For a review of MicroSDWow. $306 for a 1T card? Amazon SanDisk card is $140 for 120mb/sec and $167 for 160 mb/sec. Is that card worth double the price?

Micron c200 microSDXC Card Performance
In this review, we will compare the 1TB Micron c200 microSDXC UHS-I card with the following:§ 1TB SanDisk Extreme
§ Samsung Evo Plus
§ Adata Premier
Using our Lenovo ThinkStation P920 Workstation Consumer Testing Platform, we measured 2MB sequential transfer speeds from the Micron with 92.4MB/s read and 86MB/s write, close to the quoted speeds. The 1TB SanDisk showed top results of 160.13MB/s read and 100.93MB/s write, while the Samsung posted 92.15MB/s read and 84.62MB/s write. The Adata measured on the lower end with sequential read speeds of 60.6MB/s and sequential writes of 33.41MB/s.
When comparing random large-block transfers, the Micron cc200 card showed a solid 88.8MB/s read and 83.2MB/s write. In comparison, the SanDisk reached 113.89MB/s read and 60.29MB/s write, while the Samsung posted 85.73MB/s in read and only 1.16MB/s write. The Adata card was able to reach 50.58MB/s read and 29.81MB/s write.
For Random 4k transfers, the Micron card hit an impressive 2,154.5 IOPS read 1,158 IOPS write. The SanDisk measured 1,215.85 IOPS read and 560.72 IOPS write, while the Samsung posted 1,480 IOPS read and 420 IOPS write. Here, the Adata performed well, hitting speeds of 2,971 IOPS read and 1,190 IOPS write
We also put the card through the Blackmagic disk speed test using a current generation MacBook Air, which showed 90.2MB/s read and 83.2MB/s. The SanDisk card posted 156.3MB/s read and 99.2MB/s write while the 512GB Samsung was able to hit 90.3MB/s read and 77.8MB/s.
