Hmm, your statement: “Very impressive is the fact that performance jumps at the 64MB file size mark”

Don’t you mean 64KB?

I’m sorry to be responding to my own post, while Googling, I found this bit of info about wear leveling from Sandisk, but this is for their Mini SD, not Micro SD card line. I couldn’t find if the same applies to their MicroSD line.

ERROR CORRECTION FOR ENHANCED RELIABILITY
The card’s built-in Advanced Wear Leveling and Error Correction Code engine enhances endurance and reliability. https://www.sandisk.com/home/memory-cards/sd-cards/extremepro-sd-uhs-i

I would expect Samsung, being one of the biggest flash/transistor based storage mediums would have something similar in their high end SD cards. Hence, that would explain the price difference.

Again, if you could help shed some light on “wear leveling” issue and or maybe create dedicated section on your site it would be very much appreciated.

With technology advancements user focus is shifting towards powerful and expensive cellphones and tablets that utilize MicroSD cards. Many folks pay for that extra fast Samsung S7 and would only want the “best” micro SD in it.

Hi Les, Do you happen to know if any of the Micro SD cards implement wear leveling? I feel this is more important than just a synthetic bench mark on a fresh sd card. If there’s no wear leveling implemented, rather than buying a small capacity but fast (U3) SD card, it would make more sense to buy larger capacity but relatively slower (U1) card and delete pictures from the card less frequently (thus reduce rewrite on the used transistor). Do you see where I’m going with this? If there’s no wear leveling on Micro SD it would seem Raspberry users are screwed no matter what size they choose cause certain temp files of the OS would eventually “burn a hole” on their SD card.

Wear leveling support for us Raspberry Pi data tinkerers might useful to include or maybe even worth an additional article.
