Your old cards will work perfectly! Unfortunately, back in, maybe 2011-2012, Sandisk started using a badly designed/badly tested controller, most likely in an attempt to obtain a faster throughput. If the card is stressed it will fail. 'Stressed' could be due to heat. All my Sandisk cards failed after extended recording times. Some cards just flipped permanently to read-only, others became non-readable. A Sandisk tech once told me the read-only flip was 'by design' to prevent a total loss of data. I have also had a Sandisk fail simply by reading it in my card reader! I can't remember exactly how many failed Sandisks I have had, but I think it's in the order of 5 or 6. I have never had any other card fail even though most of my cards are other brands. All my cards are genuine.
Before about 2011/2102 Sandisk were my favorite brand, but now I wouldn't even use one if I was given one for free, except for testing of course. The risk of losing all my data is just too high. I do, however, have a 128GB Sandisk, but I dread using it....
I know Sandisk (still) have a good name, but I don't know why - maybe because they are fast and failure rates aren't important? Or maybe they work OK when when they don't have to run in a confined area where heat could be a problem?
I don't favor any cards - I just disfavor Sandisk! Having said that, most of my cards are 32GB Kingston from different batches. I have also tested other 32GB brands such as Samsung, PQI and PNY.
I tested the cards using firmware that I knew used different chip manufactures codes and found Kingston cards to be the most reliable. No cards, except Sandisk, failed physically.
If reliability is important then I recommend class 4, but even class 4 can have their quirks and the newer Sandisk class 4 are just as bad as class 10. The original (first) Sandisk class 4 were great, but then they changed their controller...
Having just read this & in light of my recent post about "just today I bought a SanDisk"............(which I can return)
should I do that & go with a different brand ? If the SanDisk don't work for Isoprop, they sure as heck are not gonna work
for me BUT, I would still like to have a 64 as opposed to a 32 GB.
Feedback appreciated.
