Anyone have experience with Kingston industrial microSD cards? I’m seeing 16GB around $20.
Looking for a couple backups (for something like a ColdCard) and $40 for the ones sold by CoinKite just seems like a lot.
I do recognize these cards aren’t cheap and it can be tough to find good ones, so if the advice is “just go with CoinKite”, I will. Also trying to gauge what sort of storage space I’d need for a rarely-used cold storage signer.
Thoughts? #asknostr
I did enough research to come to this conclusion. It’s a little rabbit hole but less is more in regards to security when splitting hairs on storage size
Just go with coinkite because they doing QA
SD card are super unregulated and mess to get tested chips
This is why I’ve been hesitant/hoping to find a reputable company with reasonable pricing
The 8gb San Disk are the way to go. There's no reason to buy a 16gb for a Coldcard. 8gb is plenty of space for what you need. Amazon has a good sale on multi-packs of these SanDisk cards.
Perfect 🤙
I use these too. I like the Q BBQ codes though. SD cards suck.
I’m working with an MK4 (and of course have steel too) so just looking for redundancy (and also forgot that the coldcard doesn’t automatically come with an SD card when I bought a second one)
Thanks brother! Appreciate you
Samsung, Levar/Micron, or SanDisk all make their own wafers. Kingston creates a spec and buys what’s available. If had to choose, I go with one of the first three. But the difference is going to be small.
The bigger thing to think about is that you don’t want to use sd cards as long term storage. They degrade over time. They’re the cheapest part of the wafer before it becomes scraps. Definitely something you want to check periodically.
Thanks homie, that’s exactly the sort of detail I was wondering re Kingston.
And 100% - these are backup backups — nothing replaces cold hard steel 🫡
