Posting this deal to mainly highlight the need for an appropriate
usb reader that supports UHS-I DDR208 protocol allowing over 100MB/s read and write speeds for these 2021 EVO select and PRO Sd cards on sale this week. Previously only Sandisk Extreme pro used this protocol to achieve up to 170MB/s read speeds and also needed a new sandisk reader. Most devices and built in card readers in laptops and usb/thunderbolt dock only support UHS-I DDR104 and only up to 100 MB/s read speeds.

I mostly use the SD card in security cam now.

BTW, I'm pretty sure the EVO Select cards are rebadged versions of existing Samsung cards, an Amazon exclusive label, that has allowed Amazon to sell the same for cheaper without canabalizing Samsung's sales elsewhere. That's the impressive I've had and it's why the Select cards have been an excellent value.

I don't need another card, but I do like high transfer speeds.
I write media files to uSD to play on my tablet or phone and appreciate fast writes.
Transferring to device direct by USB or wifi is so much slower.
Kind of defeats the idea of leaving the card in my ultrabook, or at least defeats the idea of paying more for a fast card, maybe.
I wonder about my old camera too. Recently bought a similarly rated SD card, hoping it would speed up my camera reaction time, but don't notice a difference.

Thank you. Yes it was to have a thread to point out unless people get a new USB reader supporting the uhs-I ddr208 protocol most people won't see a difference for sustained transfer or write speeds in most devices when comparing the older Samsung green line vs newer blue line of Evo select (same with pro lines) and should just buy the cheaper one.
There are some reviews looking at the random write speeds showing faster speeds at queue depth 1 using the new card reader and SD cards but I couldn't find any reviews that indicated whether that improvement still existed with current uhs-I 104 card readers or devices/phones.
