Fits the nintendo switch one of my games is downloading on it I will give an update on how it plays but so far so good package came undamaged looks great

By Grace Laycock on 8 January 2021
Fits the nintendo switch one of my games is downloading on it I will give an update on how it plays but so far so good package came undamaged looks great

I've ALWAYS purchased SanDisk cards as they have been super-reliable and used them in phones, tablets, security cameras, dashcams, action cams and Raspberry Pis.
When I purchased this SanDisk Ultra, I noticed the sudden flimsy feel of the plastic used. So much so, one actually snapped when inserting it into a Raspberry Pi (and I wasn't being a gorilla with it - the plastic is really soft). Amazon thankfully replaced it with another one (Thanks A!).
The replacement came and I decided to put it into my GoPro 9. All was good until I came to record video - it would stutter and even give corrupted recordings. Not good.
I plugged it into my card reader and now the computer isn't reading the card. When I took it out of the card reader, the card was VERY hot. Not "fry an egg" hot, but i've not felt it be that hot before.
I tried another card reader - same. Unable to read the drive. Device Manager won't let me manage it - Disc Error... so it wasn't a case the drive needed re-building.
Again, Amazon agreed to refund me this card now - so i'll buy another Lexar High Performance 633x card - which hasn't had these issues!
For me I can take a burst shot of photos and they should save in a few seconds.
I am also keen on photography and need to do this as part of my job also, where also SD cards are important, and also select Sandisk SD cards here as well.
With all this technology in my life, I also often need USB memory sticks (USB Drives) and also use Sandisk there also.
At this point you probably think I have shares in Sandisk! But no, I am just someone who has been burned by cheap SD and Micro SD cards in heavy duty environments where they really do get a pounding, with some other brands only lasting a few weeks, whereas some of my Sandisk SD and MicroSD cards are now several years old and still working fine, so I felt the need tonight to give them the credit they are due.
Well done Sandisk!
Phone recognised it straight away proceeded in moving everything from old card to this and all worked as it should added more music files no problems.
All of a sudden then phone started saying problem with card (need to format) moved all files onto computer then formatted and ok for a while then phone started saying the same thing again?
Plugged into pc used chkdsk etc which said corruption was found and then cleared but phone continued to say the same thing??
Sent back and purchased a Samsung card instead loaded with the same files and touch wood everything ok so far! So have no idea what was the matter with the SanDisk?
The Micro SD Card looked totally authentic, even down to the packaging itself. It's when I inserted the Micro SD Card into my Nintendo Switch and started downloading my on-line game collection things started going wrong. What was supposed to be a 256MB Card started to error out after 60GB of downloaded game data. After an investigation on my PC, it turned out the card is fake. Closer inspection and internet search and the tiny numbers on the back of the card didn't match up to how a real card looks like. Checking on-line real vs fake was the only way to find out the card isn't faulty, it's 100% fake.
