Performance and price are not proportional when it comes to selecting a microSD card. Some of the worst performing cards in this review also happen to be the most expensive.
Not all 633x cards are created equal. The two cards reviewed from Lexar and Transcend are both marked as 633x but vary in performance greatly.
4k video recording using action cams and drone cameras have a typical bitrate of 60mbps or 100mbps, corresponding to 7.5MB/s to 12.5MB/s. All cards in this review should theoretically be able to handle this usage easily.
Using microsd card as supplemental phone storage potentially could benefit from a faster card,
Best Looking Card (if it matters):

Lexar 1000x: White/Gold with Black/White print
Samsung Pro+: White/Black with a red stripe and Black/White print

There's one more huge benefit in using these Lexar High-Performanc: the color! Almost all other microSDs are black or dark blue so there easy to lose if they are anywhere with a bunch of black equipment (every single accessory and removable piece of the GoPro is black plastic.) These, on the other hand, are always easy to see and locate. Even when it's mounted in the GoPro it's the bright two tone blue and black end is visible so you can tell that there's a card loaded in the camera just by glancing at it. It's the little things that make life easier...

I purchased this Lexar microSD (128GB) card to be used in my brand new Droid Turbo 2 phone. I've been quite busy the last couple of days transferring 5,331 songs, tons of digital photos and somewhere around 30 hours of video onto this card from my PC. Ended up being about 80GB worth of data when all was said and done. In an attempt to quicken these transfers, most of them were done using the USB 3.0 reader included with this card. Everything seemed to be working just fine although I was a bit concerned with how hot this card got during large transfers; but it wasn't anything that I considered 'out of the ordinary' as that's to be expected with high-speed flash memory. After returning the card to my phone, everything looked good. The phone registered this card as 119GB of total space and all of the data I transferred was found and accessible.
It was earlier today, as I was laboriously working at correctly categorizing the tons of songs I transferred, when my phone just hung for about 30 seconds or so. When I finally got it to respond again, I noticed that the microSD card appeared to be missing. When I went to the storage settings menu, all it said was that my card was unmounted and could safely be removed. The "Mount SD card" button was ghosted out although the "Erase SD card" button appear to be functional. At this point, I did a hard re-boot of my phone and it powered up with a microSD image displayed on the top display bar that had a message about the card being unmounted and removable. The storage settings were the same as before the reboot.
I then powered the phone down, removed the card and tried to look at it on my PC (using both the included USB 3.0 reader as well as a micoSD-to-SD adapter I had laying around). Interestingly enough, I was able to see the data. More interestingly is that my PC was showing the microSD card as being write-protected. This is interesting in the fact that, unlike a standard SD card, there is no physical way to write-protect a microSD card. My PC, however, was reporting the card as being write protected. The good news is that I was able to copy the data from this "write-protected" card to a folder I created on my PC. The bad news is that I was unable to re-format this microSD card. I initially attempted to format it with the phone, but that didn't work; so I then tried to format it with my PC but my PC said it couldn't be formatted because it was write protected.
So basically what I am stuck with now is a write protected microSD card that can only be read by my PC and is completely un-mountable in the device (my phone) that I bought it for!!! I'm not a happy camper...
Suffice it to say that I have already initiated the exchange procedure here on Amazon. My replacement card is currently scheduled to be arriving between Nov 30 and Dec 3. I'm hoping that I was just unlucky and received a bad card last time although you can rest assured that I will update this review accordingly.
Received my replacement card today. Spent the last few days creating a 112GB "image" on my PC containing all the photo, music and video that I wanted to put on my phone. I did a bit more research into these SD cards after having the experience I originally reported for this card (above) and discovered that what actually happened with my first microSD card was most likely a "feature" as opposed to a "bug." Well, a feature launched because of a bug... What these cards do is automatically put the card into an irreversible "write-protect" mode when a write error is detected. The logic being that by making the card read-only, the user can retrieve any data that had been transferred prior to the error; and, since the card no longer will accept writes, no data already on the card can be destroyed due to future write errors. It's basically a data protection technique. The problem with this is that the android operating system on my phone (Droid Turbo 2) refuses to mount a write-protected microSD card which basically makes the card useless for the phone. I as explained above, I needed to use my PC to get the data from the card after it had been set to read-only. Anyway, that's just some useful information to anybody using SD cards in general.
Now, that being said, I've learned that the best use for these cards is for storage of basically already finalized static media files. You don't want to be using SD cards for any purpose that's going to require excessive amounts of writing as each write has the potential for an error that could trigger the feature I just explained. So, that's how I'm using it this time. I finalized all of my media files on my PC prior to transferring the rather large (again, it's 112GB) set of files to this microSD card in one shot. So far, everything's good as I have inserted the darn near full card into my phone and all the files are accessible (my Poweramp app just completed successfully scanning the 5726 songs that I transferred).
Now one difference that I did notice with this replacement card compared to the first card I received is that it didn't get nearly as hot as the old card got during the transfer. I find this interesting as it might point out that my old card was actually defective in some way. The old card got quite hot during data transfers whereas I hardly notice any heat from this replacement card even after dropping 112GB on it at one shot. And the transfer was done using the high-speed USB 3.0 adapter ... still I hardly noticed much of a temperature increase.
I have therefore updated my rating to 4 stars instead of the 1 star I initially reported. I would've given it 5, but my initial experience cost it one...
