A perfect microSD card for low memory cell phones
The penalty for a low end phone, like the Galaxy A20, is not just missing a wireless charging option, but also not having adequate storage space. Especially with all the apps, and pictures/videos.I needed a microsd card which won’t break the bank and that has adequate speeds. I did my research for the minimum speeds and already decided that 16GB, will be enough for the Pictures and files the Phone allows to be saved on SD.The package included a life saver, USB and USB C adapter which allows me to read all my micro SD cards. See picture. The included SD adapter is nice. Although I do not anticipate using it more than once in a year. The dual adapter is much more useful.As for the speed, I tested it with actual data (my many pictures and few videos), going back and forth between phone to SD. No issue observed, and the speed matched the advertised numbers. On the many small files it was about 20% lower, which is as expected. With the big video files, it was about 5% faster than advertised, again ’as expected’.No issues observed, and the card was fully functional the moment is was inserted in the phone, i.e. immediately recognized.Note that a review mentioned that the USB/C reader corrupted his data. I’m not sure how is it possible, unless one writes vs reads. In my case, I had no problem reading 128GB, 64GB, and the 16GB on my computer.A great little package.

Unirex 32GB U1 MicroSD Card with SD Adapter: $8.99 at the time of review.
I’ve been a Raspberry Pi enthusiast for a few years now. The thing I love about the Pi is its flexibility and that includes the microSD card slot for a system drive. I decided on this microSD card from Unirex for my latest project (a Raspberry Pi-based implementation of Home Assistant). Read on to see why that might not have been the best choice.
This microSD card & adapter package is a full color cardboard clamshell. It’s a full retail package that you might expect to find at your local Best Buy. It includes the card, an dual port USB-A & C adapter as well as a full sized SD card adapter. It’s a good looking package with a nice variety of options for accessing the card.
Unfortunately, the performance of this microSD card falls well short of the fit & finish of the package. The rated performance from Unirex is 50mb/s. While I was able to achieve a read speed north of 70mb/s (a pleasant surprise), I was never able to get a sustained write speed of over 10mb/s. And that’s really the crux of the issue. Besides reliability, speed is really the only other metric by which to judge storage media. And I’m afraid, frankly, that this microSD card fails the performance test miserably.
------------
*The Good*: Nice assortment of access options. Faster than advertised read speeds.
*The Bad*: The USB-A/C adapter is USB 2.0, limiting performance.
*The Ugly*: I never got a higher write speed than 10mb/s, a mere 20% of the advertised speed.
*The Bottom Line:* At the advertised price of $9, this card is probably fine for some uses. But the inability to reach even half the advertised speed severely limits its practicality. Two stars out of five for basic functionality, but poor performance really holds this card back. I would not order this again.
