Made for Amazon SanDisk 512GB microSD Memory Card for Fire Tablets and Fire -TV

I ordered this SD card yesterday and got it today the shipping was extremely fast! At first I was unsure of how to install it but it’s pretty self explanatory.. I charged my son’s tablet all day and then turned it off, installed the card, powered it back on and once I unlocked it the tablet pretty much guided me through all of it! I did have to go to the storage setting on my profile and push transfer apps to card but it also told me to do it after it formatted so I didn’t have to figure it out or anything like that! I purchased the 128 GB card for my son’s fire tablet and I’m impressed with how much space he has now! He’s downloaded like 10 apps and he still has tons of space! For what I paid it was definitely worth every penny! If I ever need another I will for sure be purchasing this brand again! Works perfectly for us!

Easy to install, easy to use, decent price, good product, very sturdy. I love it 😍👍❤️😄 good recommend for everyone. Thank you Amazon

Only two weeks in, but the memory card seems to working great.I got this card for my kindle as it was specifically recommended by Amazon, and my kindle came with only 8 gigabytes of storage, which is ridiculously insufficient for any modern complex operating system expected to accumulate data. Even worse, it's not really 8 full gigabytes. (Also, I got tired of being nagged about running out of space after taking only a few dozen photos.)Computers like numbers that are in powers of 2, and work best with processors and RAM that are built on powers of 2, which is why you usually see numbers like 8, 16, 32, etc. and not "strange" numbers like 10, 21, 43, etc. For this reason computer systems have *traditionally* used 1024 (2^10) as a base when reporting storage usage in kilobytes, megabytes, gigabytes, etc.When it comes to a physical storage medium, however, capacity does not have to be a power of 2; it can be whatever number of storage positions will *physically fit*, the only real requirement being that the computer processor can count that high.Manufacturers are notorious for cutting corners in manufacturing wherever possible then hyping up their products. In the case of the kindle, Amazon used 1000 (10^3) as the base of its "8 gigabyte" claim and aimed for a physical arrangement that would guarantee *at least* 8,000,000,000 bytes of storage (1000*1000*1000*8), over half a billion bytes short of 8,589,934,592 (1024*1024*1024*8). Not surprisingly, SanDisk did the same thing with this less-than-32-gigabyte memory card, as this deceptive practice has become an industry standard. But I digress a bit, my point being that an 8-gigabyte kindle affords you with MUCH less storage space than you would expect, necessitating a memory card for expanded storage, especially since the kindle's operating system uses a LOT of overhead, and every application you install also wants to use a lot of storage.When inserting your new memory card (or removing it) it is best to do so while the device is turned off. Mobile devices are finicky when it comes to "hot swapping" memory cards, often refusing to read the card, or even worse, damaging the card and corrupting data.After you've inserted the card and turned the kindle back on, go to Settings -> Storage, and move all the option sliders to the right to tell your kindle to utilize the memory card as much as it is willing to. Unfortunately, some features will still waste space on the internal storage, e.g. screen captures and blue tooth file transfers will NOT be saved to the memory card.To "move" my kindle books to the memory card, the easiest way was to delete them then re-download them. To move other personal files to the memory card, I connected my kindle to my PC and used Windows Explorer.From the previously mentioned settings menu, you can also move *some* applications to the memory card. Before and after the move, the amount of storage used on each disk is displayed. Moved applications will still use *some* space on the internal storage, and funnily enough, moved applications use more TOTAL storage than when they resided solely on the internal storage.One application I did NOT move was ES File Explorer, as this is a system-critical application (due to the kindle's shortcomings).It should also be noted that the kindle's crappy built-in file browser CANNOT locate the memory card. The files *are* there, but you will NOT find them without a proper file browser like ES File Explorer. Also, some programs (such as the red Notepad) will not be allowed write permissions to the memory card!A few days ago my wife turned on my kindle and it updated itself which took over half an hour, which seemed unusual because when I observe updates they tend to run much faster. Afterward, my kindle stopped recognizing the presence of the memory card. The solution was to turn off the kindle, remove the card, turn the kindle on, then back off, then reinsert the memory card, then turn the kindle back on.The card is working great, and is less than 3% full while my kindle has less than 1.5 gigabytes free.Update 2018-04-23Last night just before I went to bed, my kindle battery was running low. I was too lazy to go find a charging cable, so I just turned the kindle off.This morning I turned it back on, with only 12% battery power remaining, and found that several program icons were dark. When I tried to launch one of them, I was told that the program couldn't run because the memory card could not be found! I tried removing the memory card and restarted the kindle like I described in my original review, but the memory card could STILL not be found.I took the memory card out and connected it to my desktop computer and confirmed that it was in perfect working order. I then put it back in the kindle and connected the kindle to my computer, letting the charge process turn the kindle on. The darkened icons were still dark, and I saw a flash of the memory card icon at the top-left of the screen. I opened ES File Explorer which located the memory card and showed me its files. I went back to the home screen and none of the icons are dark any more.I guess my piece-of-crap kindle doesn't want to exert any effort accessing the memory card if the battery power is red-lining when the device boots up.

Normally, I've never had difficulty with SanDisk products, especially since I have a microSD in my New Nintendo 3DS XL, but I have been hearing the difficulty some have had with the product when it comes to storing personal videos and photos. For some reason, when you turn the Kindle Fire off (as opposed to just placing it in stand-by mode), then turn it back on, the Amazon Storage SD system will apparently move your downloaded photos and videos into the Others file for some reason.Meaning the files haven't technically been removed as you might suppose (since the SD Storage will still acknowledge the memory is still there), but it does make it become rather inaccessible from the Kindle. Technically when I connect to my computer to locate the files I'm not sure how to find them, or even if i can move them back to the appropriate spot.Overall, the result is usually having you to reformat (aka erase the card), then putting back your personal items on it via backup. Which for me is not really a pain, but having to reinstall apps and restore Amazon Books and Films back on the card can be tedious. So you're probably saying, 'Well, don't turn off the Kindle then.' Consequently, this can be difficult though when you have to do a power reset, like, say you're Yahoo Account is having problems, or you accidentally let your Kindle decharge completely.I'm wondering if the problem does not lie so much with the memory card, since it hasn't actually popped out my files or reshuffled them to Others unless you shut down the tablet completely. But instead possibly something with the Amazon OS which somehow either transfers the files or just makes them inaccessible upon powering up.Overlooking this obstacle, the SanDisk Ultra is a pretty good microSD Card for what it's worth. Hopefully Amazon, or SanDisk themselves, can look into this problem and can rectify it with an upgrade or a way where the card is formatted with the appropriate files you can use to place your photos and videos onto it.As for the book issue, the SD Setting menu claims it will allow books to be saved to the card, however, as with the RiffTrax downloads, the Comixology books will not download to the card for some reason. Perhaps I suspect this is due to the fact these are Third Party services (despite Comixology being part of Amazon) and it defaults to the device storage instead. Still working on it to see if there is a way at least for Comixology books to be saved to the card.I've heard on the lower reviews that they've gotten a PNY 128GB MicroSD, and plan on getting one just to see if the issue is either really with the cards themselves or the Kindle. So far the card storage system works for what it's worth, but like I said, until they can find a way to fix the issue of it shoving the personal files into the Others, I can see this becoming rather annoying fast. My only current suggestion is, to create backup files of your stuff in a separate 'Kindle' file on your computer and just transfer it back onto the card whenever it does this (after erasing it). Hopefully I'll let you know in an update how the other brand works and if it suffers from the same issue.UPDATE: Adding a star because I did solve the Amazon memory issue. Basically I discovered that I was writing folders onto the card through PC. But here's why it went wrong, by doing this the FireOS will not recognize the folders as part of its storage system.In short, when you power down your Kindle, it will automatically dump your personal folders and data into the dreaded OTHERS file. So here's what you have to do to prevent this glitch:Connect your Kindle to the PC (via USB cable/charger). Go to the Kindle icon in the Folders Menu, then into Internal Storage (aka Kindle Hard Drive). Locate the Folders marked Downloads, Movies and Pictures. COPY (don't MOVE) and PASTE these folders into the External Storage (i.e. microSD card). By doing this you will have formatted your card where the FireOS will acknowledge the folders and the contents as part of the Amazon storage. So if your Kindle does accidentally power down, it won't dump your personal stuff into the Others file, making them inaccessible to your Kindle.However, this isn't foolproof but after doing some tests after the above procedure, I so far haven't lost my personal videos and photos on the card.Hope this might help you out.

When I put the sd card in it said it was corrupted. I searched and searched for a solution to fix the problem. I finally found an article on REDDIT that said make sure you are signed in on Your parent account and then it will let you install in. When I signed on as me, I was able to install the card, and it started working correctly. I hope this helps someone else to not waste so much time trying to figure this out.

So far, so good!

Best storage for the price. Just slid right into tablet. Very functional when you don't want a monthly cloud payment.
