That explained, I tested my card's speed to see if it hits the 120MB/s ideal... not really. But marketing hype being what it is, I'm sure the "Speed up to 120/MB/s**" is in perfectly ideal conditions with specific readers and file sizes and the like... so my test of 93MB/s on a 10 year old USB 3 card reader with the SD adapter is acceptable to me. I think this should work fine on a soon to arrive Nintendo Switch for the kids. I'll update this review if any surprises come up that should be noted.

Is 1TB overkill for a Switch? Probably.
Should I have spent so much on a teensy piece of plastic? Eh.
Does it work? Yup, 100%.
Popped it in, re-downloaded my games, got back in the action. Highly recommended for anyone with a backlog that looks more like the inventory of a reputable, mid-sized game shop.

There are many disks on the market to choose from and there are also many fakes on the market that look genuine but are far from it - as I know to my cost - if it looks too cheap it's probably a fake.
I bought mine as a 'Dispatched from and sold by Amazon' which provides a level of surety regarding its heritage and a good price/delivery into the bargain.
I am pleased to report that this works perfectly for me and on that basis I am very happy to recommend this item to you.
Thank you for your time in reading my feedback/review – I hope it may have helped you in your buying decision.

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!
