SanDisk Extreme 32GB MicroSDHC UHS-1 Flash Memory Card Speed Up To 45MB/s With Adapter- SDSDQXL-032G-G46A [Old Version]

I've purchased 5 of these at various times over the past year. 2 are used in smart phones, 1 in a digital camera, and 2 in tablets. The speeds are as stated, and they have performed flawlessly.I own various other capacity cards of the SanDisk brand that I use in my other electronic toys.....I had one problem with 1 card becoming corrupt about a year ago. I tried to reformat it with no success. One call to SanDisk, and they replaced the card within 6 days (after a few questions and another reformat try).I can't say the same about other brands of cards. Over the past 4 years (or so), I've had 6 of them "go bad" for 1 reason or another. Customer service on these "cheaper brands" was poor at best, and nonexistent at worst. I've stuck with SanDisk for the past 18 months with excellent success, and found that I get what I pay for. Nothing but SD for me in the future because of their dependability, and great customer support (when and if needed).Between my wife, grandson, and I, we have 13 devices that use flash memory cards, and only 1 non-SanDisk brand is still working and remains in the device (an 8gb Samsung).

We purchased this micro SD card to go with the GoPro we bought right before going on a cruise trip. We also have a stack of full size SanDisk SD cards for our DLSR cameras so we knew from the beginning that this is a good card. Upon real life usage out in the sea and entirely different elevation all videos and photos were recorded without glitch or lag. And of course, having had the 32 GB model, it was actually hard to fill it all the way. When we got back home from vacation, the upload speed was equally impressive. 20 gb of video and photos were uploaded on the hard drive in about 60 seconds. I remember when memory cards were astronomically expensive back 10 years ago and now technology has made it so much cheaper. We loved this card so much we got 2 more for our android phones.

SanDisk is about the only memory company that has legitimate advertising. I'm amazed, How does a MicroSD beat a regular SD?? ... I bought this with the intention of using it with a Wifi Adapter of questionable Chinese origin... That'll have to wait for Update #1. Anyway, it's better than the SD I was already using. So, why not, it works in my camera or my phone.DRIVE Read Speed / Write Speed (Mb/s)-------------------------------------------------------Sandisk Extreme 32 Gb Class 10 SD HC1, - 44 / 36Sandisk Exterme 32 Gb Micro SD HC1 - 45 / 40FYI, don't by SONY SD cards (they're cheap for a reason)Sony 32Gb Class 10, 69 / 18 ---Sony drive write speed is NOT Class 10Sony 64Gb Class 10, 46 / 15

Super fast storage. I use this card exclusively for my Galaxy S3 (Virgin mobile; see my other reviews for this one) and it works great. I have my photos save directly to it and storage movies on it as well. It keeps my internal memory free for all those "great apps" I have...lol.It comes with an adapter for converting to a standard size SD card so that is handy if I ever want to pull out the card to transfer onto my macbook.No complaints here, buy it now. Got a good price on it too.

I've purchased many of these and the 64GB variety as well. I'm using them in high-end high-resolution video surveillance cameras. I've had one fail and the replacement process seems to have gone very well (too soon to actually have the replacement, but the RMA process was fairly painless and only required a couple of responses to support's questions.

I have had 2 of these go bad on me when I used it with my Samsung tablet to the point that I couldn't even reformat them. For other applications, it works just fine (from GoPros to just using it as a thumb drive and as well as cell phones). Maybe I had a bad batch of them

I bought it for my GoPro about 2 1/2 YEARS ago. Ive used it in 3 different GoPros. Its been to 9 different countries on 3 continents, gets xrayed in customs all the time and I don't baby my camera at all. Never had a problem with it what soever!

Got this because I wanted high quality storage for our camera pictures to take on vacations. I have a SD Card adaptor so got the micro SD so I could throw it in my phone when it wasn't being used in the cameras. Got this over 2 years ago and still works perfect!

I bought this because an earlier 10-class card by Samsung was producing poor results in combination with a GoPro Camera. I'd heard the Sandisk Extreme series were more reliable, so took the plunge and bought one.I was pleasantly surprised to find the quality of the Sandisk far outmatched the Samsung. Whereas the Samsung would lead to recordings being cut-off midway, the SanDisk had no such issues with the same camera. This would suggest that not all class-10 cards are equal.Does this matter to you if you don't have a GoPro camera? It depends. If you're just using your card to store files such as in an e-reader, it shouldn't matter too much. The speed rating is about the same. The difference is that the SanDisk produces reliable streaming of recording and playback, which means with anything that requires a constant stream of data to be recorded out (audio and video recording, for example), the SanDisk Extreme will have the edge of other competing products. So if you use a video camera or audio device, you'll the find the SanDisk the better bet.The pricing is expensive, but its not extraordinary when compared to the competition (and of course the technology is stunning.) Recommended - but only for people who need the reliability. For those who are just recording out files there are cheaper options out there.

I invested in one of these for my GoPro 3+ Black Edition and so far the testing has been pretty good.I used an app called H2testw (google it) for testing the read and write speeds on my PC and these are below.As its rated for up to 45MB/s I cant really complain at 43!However, please note that using the SD Adapter card, you need to make sure it's USB 3.0 compatible reader, plugged into your USB 3.0 port otherwise it will max out at USB 2.0 speeds (approx 30MB/s).It will of course write at USB 3.0 speeds when in you GoPro 3+ however bottle neck will be copying back to your device for editing/review afterwards. But if these speeds are anyway near what I achieve in the GoPro3+ then I'll be very happy!!***I TESTED BY WRITING 2.00 GB INSTEAD OF WAITING 15MINS FOR 32GB***Warning: Only 2000 of 30538 MByte tested.Test finished without errors.You can now delete the test files *.h2w or verify them again.Writing speed: 43.0 MByte/sReading speed: 73.5 MByte/sH2testw v1.4

Made a noticeable difference in my SONY NEX-5.I'd had a previous Micro SD card in my camera and I noticed that when I would take continuous shots for actions after the camera had banged out a dozen shots then I had to wait several seconds as the camera wrote the data to the card. You get used to the time period this takes.When I put this in I had a noticeable improvement in the time I had to wait before the camera came back on line and was ready to take more pictures. So most definitely it is an improvement on many other SD cards I have used over the years.

Purtroppo devo dare un giudizio molto negativo perché a causa del malfunzionamento della micro SIM ho perso un sacco di video fatti e tantissime foto.Quando andavo o a scaricare sull'App. O sull'Ipad non riuscivo a visualizzare nulla e lo stesso mi accadeva sulla Gopro 4 silver con il retro camera a video.È stato dopo molti tentativi aiutato dallo staff tecnico di Gopro support che ci siamo accorti essere la SIM la causa di tutto e così ho dovuto comprare un'altra micro SIM e adesso tutto funziona alla meraviglia,l'unico problema è che ero e sono tutt'ora in Indonesia e ho perso tutti i filmati fatti in questi magnifici posti.Ora a distanza di tempo non penso sia possibile essere rimborsati,comunque il problema è che quello che pensavo aver registrato o fotografato è andato perso.

I ordered this after I got a GoPro Hero3+ Black Edition as a gift, and found that the microsd card I already had simply could not keep up with the data transfer rate the camera needed for the full hd (4K) video. GoPro recommended a Class 10 card, such as this SanDisk Extreme. My GoPro doesn't even bat an eyelid now. And transferring the massive files from the card onto my computer via my card read and using the microsd adapter that comes with the card is lightning fast. I'll no loner have to wait for minutes on end whilst the large files are transferred via USB. Very impressed and a must buy for anyone with a GoPro or other digital device that requires high bandwidth data transfers.
