This is my first China-made 64GB MicroSD card review. I bought 3 pieces of them (2 from SomnAmbulist and 1 from Hsthe sea) in late 2023. However I noticed that the test conducted is greatly affected by the equipment that you use for such task. So I just want to provide what I did and what equipment I used and just give a overview of the test results.
I selected this MicroSD card is due to the A2/U3 speeds. I was hoping it would be faster for its price.
Equipment used:
- Samsung Galaxy S8 with SD card test app(Android)
- Laptop using a USB 3 card reader
Since I use different laptops, I cannot be sure all the test results are consistent since I switch 3 of them to ensure their batteries don't die if not used for too long since they are all quite old laptops.
So below are the 3 MicroSD cards test results:

Actual test from Samaung S8:
Read: Up to 77Mb/s
Write: Up to 25Mb/s
From the Samsung Test results, its Read/Write speed was normal and write speed is slower at 25MB/s. This brand seems like its Read/Write speed is slightly slower than some other China made MicroSD card.
I also selected this MicroSD card for its rated A2/U3 speed as I was having too many hopes as this brand seems to be pretty hot in the online shopping platform.
Write: Up to 25Mb/s

SomnAmbuslist 64GB MicroSD Card($5.40/$3.32 actual purchase price)
Actual test from Samaung S8:
Read: Up to 77Mb/s
Write: Up to 21Mb/s
This card's write speed is slower than the earlier card. So I don't recommend this card but I noticed that quite a few people actually bought this card as there are a few more reviews after mine.

I actually found a Youtube video reviewing this MicroSD card and has given good reviews for this card. I managed to find it online and purchased it.
Hsthe sea 64GB MicroSD Card($5.31/$3.21 actual purchase price)
Actual test from Samaung S8:
Read: Up to 69Mb/s
Write: Up to 37Mb/s
Read: Up to 69Mb/s
Write: Up to 37Mb/s
The Samsung speed test shows that this card has the fastest write speed(37MB/s) but slightly slower read speed compared to other cards. In Aug 2024, the price shot up to $5+ (Similar price increase for above cards as well) so it is not worth purchasing now. That is why I started another MicroSD card review.
