5.0 out of 5 starsWOW-DAMN GOOD MicroSDXC - Results are very good
Reviewed in Canada on February 13, 2024
I have been investigating quality MicroSD cards for sometime now, for drones and Raspberry Pi computers. Read/Write Speeds are critical to proper performance, as well as reliability.
After much research and recommendations I focused on the SanDisk products, but soon found myself in a sea of counterfeit memory cards. With more research I found that SAMSUNG has a verification app you can run to verify if your SAMSUNG card is legitimate - very helpful. I therefore switched to SAMSUNG, they have been very good and very reliable and well priced. I do know that Amazon has an agreement with SAMSUNG and sell the SAMSUNG EVO Select cards exclusively to Amazon for distribution. However, while searching for a new batch of MicroSD cards I came across the Amazon Basics branded MicroSD cards, the reviews were good and therefore decided to buy a couple of their 2-pack 64GB boxes on a special deal for a recent Raspberry Pi project.
Using the Raspberry Pi Diagnostics app to verify if the SD card will pass or fail (see attached images) I was surprised to see how good the Amazon Basics MicroSD cards ranked.
SUMMARY: Test performed on Raspberry Pi 4B with 64bit PiOS installed - using Raspberry Pi Diagnostics App.
