China Made MicroSD Card Speed Test Review Part II

Recently bought 4 cheap China made MicroSD cards to test whether if they are worthy purchase since I was looking some 64GB replacement as I cracked 2 pieces of 64GB MicroSD cards due to poor keeping condition. Since I did the speed test with my laptop and it was all so slow (within 18+MB/s for both read and write speeds), I will not use these results and will be using the results from my Samsung Galaxy S8. 

This is the first MicroSD card that I found and purchased with worthy Read/Write speed advertised.  However, the read speed is overstated. As for write speed it is worthy since it is higher than those earlier purchased China made MicroSD cards in the earlier review.

Advertised Read: Up to 100Mb/s
Advertised Write: Up to 45Mb/s

Actual test from Samaung S8:

Write: Up to 48Mb/s

==========================================================================

This is the first 128GB MicroSD card that I purchased to test out since it promised pretty high read/write speed at a cheap price. Even though the 100MB/s read speed is overstated, the 57MB/s write speed is the fastest from these cards that I purchased. So likely I would be purchasing this for my mobile phone and also my old tablets if they can support.

==========================================================================

I purchased this small(32GB) MicroSD card to test out whether its speed is as advertised and will buy more if it is. However, it is the slowest (read/write) compared to all the MicroSD cards that I purchased will not purchase it again.

The performance from this card is the worst that I have purchased. It really sucks. Will try to get a refund if possible.
