The drive in question is a Kingson DataTraveler Exodia M 128GB USB 3.2 Gen 1. I don't often use the 128GB version (I have used it before though) but I've seen the 64GB version in action a few times and its performance compared to other flash drives I've used is reasonable.
I unpacked one of these drives the other day and as the default filesystem is FAT32 I normally quick-format it straight away to exFAT. In my experience the quick format usually takes a second or two. It took several seconds to complete which I found a bit odd. The other thing that was a bit odd was its performance in general but for example it was writing a large PST file (multiple GB) and I would expect a flash drive in this tier while connected to USB 3.0 to be doing at least a steady 6MB/sec, sometimes I'll see a steady 12MB/sec, sometimes higher transfer rates for a while and then settling between 6-12MB/sec. This drive however was writing at say 6MB/sec and then stopping completely for about 10 seconds, then writing at 6MB/sec.
Nothing was posted in the Windows event log to suggest a problem talking to the drive, it wrote the data successfully so I don't have any evidence apart from the unexpectedly poor performance. Any ideas? Are there tests that you run on a flash drive before you start using it?
