1 out of 5 eggs

This review is from: SAMSUNG Pro 64GB microSDXC Flash Card Model MB-MGCGB/AM

Pros: The card worked great in my Samsung Galaxy S4 after having trouble with a Sandisk card. I bought a Samsung card to use in my Samsung phone thinking there should be no compatibility issues.

Cons: After 6 months of trouble free use, the card suddenly refused to write any data. My data was retrievable, I just couldn't write to it. I tried formatting it in various card readers, mp3 players and phones, including using Linux and dd to try and wipe it. No go.

Contacted Samsung as product is advertised as having a 5 year warranty and was informed that MicroSD cards do not have any warranty and I would be required to purchase my own replacement or go back to Newegg for a replacement.

5 out of 5 eggsThis is the one you're looking for!

This review is from: SAMSUNG Pro 64GB microSDXC Flash Card Model MB-MGCGB/AM

Pros: Flawless operation out of the package, no errors or hiccups

Cons: None so far... Perhaps the price point (but it's well worth it!)

Other Thoughts: I have this paired with my Motorola Razr M phone, and I had first purchased a Sandisk 64GB Ultra... I constantly (and at the worst possible times) would get the "SD Card Unexpectedly Removed" error... seemingly whenever it wanted to, it would simply stop accessing or noticing the card. (Sandisk is a decent brand, but apparently some of the early revisions of the cards have compatibility issues). I've seen that Samsung phone users have similar issues with 64GB+ cards...

I saw several reviews of these Samsung microSD cards, and I figured that at least I would know if it was the card that was my problem, or the phone (I'm due for a phone upgrade anyway). Sure enough, it was the card!

I simply popped in the Samsung microSD card, let the phone format it, copied files to it with my PC's card reader. Done. I've been using it for a couple of weeks now, and not once have I had an error, or the "SD Unexpectedly Removed" issue. It simply works, and seems to read/write quickly to boot.

Before the switch to this card, it would happen about once a day, or more. My phone is now useful to me again!

If you have a device that does support the 64GB cards, but are having the same issues, you might want to consider that it's the card, and thy this one.

5 out of 5 eggsBest 64gb MicroSD

This review is from: SAMSUNG Pro 64GB microSDXC Flash Card Model MB-MGCGB/AM

Pros: Speeds are definitely higher than any of the other comparable micro SDXC's. I bought this for my phone and ended up putting it in my Go Pro because the SanDisk 64gb I had couldn't handle the speed of the Go Pro. SanDisk would stop recording after 17 minutes every single time due to dropping below required SD speeds. No issues using the Samsung.

Cons: Price is still higher than all the other Micro SDXC's.

Other Thoughts: Will be picking up more once I see price deals pop up. Cant beat Samsung for micro SD or SSD's when it comes to quality and speed!

This review is from: SAMSUNG Pro 64GB microSDXC Flash Card Model MB-MGCGB/AM

Pros: 64GB

Cons: 64GB doesn't help if it doesn't last more than 6 months. Cannot seem to find the way to get use of the 1 year or 5 year warranty

5 out of 5 eggsh*ly grail of GoPro3 Black memory cards

This review is from: SAMSUNG Pro 64GB microSDXC Flash Card Model MB-MGCGB/AM

Pros: -fast transfer speeds
-when used with a USB 3 card reader that's plugged into a USB 3 port, you will enjoy fast file transfers
-ideal card for buggy, issue-prone GoPro3 Black camera

Cons: none

Other Thoughts: GoPro3 Black is quite famous for having/creating memory card issues. It even ruins them. But this card solves all that. Any other trouble you encounter can probably be blamed on your GoPro, not the nice Samsung memory card.
Have you ever had your GoPro card go "corrupt", with all the irreplaceable GoPro files on it becoming suddenly unreadable?
Here's how to solve the dreaded "you must format this card before using it" message that often pops up when you plug your loaded GoPro3 card into your PC and it refuse to read it.
Don't worry, your files are still on the card! So by all means don't reformat it!
Do you know how to access the run command on your PC?
It's available on the Start menu. Or if it's not seen there just type "run" in the Start Menu's little search box and it should be the first answer returned at the very top of the list.
Click on it to open the "Run" command.
Now type "cmd" (for "command") and click "OK".
That will open the command prompt.
Now, before you can really begin fixing things, you must determine which drive letter your PC has assigned to your GoPro3 card. For this quick tutorial, let's assume the drive letter of the GoPro card is "E". In actuality, it might be a different letter for you. But we'll use "E" in this example.
1. To simply "check" the card for errors, type this into the run command line, exactly as written below:
chkdsk E:
2. now hit "Enter"
3. Now your PC quickly checks the card for errors, and shows you the results.
--But this next step takes care of the whole deal in one move.--
4. To check "AND fix" the errors in one simple step, type this into the run command line, exactly as written below:
chkdsk /f E:
5. Click "Enter"
6. You're done.
That should fix all the card's errors, and make your valuable GoPro recordings accessible again!
The GoPro is to blame for messing things up, and making it so the card cannot be read by your PC. But the recordings themselves are not affected. This fix repairs what's wrong, and solves the problem.
Once fixed, the computer should instantly discover the newly corrected card, and an auto-play dialog box should appear!
Problem solved.
Again, just be sure that you use the correct drive letter of your GoPro card. The example we used was "E", but your drive letter may be different. So just replace the "E" with correct letter.
If you use this quality Samsung card in Your GoPro, the above fix should work every time. Other cards can get toasted by a GoPro, or so I've very often read. Even the exact brand and model of flash card GoPro recommends and sells on their website, gets easily toasted (ruined) by a GoPro.
...whereas this Samsung seems to be bullet-proof.
This card has eliminated all my GoPro3 Black issues, because it's always instantly recoverable, by following the simple step(s) I've outlined above.
Hope this helps someone.
Bottom line? Great card.
