    Failed after two months!
    After about two months of use, this card failed became read/only and would disconnect from the system randomly. Even connected through a USB reader, as opposed to the built-in microSD card slot I have the same issue. The system reports it as write-protected. If I leave it connected, it will prompt me every few minutes that the disk has errors and needs fixed. When reading data from the drive, it will disconnect then reconnect. I realize these have a limited lifespan - but two months at only 50% capacity is very disappointing.

    Great speed and works without issues.
    It is faster than Sandisk ultra micro SD 200GB which i had to return due to issues (i could not even play H265 videos without motion picture defects due to low speed, sometimes after sleep card was disconnected (windows 8.1 pro)).
    With his lexar 633x 200GB card no above issues, it is even faster than my previously used lexar 633x 128GB (same product line). I am using card for additional disk space with Surface pro 3 & windows 8.1 pro.
    Just the attached USB/micro SD adapter is getting very hot (same situation with USB port on Surface pro 3 and USB hub, just on Surface the temperature was little bit lower) and even can burn your fingers and mainly your device. I rather not use it and bought another USB/micro SD (warm but not extremely hot).

    5.0 out of 5 stars pretty fast
    Reviewed in the United States on September 13, 2016
    Verified Purchase
    I didn't run benchmark software, but just eyeballing it, it looks like the sequential write speed is at least 20 megabyte/sec. Could be 30, not sure. So performance is as good or almost as good as a U3 card. This was done using a baseqi adapter in the sdcard slot on a 2014 macbook.

    I haven't filled the card up yet, but I will. I pray that I don't get the early write protect error. This card was 4.5 stars when I bought it, but now it is 3 star, with many people complaining about an early write protect (basically their card failed, and that is only supposed to happen after many hundreds of writes to the same part of the card.) The card has a limited lifetime warranty, whatever that means, but the main problem there is the huge hassle with having to return it, and downtime, and Lexar gets all your data.

    1.0 out of 5 stars Copy a file with errors will get you a MICRO BRICK - Write-Protected forever...
    Reviewed in the United States on June 6, 2016
    Verified Purchase
    I posted this comment below to a reviewer. I would be happy to change this back to 5 stars if Lexar takes care of this issue. It's a nice card and VERY fast. However, when copying files to this card, at some point when copying over a file with errors, this card will switch into a permanent Write-Protection mode that is irreversible.

    If it were one card I would simply chalk it up to a defective card, no worries, you're always going to have that now and then but I have seen the same exact thing twice. Of course Amazon takes care of their customers and will let us return these things without question but it's a pain. I had this happen to my first 200GB card a week ago. I'm copying thousands of FLAC audio files to it....then at some point, I'm no longer able to copy (using the Lexar USB 3.0 dongle) as the disk is now write-protected.

    I've tried everything on the internet I could find. This thing is un-lockable. Side note: It's infuriating to have newbs chime in on how I should move the switch on my SD card to the un-locked position. Seriously. It's a MICRO SD card!! There is no switch!! Freeking newbs. OK, had to vent there, moving on...

    I bought two for my new audio player that has two slots for these. So I filed an exchange with Amazon for the first one - all good. Now I went about copying the same thousands of files to this new card....same deal!!! This gives credence to what the Lexar people have told other reviewers - that there is some bug with regard to write errors. I might have an erroneous file in my collection of files and this might be where it's bombing out. The frustrating part is that it's irreversible! Now I've got another MICRO BRICK. I'l try the first replacement that Amazon sends me but I'm fully expecting this to happen again.

    We shouldn't have to tread these cards like delicate flowers. Ironically, the data being copied to it is from a portable mSATA drive, which has no issues with files with errors. These cards should be error tolerant for sure. I'm a software developer and extreme computer user. I've tried diskpart, registry tweaks and a dozen other things. I can't figure out how to remove the write-protection flag. I think it's somehow a permanent glitch in the firmware of these cards.

    It works perfectly in my BlackBerry Priv. I went ahead with the advice of others and decided to throw away the included sd card reader. It's a bit too early to see how the card will perform long-term, but after about two days it seems to be doing exactly what I needed!

    Update: Still working well over a month later. I suspect the problems people are having may be related to using the included SD card reader. Just using it through my phone, I've experienced no problems.

    This works well in my GoPro Hero 5 Black. It can store almost 9 hours of video in the mode I selected. That's about 4 times as long as the life of a GoPro battery, so I have plenty of storage.

    I just received this card. After formatting it with FAT32, I put it in my Blackvue 650GW-2CH dashcam and it worked without any problems. I have yet to find anyone that confirmed this worked in the Blackvue, so I am confirming it does, in fact, work just fine after being formatted properly (FAT32, not exFAT or NTFS).

    For the price, you can't beat the capacity. I will update this review if the card fails quickly or fails to perform as expected over time.
