Customer Ratings & Reviews

I've have this sd card for a few months. It worked great.....until last week. Now, it gets corrupted every day or two and needs to be formatted in order to get it working. Not much point in having it if it needs to be formatted on a near daily basis.

I ended up returning this item because it did not work well with my Surface. Would constantly disconnect. It may work great with a different OS but my experience was not good.

I thought I was buying the fastest memory card at up for this phone but to my dismay it is not fast at all I have bought the same from China due less than half the price

I bought these chips to use in a portable high-definition audio player. These devices require very fast read speed so you don't suffer stuttering in the audio when playing back 24 bit 192 KHz audio files. These cards did the trick and perform flawlessly. I had also received fake 128GB MicroSD cards from eB** sellers and want you to know that these Samsung cards are the real deal. You get what you pay for and the Samsung MicroSD's perform well. Highly recommended!

Real review, unlike many touted reviews on this site. Purchased on sale (under 45 dollars with free expedited shipping) and upon testing there were no corrupt files. 120gb of available space. Copied over 40gb of picture and video files to the card. Both read/write speeds were good and around specs when tested in smartphone. When copying files to the card using a usb 3.0 adapter the write speed was consistently around 15 mb.

I bought this 128GB micro sd to expand my cell external memory, my surprise was after I installed I found out that the real capacity is 119GB

had to get this memory card because the one that was being gifted with the phone was no longer avalible

I was presented with a list of gifts requested as a wish list from a relative. I have no experience with the item purchased.

I purchased this for my new Surface Pro 4 and it performs extremely well. It is rated class 10 and plays movie files without any hickups. As this was on sale at Best Buy, i also tried it in my Samsung Tab S... looks like i'm going to own another card very soon!

Got this cheap memory card at very low price so far good

I personally went to store and ask for my samsung note 4.. Best buy people didn't give me proper guideline that note 4 has only 64 gb expanded capacity. While I go and try to returned this item, the manger behaved very rudely and not giving my money.. nOw i have to fight with them..

I received my memory card broken, I tried to get it to work on several different computers that I own, and after no success I had the IT department at my work try and get it to work, and they said it fails to work on Linux, IOS, and all versions of windows they tried it on.

Great way to expand the storage on your MacBook Air or any portable device running low on storage. If you have a Nifty adapter its all easy. Just place the microSD into the adapter and you are good to go. Only caveats are 20 mb/s write speeds but if you are just storing bulk data like photos and movies that won't matter since read speeds go upto 80 mb/s.

Was getting a new phone and needed a memory card. Wanted a pro/plus version for write speed but expected to pay over $100...Saw this for $44 when I got so no way could pass up. Writes very pass when taking photos, copying music to it etc. Very nice!

I had no idea when I purchased the 128 GB card that the Microsoft surface did not properly accept this card. Switched to a 64 card and it works fine.

This was a memory card with no memory. Couldn't copy anything to it. Properties showed 100 KB of memory with nothing on the card. Returned it.

Honestly, it worked fine while it last but malfunction twice on me. Kept corrupting. Recommend buying from a different brand.

I use this as extra storage on my Surface Pro 4. OneDrive maps to it. No issues with speed.

the sd card was corrupted and destroyed my samsung tablet.

My recently purchased the Galaxy S7 Edge and had a 32 megabyte card in my last phone which was the Galaxy Note and I was reading the reviews on the 07 Edge to where it holds up to 200 gigabyte SD card so I started my search for a larger SD card and came across this Micro 128 gigabyte SD card. I figured a hundred twenty-eight gigabyte well big enough for my needs all I do is just put movies and music on my phone and I have yet to use all of the space that I have and it doesn't look like that I'm going to use all the space that I have. I would highly recommend this SD card to anyone looking for a larger SD card it runs smooth with no issues or any problems. I hope this review has been helpful to anyone looking to purchase a new SD card.
