MOST RELIABLE SD CARD !!!!

Mon May 10, 2021 11:04 pm

Hey Everyone?

I am using rasp pi for my IoT fleet,
I get a lot "kernel panic" error.
I would be happy to know what is the cause for that ??

Moreover, I would love to hear whIch SD cards are absolutely top-of-the-line most reliable, and robust.

Thx in advance

The current top recommended micro SD cards for use with a raspberry Pi are SanDisk A1 rated cards, followed closely by any other brand with specs in the same class.

It is not just the card, it is the OS.
Not sure what OS you are using?
I choose PiCore and Ultibo for my IoT devices.
That way I can control the erase/write cycling on those.

Old SLC, single Layer Cells have more erase/write cycles.
My longest lasting cards are old SLC 128MB SD cards.
You need to minimize erase/write cycling.

The 16GB A1 Sandisk are my preferred consumer cards for Linux use.

It would be nice if someone made FRAM or similar uSDs, 128MB is all I need.
Guessing IoT guys would use industrial cards?

Search the web for "industrial grade microsd card".

In general, even the best sdcards will wear out and fail eventually when you're writing to them a lot. Run these systems with read-only filesystems if you want them to be reliable.

Sandisk have come out tops in our testing. We've not had a single failure due to random power drops on Sandisk.

+1

I have Sandisk A1 class cards in all my Pi's for years and simply never see failures or corruption.
They are fast enough that I don't feel an urgent need to use an SSD (and 8GB Pi4's have plenty of space for a huge disk cache).
