    Google Play’s Best of 2021

    I tested two 1TB microSDXC cards in four Android phones from 2016 through 2020. What kind of differences can you expect between U3/A2 speed cards from different price classes?

    Images and graphics related to this post on Imgur: https://imgur.com/a/3nCa34x . There is also a Google Drive spreadsheet with my measurements and details of the hardware used.

    TLDR;

    A smartphone's internal storage will typically offer you up to 10x higher read and write speeds than removable microSD can. The Sandisk Extreme PRO 1TB (U3/A2) offers double the write speed as the more budget-oriented Amazon Basics 1TB (U3). Read access is very similar all around. If you do write-intensive things with your storage, such as 4K video, it could be worth looking out for deals for a premium brand SD card, rather than going for the cheapest U3/A2 option.

    In spite of using the Sandisk Extreme Pro 1TB in 3 different daily drivers over the past year, I saw no degradation of its performance. By contrast, I did see such degradation in some of my older cards in my 2020 test. However, note that I never exceeded 85% storage on the Extreme Pro 1TB.

    Becoming a rare feature

    Micro SD seems to be disappearing from new smartphones. Of course iPhones and Google Pixels never had SD slots for storage expansion. But in recent years, also Samsung (which produces microSD cards) has released flagships without the expansion option. Of course plenty of midrange and budget Android phones still give you the option for removable storage. The only major brand that currently offers the option with their flagships, is Sony with their Experia 1 and 5 lines and the recently announced Pro-I.

    Until early this year, when they announced leaving the smartphone market, LG also produced flagships with SD slots. For this comparison, I used 4 of my LG phones released between 2016 and 2020.

    2020 vs 2021: two new phones and two the same

    Last year, I did an elaborate test of seven A1/A2/U3 microSDXC cards in four Android phones that I had available then, including one V20 running Nougat. In 2020, I did not have the V60 and V50 yet to test with. Last year, two of the phones ran Android 10, this year three of the four run Android 11.

    During my most recent tests, I did not find anything that contradicts with my findings from then, so I still highly recommend the post, if you haven't read it already.

    01 - Read Speeds (MB/s)

    Brand Internal Storage 1) Sandisk Amazon Basics
    Speed branding A2/U3 (Extreme PRO, Black/Gold) U3
    Capacity 1TB 1TB
    LG V60 1394 90 80
    LG G8X 745 66 77
    LG V50 732 69 84
    LG V20 456 73 58
    Average 78 76

    (Sequential) Read speeds - My takeaway: Relatively small range between cards: 62-78 MB/s

    02 - Write Speeds (MB/s)

    Brand Internal Storage 1) Sandisk Amazon Basics
    Speed branding A2/U3 (Extreme PRO, Black/Gold) U3
    Capacity 1TB 1TB
    LG V60 726 63 27
    LG G8X 488 62 26
    LG V50 479 60 28
    LG V20 154 45 22
    Average 59 26

    (Sequential) Write speeds - My takeaway - Large range: 26-59 MB/s - so expect big differences in performance. The speed differences are also significant on the oldest V20.

    How I tested

    • Room temperature - in the frisky 17-19 Celsius (62-66 F) range in my case
    • No case or skin - cases and skins can impact heat dissipation and thus SoC temperature and influence results
    • Airplane mode ON - poor cellular (indoors) and Wifi reception can keep the SoC and battery busy, which can blur the results
    • Localization (GPS) OFF - same reason as airplane mode
    • Anti-malware de-installed - BitDefender Security installed on several phones. I had it de-installed for running the tests.
    • Battery in the 30%-100% range - Below 30% battery, heat and performance effects can occur. Not something you want to blur results with.
    • No charging during benchmark runs - Charging = heat = potential performance impact
    • No USB-C devices connected during benchmark runs (although I use it for screenshots in between tests)
    • At least 34% free space on tested medium. Last year, I noticed that available space can have an impact on the performance, especially with certain longer used cards. For this 1:1 comparison I actually cloned the contents of my Sandisk daily driver card to the Amazon Basics one. So both had the exact same data set.
    • Like for the 2020 tests, I started out with using the elaborate AndroBench app. I ran 3 tests for each combination. Unfortunately, the app is no longer maintained and it does not work well with SD cards anymore since Google made changes in Android 11. It does still work well with internal storage and on the V20 running Oreo. Several other apps had similar problems, but SD Card Test by developer Zoltan Pallagi worked OK.
    • 1) = Internal Storage tests in the table were done with taking the average of 3 AndroBench runs. MicroSD tests done (only one run per device, due to time constraints) with the free version of SD Card Test by developer Zoltan Pallagi

    Overview of my raw test data and analysis

    About the (Androbench) screenshots: You can make sure-fire screenshots from the AndroBench log using an external keyboard (USB using hub or OTG cable or bluetooth), provided the external keyboard has a PrtScr key.

    Note that AndroBench tends to reset very easily to the internal memory setting, e.g. if you connect or disconnect USB-C devices. So always check which you are measuring: internal or microSD.
