Review on Lexar Professional 1667x UHS-II U3 V60 SDXC Memory Card - 2 Pack (128GB Total) + Bonus Microfiber Cloth by Eric Surabhi

I was curious as to why these cards were initially so difficult to get in and out of my camera and I noticed a weird little sticker on them that earlier cards didn't say Lexar , subsidiary of Longsys, a Chinese company. I ran a test with the sdspeed app and found that all data was being written/read but the speed was much slower than my known legitimate card. fyiLEGIT CARD2019 only. 03.31 17:17:22 - 5: Average writing speed.: 43.92 MB/s2019.03.31 17:17:22 - 6: Minimum writing speed (MB/s): 7.99 MB/s 1MB = 1000*1000 bytes, SI) 03/31/2019 17:17:22 - 7: Maximum write speed (MB/s): 76.97 MB/s (megabytes per second, 1MB = 1000*1000 bytes, SI )03/31/2019 17:17:22 - 8: Average reading speed. : 57.51 MB/s THIS CARD 03/31/2019 16:19:16 - 5: Average write speed. : 38.86 MB/s 03/31/2019 16:19:16 - 6: Minimum write speed (MB/s): 8.45 MB/s (megabytes per second, 1MB = 1000*1000 bytes, SI)201 9.03.31 16:19:16 - 7: Maximum write speed (MB/s). : 56.98 MB/s (megabytes per second, 1 MB = 1000*1000 bytes, SI) 03/2019 16:19:16 - 8: Average read speed. : 9.47MB/s
