After I had data loss with a Sandisk -- till that point I never used anything but Sandisk -- later I found that the card reader was not up to its specification, I was searching for new cards.
Then I saw hundreds of posts on Amazon recommending the Samsung and hey, this is the real thing:
While other cards claim 90 MB/s -- which only means 90 MB max. read speed, the Samsung claims 90 MB/s read & 80 MB/s write and lives up to that task
I bought SDHC 32GB/64GB PRO UHS-I Grade 1 Class 10 up to 90MB/s read, up to 80MB/s write
You need a reader that is safe with UDMA7 and USB3 Interface though. After trying several I finally found this: Kingston Media Reader FCR-HS3 card reader USB 3.0.
I connected it with the long cable directly to the mothership.
Now I cannot cook a coffe while transferring 64GB to the computer anymore.

Frank,
I've been a long time Sandisk user(sounds like a bad habit, lol) thankfully I've not had any problems, I have though
been reading lots of positive things re the Samsung cards, maybe there is a viable alternative at last!

No doubt that Samsung know how to make memory chips, and Samsung flash memory has a very good reputation, for example their SSD-drives. They don't seem to make CF-cards, though - I use only Lexar, Toshiba and Sandisk in my cameras. Actually I have Samsung SD-card in my car's dashboard camera :)
-
Never saw any reason to stop using my Sandisk cards (CF, SD) as there has been no problems with either format. SD cards are too small, but that is hardly the fault of Sandisk ...
Nice to know there are alternatives in case I need to replace lost SD-cards in the future. Not an unlikely event, I dare say.
I have gone all in for Samsung SSDs after having had my share of troubles with the products of other makers. The Samsungs (120 to 512 GB sizes, about 10 different units) have been behaving well now for over 3 years.
-
Samsung had some problems with the 840 EVO SSD, but apart from that glitch their SSD's are excellent. I have a Samsung in my Lenovo laptop, the others are Intel 520-series - also very reliable workhorses.
Recently I have used some Toshiba Exceria Pro CF-cards, they are considered to be extremely reliable, and so far they seem to work perfectly in my cameras.
None of my Sandisk cards have failed me, but one or two Lexars have behaved strangely, so they are dumped in the bin.
All my cameras have two card slots, that is a feature I really appreciate, it gives me a bit more ease of mind.
-
I have 2 Samsung and one Intel SSD, about 15 CF and SD from Sandisk which all work pretty well and now I use the 32GB superfast Samsung Pro in my D600 plus the 64GB in my X100T.
Most of my Sandisks are 45MB speedgrade, some 60MB, some older 30MB only.
With both the D600 and the X100T the difference is clearly noticable.
It is a pity Samsung does not offer CF. I would replace my Sandisks in the D3 right away.

I recently had to recover data from two Sandisk cards, one CF and one SD. The fault was entirely mine, as the data was already on my computer (don't ask).
I still had the cards, but they had been formatted in camera several times since I had transferred the lost data. I downloaded RescuePro from Sandisk, and over the course of a few hours it recovered all the lost images, which I then transferred back to my computer (and immediately backed up!). A few days later I had an email from Sandisk asking me if RP had worked. I replied positively and received a personal response.
So I am feeling warm about the company at the moment.

Me too have had a corrupt Sandisk card - since then used Lexar as it is "paired" with Nikon in SA (same distributors)
Good to know about an alternative though - thanks for sharing.

Anthony, did you find a free, working version?
Some days ago i tried to download Sandisk Rescue Pro, but all I found was a demo version that only showed a preview of the files that could be recovered - if you purchased the program!
(Lexar have always offered free, fully functional rescue software.)
-
Bjørn, sadly, I had to pay for the program. I did hunt around for free recovery programs. I found a few, but they were all so restrictive that I had to pay up in the end. I had paid money for the event which produced the lost photos, so I decided that the RescuePro fee was a minor extra cost of the event. And it did do an excellent job.
-
I found a Linux Program that boots up a whole linux system from the CD, then opens the SD write only for rescue and writes the contents to a disk of your choice. Was quite able. I will write here as soon as I have the name of the program.

This IS a solution. But as far as I remember the software I was using on UBUNTU live system even hat a GUI...
-
I had a problem, long ago, with Lexar. When I called Lexar they basically laughed at me. I've been using SanDisk ever since and none have failed me. Presently, I'm using SanDisk UHS II (280 MB/s) in my Fuji's. But I do own three Samsung's, a frig, a dishwasher and most recently a Tv.

Yesterday my Intel SSD died on me.
I get a third Samsung 850pro as replacement

After another 2.5 years I have more good news and bad:
1) I had more SanDisk cards fail on me, I still have to find one SanDisk 64GB card that does not die on me. The older Cards Ultra / Extreme up to 32GB CF & DS are still doing very fine. I will never buy SanDisk again
2) All of my Samsung cards, and I have plenty, are still very very reliable and fast.
3) All of the shops in my hometown unlisted Samsung cards due to their very unfriendly brick & mortar retail policy: they do not accept any returns, even of cards that came dead on arrival. Source: Shop managers. I buy the cards at amazon now.
I just bought another one, a SUPERBARGAIN! 128GB and very very fast: https://www.amazon.de/Samsung-Speicherkarte-Adapter-Frustfreie-Verpackung/dp/B06XFX9N84
The old "Pro+" is as fast as the new "Evo Plus U3". Both are labelled to read 90 MB/s, which is 90*10^6 Byte/s or 86 *2^20 Byte/s, depending on your labelling preference (ISO or "traditional").
Measured performance is: 83,7*2^20 B/s read and 64*2^20 B/s write
NOTE: This is average over the whole card, masured with the tool H2testw programmed by my former colleagues at c't magazine.
Reliable Source IMO: https://www.amazon.de/gp/customer-reviews/R13FXNURMKCX2Q/ref=cm_cr_dp_d_rvw_ttl?ie=UTF8&ASIN=B06XFX9N84
FAR ABOVE THE PAY GRADE! Comare this to real world SanDisk cards: slower or much more expensive.
NOTE: There are older Series called "EVO" and "Evo+" ... these are the ones you do not want to buy! You want the "Evo Plus" (written "Plus" not Symbol "+"). The older cards are much slower and only write 20 or 30 MB/s respectively. The modern cards have the number "3" written inside the U-Symbol.
real world write performance is higher with big files than average synthetic:
or lower with small files:

Frank, thank you for the further info. The news doesn't sound nice to me...
Now that I'm using Panasonic GH5, I want to replace my UHS-I SD cards to UHS-II ones (V.90, if possible). Samsung UHS-II cards don't seem to be available even in Amazon. The reasonably priced cards are either Sandisk or Toshiba, and maybe Sony, but, if I understand correctly, the flash memory for Sandisk is made by Toshiba. My slower (UHS-I) Toshiba Exceria cards are working just fine, but I don't use them as extensively or heavily as yours.
Panasonic UHS-II cards are still quite expensive. Lexar disengaged its flash memory division. I haven't trusted or even looked at ADATA due to its early defective products. Oh, well.
-
Another Note: speed grade is dependent on capacity. The 32GB "Evo Plus" is only rated U with a "1" inside, seems to deliver 20 MB/s in real life (ISO), not 64 MB/s (binary)

Before dumping a misbehaving SD cards try using the SD Association's SD card format utility. After that install the card in the camera it will be used in and format it again. The camera will do a quick format and prepare the card for it's use. The SD Association's utility has a number of options so select what you need to correct problems or for security if needed.
This utility can't repair defects. I don't know if it can mask errors in a card that is near its end of life. If in doubt it's not worth using a questionable card. If a card was ejected improperly or the camera shut off too fast this utility may help.

The trouble with Sandisk cards was always that they suddenly turn read only, although there is no read only function on micro SD cards! No formatting possible on any operating system. Can be read only in the Android device I have used the cards in.

This sounds like a failure of the slide lock. I wonder if it can be defeated? If closing contacts allows the card to be written to then maybe cleaning would fix such a card. I can't find an SD card I can butcher.

There is no lock on micro SD cards. Many cards come in this format today with a slide in adapter

Sandisk has a limited lifetime replacement policy and have replaced failed cards for me long out of warranty. A working sandisk is better than a broken sandisk even if you don't plan buying more. Perhaps it is worth looking into?

I've only bought one of those and installed it in my phone. :)

You suggest I send them my card with all my data on them? Data I cannot delete or alter?
Look: These are only my Sandisk cards currently left after selling a lot of old cameras with wiped cards in them (D70, D70s, D7000, D3, D600) and of course not those that went back to the place of purchase for defect / refund

Just bringing it to your attention that they may replace your failed cards.

You are right. I had RMA and free UPS sticker within hours. I send the card back for replacement.
Thank you

I bought another one of these cards ( Samsung EVO Plus 128GB, Class 10 (100MB/s) - microSDXC Karte, price: 40,75 EUR incl. s&h at ebay.de) and did test it to verify the capacity and performance with the tool of Heise-Developer Harald Bögeholz, Mathematician, Genius, former Colleague of mine at ct.de.
Result:
122.090 MByte tested (capacity 128.000.000.000 Byte ISO)
writerate: 75,7 MByte/s (average over the whole capacity)
readrate: 81,4 MByte/s (average over the whole capacity)
software version: H2testw v1.4
