Review on 📷 JUANWE 2 Pack 32GB Memory Card - High-Speed TF Card for Smartphone/Bluetooth Speaker/Tablet/PC/Camera (2 Pack) by Jeff Ross

I've bought all four brands of 32GB micro SD cards that were on sale on Prime Day for $4 or less. claimed actual x-factor read write speed/read speedamplim 667x 100 MB/s ?MB/s 27.7 MB/s 35.3 MB/s speed constant all the way netac 600x 90 MB/s >10 MB/s 18.9 MB /s 35.0 MB/s Speed is consistent across Juanwe ?x 70 MB/s 10-20 MB/s 15.8 MB/s 20.0 MB/s Read started at 29.2 MB/s but fell fast to 20.0 MB/spowee 667x 100 MB/s 20 MB/s 19.7 MB/s 34.4 MB/s Speed consistently stable Lexar 633x 95 MB/s 70 MB/s 11.8 MB/s from 34 .0 MB/s Read started at 17.9 MB/s but dropped to 12.7 MB/s in 15 minutes. The Juanwe card was the slowest of the two unnamed cards. However, remember that any write speed over 10MB/s is within the normal range. I also compared the well-known Lexar brand, thinking that it would outperform the cheap Chinese brands, but in fact it turned out to be the worst! (Bought here at Revain last month too) Tested with a verified copy of H2testw running on an HP 15-db0048ca laptop with SD slot built in.
