Samsung 128GB EVO Plus UHS-i Class 10 Micro SDXC Card with Adapter up to 80MB/s (MB-MC128D)

I just got a Samsung S8 Plus and wanted to get a storage card to go into it. My Note 5 didn't have the ability to use a card so I needed to get a new one. But which one? There are so many out there! I originally wanted a much more expensive card that I saw but I couldn't justify the price. I just want to store pics, music, and apps on the card and everything is backed up to the cloud on one of my computers so I decided on this Samsung 128GB EVO. It wasn't super cheap but didn't break the bank either for such a large capacity card.It came in retail packaging. A cardboard card with plastic overlay with the small card on one side and the adapter on the other. I didn't have to format this card and it just started to work immediately. I have lots of stuff on there now and it's fast. I downloaded some things to the card and uploaded some things from the card and I found the speed to be great. So far, all is working wonderfully. Naturally, the test of time is the biggest one so I will update if there are any issues as time goes by. Right now. I really feel I mad the right choice and this card fits my needs perfectly.

Upgraded the capacity of my S7 Edge - only 20GB of the 32GB internal storage is available and I used this micro SD card to increase that. Card showed 120 GB available of the 128 GB advertised. Got sequential write speeds of 16MBps+ using Crystal Disk Mark which is more than enough to keep up with my S7 Edge. Camera performance shows no degradation and no worries about running out of space on my phone when taking pictures or shooting 4K videos. Extremely good value for the money that I paid for it ($37odd), no issues so far in the 3 weeks that I have had it with me.

Works just fine... USB connectivity from the music source to the phone was the weak point.So... Advice: Put all your music or data using the sleeve and transfer w/o USB, as much as you can on the initial install.I ran into pains when I removed the card to add albums a 2nd time... (it screwed up my settings and file structure on the phone)If you use USB to write material to your device, it will be slow, but it won't mess with the file structure on your "samsung" phone.If you have any other phone than samsung, this might not be an issue, unless its an Apple, because you won't have upgradable memory, so you're screwed.

This was the fastest load (write) ever...I used the card as storage drive on my Android phone, for pictures, files and all my personal CD library of all my music. Cards seem to die after about a year. Most of the times, this after I go on vacation (airport x-ray machine or other rays from being on a plane)? And are always replaced under warranty.I seems to have this problem (on XP and Windows 7Pro), where as I load the card with my 40GB of 320kbps MP3 music, the load (write) speed slows, till goes soo slow, the computer times out and errors and complains the drive is no longer available.This time, this it did not crash. However it did slow to, 1/2 to 1/4 the normal speed near the end? However, it was over all 90%, faster than other cards I've ever used. Normally I have to separate the music in to groups, A-G, H-N, O-S.... etc. This takes most of an 8 hour day to do...This card though was fine (except the slowing down part)...

This works well in the phone an old computer illiterate person should probably not have. I can create more messes with that silly phone. But this card works very well in the phone. All that matters!

These are not the fastest Samsung Micro SD cards, but I have a lot of older samsung devices so these are awesome for them. You can't beat the price and I always try to match Samsung to Samsung although this isn't necessary I personally prefer it. Even though these aren't the fastest available most devices can't even take advantage of the speed of the newer models or pro models. My Samsung S7e and my new 8+ will have the pro version. These are great for backups and things like that. I sincerely hope it helps because there are a lot of choices out there.

Bought this for use with a Raspberry Pi 3. Works great. No issues. Was able to load all the games I have for RetroPie (over 500 games) and still have 12-14 GB space to spare. Formatted to FAT 32, copied image for 32 GB original card to new card then used gparted to resize partitions. Setup LibreELEC with 4 GB and gave the remaining space to Raspbian where I run RetroPie.

I don't know how fair this rating is. I bought this so that I could use the Android 6.0 Marshmallow feature of unifying with my internal memory. Samsung, the manufacturer of the phone and memory, disabled the feature and told me if I re-enable it (NOT requiring rooting my phone), it would void my warranty, as though I rooted it. Memory is slower than the internal memory but seems to be working fine, but Samsung's policy is why the three stars.
