The SanDisk Extreme Pro dominated the IOzone tests on the Raspberry Pi 3 B+, placing first in every category but 1,024K random writes and 4K sequential writes. The same cards that did poorly on
All right. I have both a 64GB SanDisk Extreme Pro (95MB/s reading, on a Nikon P1000, as the P1000 sometimes has problems turning on with a 45MB/s SanDisk Ultra) and a 128GB Kingston CANVAS Go! Plus (170MB/s reading, 90MB/s writing, on a Nikon A1000), and will see how they compare in practice (the A1000 is a daily companion and the P1000 is for View community ranking In the Top 1% of largest communities on Reddit. SanDisk Extreme Plus VS Switch version . So in short, I did see that the SanDisk Extreme Plus has a maximum read speed of 170 MB/s VS the 100 maximum of the Switch version (the red and yellow cards,with the mushroom and star). even the Ultra has a higher maximum reading SanDisk Extreme には V30 ラベルが付いています。これは、30MB/s でビデオを録画できることを意味します。 この速度は、4K、 ハイエンドミラーレスカメラの使用 そしてデジタル一眼レフカメラ。 一方、SanDisk Ultra には V ラベルが付いていません。A SanDisk Ultra card has a max write speed of 80MB/s, while the SanDisk Extreme cards reach up to 90MB/s. This refers to how fast a photo or video is saved to your memory card. So, the SanDisk Extreme will have shorter buffering times. The read speed of the SanDisk Extreme is up to 160MB/s.Even worse, I started RMAing the cards, and the brand new micro SD cards, straight from Samsung, started failing within weeks, too. And this wasn't a security camera\dash cam situation, or extreme temperature\weather conditions. I swapped all the Samsung cards for SanDisk Ultra cards, and haven't had much of a problem since. 18 sec - SanDisk High Endurance 64GB 15 sec - SanDisk Extreme 32GB 15 sec - SanDisk High Endurance 32GB hdparm (2nd run): WD Purple 32GB: /dev/mmcblk0: Timing cached reads: 1670 MB in 2.00 seconds = 834.73 MB/sec Timing buffered disk reads: 132 MB in 3.04 seconds = 43.36 MB/sec. SanDisk High Endurance 64GB: It's appreciably faster than my Sandisk A1 128GB card, but no idea how it stacks up against Samsung's version. The SD Extreme has a 60% faster read speed. That said the difference in load times isn't going to be noticable to most folks. If money is no object, go SanDisk. Both Evo Selects and SD Extremes are UHS U3, A2 V30 mSDXC's. .
