Pi 5 second SD card bricked

high endurance SD cards

That “endurance” (or durable) type cards are the wrong ones for this use case.

Would a cheap $15 ssd like this be good for a rpi?

Completely different use case and you misinterpreted your mileage to be valid for a complete different task (which is it not!) If you use such cards for continuous recording like the seller expects (“Full HD (1920x1080) video content recorded at 26 Mbps”) the write amplification factor will be probably always be 1. So for every (m)byte requested from the OS to be written to storage also exactly one (m)byte is actually written to flash. That’s great b…

Do you mistake them for (expensive) “industrial” ones by chance?

But these “write intensive” tasks are “big junks” or sequential writes (like a video or images). This types of writing will probably have a WAF (write amplification factor) close to 1 because they certainly always will write full “pages” (the host writes will very much equal the flash writes). So this is the perfect scenario for a flash storage as there is virtually no write amplification and you will get the maximum lifetime for your flash storage. If you look at the details for this card: Mi…

The best, when using SD cards, is (like the ha docs tell us) to use A1/A2 type cards.

Micro SD Card.

• Ideally get one that is Application Class 2. Check for the label A2 on the card. Application Class 2 cards perform better especially on small read and write operations and are better suited to host applications.
• Make sure to use a card that provides at least 32 GB.

The industrial type doesn’t make sense IMHO as for that price you get a proper ssd from one of the few flash manufactures left

Next best thing with SD cards is oversizing to have as many “fresh” cells available as possible which really leads to longer endurance (with the same amounts of writes)
