it, it works well and is cheaper than the Sandisk alternatives.

This 256GB microSD card has 235GB of usable space after being formatted to exFAT. It averaged 95/75 MB/s sequential read-write after multiple CrystalDiskMark runs with random access times being around 7/2.5 MB/s. This is within the advertised U3 / V30 specifications so it is good enough for DSLR and video use. I can also confirm it works on my Nintendo Switch after reformatting. Benchmark & capacity verification screenshots attached.
Went bad a few months after purchasing.Instead, the sd card occasionally disconnects from the device, requiring a reboot or re-insert. It wasn't until around late 2018, when I bought a replacement device, that I realized it was the SD card and not the device. I suppose for the price, it isn't a big deal to have to deal with, but still something to consider. Learn from my lesson. If your SD card starts having problems, suspect the SD card, not the device. Recently (Started in October 2018), the SD card has been corrupting, losing several files.
found these online on sale. works great - as well as any of the high priced :brand name ones. don't be fooled by the name on SD cards. they are all made by 2 or companies and everybody buys them and puts their own name on them. this is a great card for the money. works great in any thing I have used it in. - smartphone, camera, tablet, etc.
Thanks for helping to fix my issue. Item didn't arrive like amazon said, but SP fixed it and sent me a mew one that same day. WOW, I'm impressed! Plus, I believe SP to be the most stable brand of cards when it comes to possible corruption of the cards from unmounting improperly or accidentally, and using between multiple operating systems, and card readers. Which is a horribly common Micro SD card problem no matter who manufactures it. The SP cards really move as fast as they say they do, and are built to last and when my tablet improperly unexpectedly unmounts it with an OTG reader plugged in, the SP cards immediately rebound and remount without messing anything up, or corrupting files. I have a Samsung card I recently purchased that is unstable and and always corrupts the files or just wipes them. It won't work between different systems and is constant trouble. Silicone Power is the way to go and they have been more reliable to me than other brands.. I'll only buy their cards from this day forward, instead of just getting whatever is on sale.
It is what it says it is. You get very good Class 10 performance at a value price. PNY offers a competing unit with up to 90Mb read speed less the adapter and it cost roughly six dollars more at the time I purchased the Silicon Power unit. I chose the Silicon Power over the similar PNY and have not been disappointed in my usage which is as a secondary storage drive in my tablet's MicroSD expansion slot. I used to buy nothing but SanDisk, but after a few failures and having to get warranty support, I opted to try something else. Silicon Power offers a lifetime warranty and while SanDisk did honor their lifetime warranty, SP comes in at a slightly better price point and head to head performance than the SanDisk Ultra line.
For the time I had it, the card was fine. It was reasonably fast and did it's job! Until I started getting cannot read errors. It's stuck now in read only mode. After trying to fix it with lots of google searching I could not fix it. It's not that expensive so it's not a terrible loss, and it lasted about 4 months. Replaced with a Transcend 64GB and haven't had any problems since!
