Hey Alan!

There goes 42 minutes I'll never get back.

Just a tad under 4x faster but still +10 minutes of my life gone to testing el-cheapo flash disks.  However one more test as the Leexar has a USB-C male plug on the opposite end of the pen drive.  Is there a difference?

Slightly faster but nothing to write /home to the mothership about.

For the record the sata ssd on both the type a and c produced the same result at 395 MB/s transfer rates, which compared to the above rates is astronomically superior if one ignores the cost differential.
