Works as advertised. Verified capacity with h2testw.exe. Benchmarked performance with CrystalDiskMark 5.0.3 x64. Excellent sequential read. Good sequential writes. Mediocre random read and write. This makes it ideal for media storage. I have recorded 4K video at nearly 90Mbps that wrote successfully to the card.

I bought 20 of these for use in classroom. When I tried to install software on them, 3 of them were unusable. Windows reported "a problem" with the device, and I was unable to re-format, adjust partitions, etc. Since they have been in use, 2 more have spontaneously failed. These are inside closed devices, so they're not being removed and reinserted, so there's little chance that this is related to physical damage. The cards just seem to fail out of the box, or after a bit of use. Very disappointing. They were inexpensive, but now I need to replace them and re-build the software for my class. Very disappointing.

I normally don't do any review, but I had to this time. It has been working great for the past 3 or 4 months, but recently, it's doing really, really bad. The devices that it's connected would randomly loose connection. Like, if I was to put 2 gbs worth of files into this, it would transfer for like 15 seconds and then the rate will hit zero and give me an error. I would have to then disconnect it and connect it again in order to attempt to transfer again. Do this like 14 times until all 2 gbs is fully transferred. NOTE: I've been using the original adapter and this other adapter that I have. So it's not bad adapter because I have a 32GB and that works fine with either of the adapters.

When I do this, I always have to pick "replace file" or the files would be corrupted. Sometimes, my device won't even read this no matter how many times I unplug and re-plug this back. Scan and Repair helps, but only up to a full minute of transferring files. As of right now, I can't return this because of the 30 day limit. It's still functional in a way, but I have to get something sooner or later. This sucks when you want to access something, and the device indicates it's not connected. I've formatted this like 6 times so far. I don't think it's going to help anymore. I recommend buying SanDisk instead. It has not failed me yet.

Exactly what it says it is, and best value. After ordering a MicroSD card from fraudulent Amazon Sponsored Link company, I did a check on the company (UDW) and found they were knowingly selling fake cards. Doing FAKEFLASHTEST on the 256Gb card showed it actually had 6Gb of available storage, and the 64Gb card could only hold 2.8Gb. I disputed the credit card charge on those, and ordered this Patriot memory card. I have always had good experience with Patriot, owning two Patriot USB flash drives for several years now with no issues.
This card is only half of what I really wanted, but didn't want to pay more than $40. At least I now have dependable storage, and not something that will corrupt my photos and files some time in the future when the storage limit is exceeded.
BTW - I ran the flash test on this card, and everything ran perfectly showing a full 128Gb available storage.

I've been using this Patriot LX Series 128GB High Speed Micro SDXC Class 10 for just over a month now in my Amcrest 1080P PRO HD IP WIFI camera and it has been working great for me. This camera is said to support up to 64GB MICRO SD cards but I like more memory so that is why I put the 128GB card in it.
And so far it is working flawlessly. I've adjusted the camera's video settings to record at a fairly high bitrate and at 25 FPS so I get really high quality playback of video it captures.
With the camera settings I have this Patriot card is storing about 8 days of captured video for me to review and/or download and save to my pc if I need or want to.

It's working great for my needs, what more can I say?

I am experimenting external storage for my arduinos, arduino shields and other owned microcontrollers, so I purchased three Micro SDHD cards (each came with its own adapter). Price for each item posted in the Amazon website was hard to resist. I previously purchased a 64 GB Patriot Micro SDHD for a camera and became satisfied with its performance. For me, the Patriot has performed well, friends and family members enjoy other brands with equal performance as the Patriot. (It is about the product making the customer feel comfortable.) Thank you.

Maybe I have a bad one, but it's a fight daily with this thing.. I have to seat it 2-3 times in my gopro camera, and 5-10 times in my computer adapter to offload the images... I literally just spend 5 minutes trying to get it to recognize on my computer and the frustration made me log in here to give a bad review....

Doesn't work. Installed an OS on 3 of these and all three work the first boot but after that nothing. When you put it back into a computer it doesn't read anything. Card is not detected. If you reboot it comes up with an error saying the drive needs to be formatted, has no readable data. I have installed this OS on a few other brand SD cards with no issues.

I bought one of these for my Galaxy Tab S tablet. I like the added space but transferring large files like movies and videos can be a real pain. It's extremely slow. I have a 64gb Samsung Evo U1 card and it does the transfers in a fraction of the time. if you don't care about transfer speed and are just interested in storage of pictures videos you take with your device, then it's a great buy. Otherwise stay clear of this and go for a different brand.

Unlike what some users were saying .. these were official from Patriot company .. item was original with acceptable Write Speed .. ( ~ 11MB per second ) and good Read Speed for the price .. I performed some tests and in comparison with other cheap SD , these were much more reliable and faster ..
