I looked online for a benchmark for one of these drives before buying it but came up empty. Here’s CrystalDiskMark after running it with default settings. The drive is connected via USB 3.
Its part number is PA5307A-1MCL and out of the box there is one empty FAT32 partition.
I got an PA5307A-1MCR (Red) and had different results… could you have tested on a USB 2.0 port?
