This is why most smartphones still include an expandable Micro SDCard slot so you can increase on your phone storage. The maximum amount of expandable storage varies from device to device, so you should consult your phone specs first before buying external storage. But most phones now support upto 128GB with a few premium flagships accepting upto 1TB of external storage. This particular Samsung Evo is classified as Secure Digital High Capacity (SDHC) type of Micro SDCard. These Micro SDCards supports between 2 GB and up to 32 GB of storage. It belongs to Class 10 speed class UHS-I, U1 meaning it supports minimum write speeds of 10MB/s. The product cover says the Micro SDCard supports read speeds of 95MB/s and Write speeds of upto 20MB/s. I wanted to put this to the test given a number of fakes in the market.

With both software, I was able to hit about 28MB/s write speeds and 30MB/s read speeds from my laptop. The write speeds performed as rated, but the read speeds are half what’s rated. I expected something close to 95MB/s. It turns out, it’s because I was using the Micro SDCard Adapter on PC. To get close to rated speeds, I have to use a UHS interface which I can only get from a smartphone. So I downloaded SD Card Test Android App and inserted the Micro SDCard directly to my Android phone. I was not disappointed at all by the speed tests. I was able to hit 26MB/s write speeds and 87MB/s read speeds which is much closer to the rated 95MB/s speeds. The Samsung Evo Plus has 4-protection modes including water proof, magnet proof, temperature proof, and x-ray proof. There are 64, 128 and 256GB variants to carter for your storage needs.
