SAMSUNG (MB-ME128GA/AM) 128GB 100MB/s (U3) MicroSDXC EVO Select Memory Card with Full-Size Adapter

I bought this card four months ago and wasnt experiencing any issues until just recently that I started to notice my phone (Galaxy S9) getting slower, so I performed some tests and everything downloaded to the card would download at very slow speeds as low as 1Mbps, but if I used the internal storage instead, the same file would download much faster over 95Mbps.

Cant say much but my phone love this card works fine get lots more storage

Good but the write speed is not as axpected.

What can be said about storage in a review? Does it store your info? Check. Does it do it reliably? Check. Is the price worth the storage? Check. If you are looking to upgrade storage for a device, say the Nintendo Switch, this should be all you need for some time.

Husband bought this to put in our surveillance camera on our property. Seems to work good, havent heard any complaining or seen it in the trash, so guess it works! Yay!

Dropped into my Surface and BANG instant storage space. Took the 64gig dropped that into my phone and had no issues with either device.

I just upgraded my phone from a 16gb rom to one that has a 64gb rom. Previously I used a regular transcend 32gb for my photos and my Android TWRP backups. That would not cut it with my new phone. I transferred everything over, pretty fast by the way, and this works flawlessly.

i loved that it comes with adapter to fit bigger slots.

I am baffled that such a tiny card can have such a large capacity.

Works fine in my phone. I have over 80gb of music and a ton of photos on the card. No issues
