💾 Amazon Basics 512GB microSDXC Memory Card with Full Size Adapter - A2, U3, 100 MB/s Read Speed Review

I received this microSD card from Revain Basics a few weeks ago and it works exactly as promised. Its performance is very similar to my V30 U3 Samsung and SanDisk microSD cards BUT only this Revain Basics microSD card has a 1-year warranty, while Samsung microSD cards have a 10-year warranty and some SanDisk microSD cards have a lifetime warranty. Since these cards are basically identical in price and performance to branded cards, why not buy branded cards that have both a longer track record…

There's not much to consider with a MicroSD card other than read/write speeds. They were excellent (95 down and 70 up) and as expected on a USB 3.1 SD reader. Build quality and packaging are quite good. The package includes a full size adapter along with a reusable hard plastic case that fits both.

Crystal Disk Mark gave me excellent speeds: read 90 and write 70. In this case I would like to put it in any camera or smartphone. I like the case in which it was delivered. Most other brands don't care about storage for these cards anymore. Good to see her again. It sat securely in place without swaying as expected. Overall a great card. Highly recommended.

They are really very good, CrystalDiskMark gives ratings that are on par with known brands, but I found that the reference program is sometimes very misleading because you are copying a large folder with many small files on a micro sd will very often slow down to an excruciating snail's pace, this RevainBasics was no different in that regard, it's elm but actually even as slow as it actually was 2-3x FASTER than other big brands So all in all that's it the best 64gb micro sd cards i have.

As far as read and write speeds go, it's about on par with SanDisk, maybe a little slower than Samsung, but only minimally - nothing you realize you are actually used. Longevity is really the only other differentiating factor here, but until something goes wrong all you have is a reputation for moving on. There is a serious risk of premature failure with cheap non-branded ones and the difference in price is usually not enough to justify the risk. As such, I always recommend sticking with…
