It stores my stuff in my N4, I love the thing every body go out and buy one

Worked fine all up until the day before this review. Nothing out of norm when using it. Only stored tutorial and class videos as well as a few apps from playstore. Phone began to slow down, and all apps and videos on disk would not work, everything on phone storage would aside from tremendous slow time. Decided to wipe/reformat SD card, failed to reformat and went through a hard time trouble shooting all day. 2 Stars - 1 for each month it worked

I purchased this because I had run out of space on my old Samsung micro SDXC UHS-1 Card PRO 64GB Class 10 for Galaxy Note 2 II. That card had followed me from a Note II to a Note 3 to my current Note 4. I was a little concerned about compatibility and reliability because a few years ago tried to save a buck by getting a tier 2 brand card that literally melted down. This time I took a chance with this non-Samsung card and cannot be more pleased. For one thing, the transfer from my old card to this one did not cause this to get hot. Considering that there was about 29GB involved that was my first indication that this is a well made card. Another thing is after I transferred the contents to this card (via a card reader), as soon as I popped it into my Note 4, it immediately mounted and everything on the older card was there. I took the time to look for corrupted files, sampled a lot of random music, and checked a few videos. Zero issues and the Note 4 did not balk at this card or any of the files on it. As for speed, I am not going to make claims one way or the other. I did not test it with benchmarking software, and since I use this mainly for streaming music the additional speed (if any) is not noticeable anyway. What is noticeable is the total compatibility with my Note 4 and the extra breathing room the capacity provides me. Overall I am not only pleased, I feel as though this card is a better value than the Samsung brand cards that I had been purchasing. And every bit as reliable too.

The memory melted in my wife's MacBook Air. All the data was lost. Thankfully it was removable and didn't damage the computer. The card was purchased 11/16 so it was less than 7 months old. I had a SanDisk microSD card fail in my phone this year and our SanDisk Solid State hard drive has failed multiple times in our HP laptop at work. I'm done with SanDisk

Picked this up for a great price. I am using this on my Canon DLSR with the apadpter and it works flawlessly. Since I shoot in RAW, the large space is needed - as well as the fast read/write speed. This card can handle both. As for video, it can write 4K video, but the speed on this card is perhaps not optimized for these extremely large video files. It takes a little more time for UHD video capture. And with the adapter that comes with it, formatting on Windows, Mac is also simple. The card also works very well with my Samsung Tab A 8gb, quickly adding an extra 128gb to the tablet. Basically it can be used for anything like backing up 1000's of songs, documents, photos, etc. with absolute ease. It's a powerful handy little card.

This review is for the SanDisk - Ultra 128GB microSDXC Class 10 Memory Card - Gray/Red. My wife and I purchased a pair of these cards during the 2015 Black Friday advertised sale at $39.99 each. At this price the product is a ridiculously great value (with limited expectations). If speed is your only concern you should probably look at something else, as this is clearly not the fastest card on the market. If high capacity is what you seek, then this is for you. These cards come preformatted as exFat. Because of this, and strictly due to the limitations of our phones, the cards were not initially recognized. I was forced to reformat them as fat32. Note that Windows will only format these as NTFS or exFat, I had to use a third-party freeware utility to reformat to fat32 (in hindsight maybe I should have tried NTFS first). Also keep in mind that reformatting away from their native exFat will slow them even further. However, after reformatting they do function properly, and after a 5 hour copy process, our 90GB library of: 14,000+ songs, and 8500+ photos, is now entirely accessible on each of our phones, and we still have room to spare! Are you kidding me! On sale price + these cards have room to spare + fast enough to record photos and video from our phones. What's not to love! If it's on sale, go for it, you won't be disappointed!

Never worry whether you will run out of memory on your tablet or phone with this little beast. This is the second card I have purchased for myself. The first time I got it for 50% off the original price. The second time I purchased it it was about 60% off the original price. Pounce on this when you find it at your preferred price range! You can't go wrong with it. If you don't use in your phone or tablet, you can stick it back in the adapter and use it as a SD card for your camera(if it is compatible).

Not much to say but tons of space on this tiny card with great access speeds at a fantastic sale price! Just can't find a better deal on this size of card to use on a Nintendo Switch. It works beyond expectations and a huge savings over the licensed cards with the only difference being licensed for use on the switch in order to get people to overpay. Highly recommend this card with many different uses on phones, camera's, as well as gaming systems.

Great speed & capacity at affordable price, definitely better performance than my previous Samsung card

I have several SanDisk memory cards, but this is the first one that has a 128 gigabyte capacity. I am using it in my Samsung Galaxy J7 smartphone to store photos, videos and some apps. It has been working flawlessly with my phone, allowing me to access files quickly. My other SanDisk cards are in cameras (3), a GPS device, an old mp3 player, and a tablet. All the cards have been working flawlessly, some for several years. A great product!

I use this for my Moto Z3 to expand my memory, great for full HD and even greater price for a class10 card which I would recommend you use in any newer device. Speed,reliability,capacity,value all fall right in place with this card, great buy happy customer.

I give this product 5 stars because of its versatility. You can use it to on your phone, tablet or computer and it has a fairly fast in transfer speed although you have microsd cards at double the speed in the market now My reason for giving this 5 stars was the cost and reliability factor with san disk. I got the product a a good sale price and the 128 gb space is great. Over all a great product and a recommended buy.

I bought the memory card and when I pulled out it broke, so I was never able to even use it.

I flip-flopped on exactly what I wanted to acquire as additional storage on my new Samsung Galaxy S7 Edge, thinking 200 GB would be better than 128 GB, but couldn't for the life of me think of what I'd ever acquire to need that much space. The helpful staff at Best Buy offered good opinions as well. This one was on sale at Best Buy, and the larger card was on sale at a major online store. I chose this one, and have come nowhere near close to even filling up half of what it has to offer. Heck, I started giving it Thumbs Up when the packaging was so easy to open (no cuts from the plastic blister packaging - Yea!), and then that was followed by very easy installation into the card tray of the new phone. The recognition was instantaneous, and the settings quickly adjusted. Samsung restricted more than I anticipated the number of applications I could transfer and run from the micro SD card, but that is not an issue with the card. Those apps running from the card are just as responsive as those running on internal memory (as far as I can tell), so I'm super pleased with what this memory is providing in that regard. The transfer of audio (iTunes to Android) and also video (from PC to Android) was quick and easy, as the SanDisk card accepted everything rather briskly . . . and no errors in the process. Yep, I'd easily recommend this product to others, as well as do a repeat purchase myself if that situation ever arose.

This is the second SanDisk memory card I have. The first one is a 64 GB that I am using on another phone. It has worked fine for a couple years and when I wanted more space, I went with another SanDisk. I use mine for pictures and music. Holds lots of both.

Yup, does what it's supposed to. Holds lots of data, is fast, didn't need formatting on my Galaxy tab. Very good price. And when I was a boy this amount of storage would take a room the size of a warehouse. Go for it. SanDisk is very reputable.

GET. THIS. CARD. Ask yourself, what are the chances of you taking 16,000 photos? What are the chances you'll need to record 8 hours of video? Your answer? Probably NEVER, but, you'll be ready if you do! The speed, the quality, the ease of use, is absolutely splendid! I utilized this card in my GoPro Hero 4, I used it on a cruise my family took. I snapped roughly 3,000 photos and took about 3 hours of video, total; not all at once. I downloaded photos to share with family and friends, but decided to leave them on there for ease of access later. Fast forward to my next cruise, 5 months later, I never took the photos off of the card from the previous cruise and just rolled with it. This card took new photos and video like a champ, still with room to spare! I bought a 200GB with my initial purchase of this 128GB, not sure what I would need. This card surpassed the 200GB, being that it is rated for all things GoPro, Hero 4 and 5 (My brother had the Hero 5). I now have this card sitting in my Gear 360, taking the Photos and Videos from it. Excellent card, especially if you catch it on sale!

If you are looking for a micro sd card that you can put a TON of data on, that also has quick transfer speeds, look no further. I got this card at a rather awesome deal on black Friday for approximately $30! Can't hardly beat that!

Purchased to use for local storage on my Amazon Fire HD tablet. Allows me , more importantly my son, to watch media offline. Card is definitely fast enough for this purpose and has been working reliably for the past couple months.

Bought this on Black Friday, so it was an great deal on a large capacity SD card. It's very fast for a SD card. I use it in my Samsung Galaxy S7 for extra memory to store movies and music. Movie playback has been flawless.
