You need a latest gen reader to get full speeds
So most of the reviews here were done with previous gen SD card readers. These new gen EVO Select cards comply to new standards and those new standards require new card readers in order to get the full speed the card is capable of. You'll need a latest gen card reader to get the upgraded speed for your computer.

Samsung has a new card reader, but it seems that you cannot buy it separately, at least I cannot find it for sale separately after searching everywhere, including Samsung's website. [[ASIN:B09B1FN5S3 There are card+reader bundles available for their new PRO Plus cards]], but there is no bundle available with the EVO Select cards.
I found a few new UHS-II readers from Kingston. [[ASIN:B085P4Y1F1 This one is for full size SD cards]] but it works perfectly using the Micro to SD card adapter that ships with the EVO Select cards. The Kingston is only $10 (at the time of this review) and it works perfectly. The results in the attached screenshot were done with a new 512GB EVO Select and this card reader.
Kingston also has [[ASIN:B085P5FDXQ a micro SD card version of the UHS-II reader]] if you prefer not to use adapters, but it's slightly more expensive at $12.30 (at the time of this review). But I suggest that you get the regular SD version since it's not only less expensive, but far more flexible since you can use both full size SD and micro SD with an adapter, whereas you cannot use the micro version of the reader with full size SD cards if the need ever arises.
As far as the Samsung EVO Select card itself, it's a quality Samsung card, which is all I've used for the past decade. You should note that no matter what the speed of the card that you buy is capable of, if the device you're going to use it in is not capable of that speed internally, you'll only get the max speed of that device, but not necessarily the max speed of the card. As this is a brand new generation SD card, most devices are just not capable of the speed this card has internally at this time and you'll likely not see any benefit from it in anything but the very latest high end flagship phones and very latest high end DSLR cameras, if that. At this time, most of them simply won't have internal interfaces capable of these read/write speeds yet. Future devices probably will.
So you may not need or see any benefit other than faster computer transfers using this very latest card for your device (and only with the very latest gen SD card readers). With that in mind, you may save money buying a slightly older gen card. Just bear that in mind before you spend your money.
