Initial Thoughts are mixed...
This is a re-write so the details will be different.I wanted to expand the space in my Raspberry Pi to support a few LXD containers. Currently I am running a 32GB and 64GB without any issue. So I picked up the 128GB units.When I insert them into my Mac to format all five units show 125GB of storage. That was the first flag of notice for me. The drive was formatted with the LiveOS image and it seemed to take a little bit of time. Nothing major but it was fine. I then inserted it in the Raspberry Pi and booted and the time it took to setup was way longer than expected. I ran commands to update the OS and it took a much longer time than expected. I then took a second flash drive and formatted it (I had flashed the LiveOS onto it already) with APFS and it errored out but the drive looked fine. I copied files onto the drive and it took a really long time. I flashed it again with APFS and it once again errored out and the copy took a really long time. I then flashed the drive with EX FAT and the files copied fine. I flashed it again with EX FAT and no error and files copied fine. I then flash the LiveOS onto the drive again and once again the performance declined on the second drive the same as the first drive.The random IO on the drive for LiveOS use is not good, but if you format it with the right format the drive does good with file copy / transfer performance.I came back and read other reviews and seen others have similar experience already with these drives in my use case scenario.Hopefully this helps someone before purchase to make the right decision based on their use case. Drive works great with EX FAT format and not so good with LiveOS usage to boot off a drive.The packaging the drives came in was weird also. They arrived in a unmarked box with a label identifying the drives and bubble wrap.

When it comes to portable storage, SanDisk should be your only stop. This little device boasts half a terabyte of storage which is amazing for its size. Great product.

I purchased the USB in February 2019 and it failed in Nov 2019, ten months hmmm. From new it required far more pressure to insert then my other USB drives and the housing became noticeably warm when in use. At that point, I should have sent it back but instead dismissed it as the consequence of its small architecture and poor manufacturing tolerances. After less than fifty applications the housing broke but more annoying the stored data became unrecoverable. I have several full size SanDisk and other maker USB drives and none have exhibited the above noted concerns or failures. Unfortunately four days ago my wife purchased the SanDisk 256 model and it also requires more insertion force than should be required, foreshadowing dear reader. Would I recommend this product? Absolutely not. Will I continue future Sandisk purchases? Probably, but not their miniature series. SanDisk, if you wish to offer me recompense, I will gladly include your response as an appendix to my review.
Cheers E
Update: Nov 25, 2019
The day after submitting my Amazon review I contacted the SanDisk warranty department by email requesting recompense as the USB was less than 5 years old. I provided them a copy of my Amazon purchase order and the next day I received a follow-up email from SanDisk® Global Customer Care stating SanDisk did not have a 128gb replacement in stock (in the warehouse) but would I settle for two 64gb instead to which I replied, yes. Within a day or two I received another SanDisk email this time different in tone. It referenced my Amazon.com review and included the following highlighted in blue, "Note: Refurbished, physically damaged or non-authentic products are not covered by SanDisk warranty". The email also included an RMA (Return to Merchant Authorization) but no mention of the previous replacement offer.
So what happened, a SanDisk employee armed with my Amazon purchase receipt trolled the Amazon.com website and located my review. Upon reading it they identified I had mentioned the USB casing had broken and presto SanDisk feels the warranty claim is disqualified, hence the blue highlighted script. To appear as a good corporate citizen they now offer me an RMA (Return to Manufacturer Authorization) so we can go through the process. Okay I will, with the clear understanding that I intend publish every SanDisk response regardless of the outcome.
Other critical Amazon reviews about this product identify similar concerns, it runs hotter than a full sized USB, it is a tight fit especially in USB 3.0 ports, the housing cracks and this device prematurely ends in software/hardware failure. See a similar Amazon.com posted review provided by Gennaro M. on March 15, 2018. It is one of the many provided by dissatisfied consumers. My complaint, like those generated before me, does not originate from consumer misuse, abuse or accident but by product failure and warranty issues.
Stay tuned for SanDisks response which I intend to publish when I receive it.

On 2019.11.27, I received the following email from James P.. a SanDisk® Global Customer Care rep, "Thank you for writing back to us. Please be informed that the statement which was sent in the e-mail is a standard statement which we use in all automated RMA approval e-mail for letting customers know that Refurbished, physically damaged or non-authentic products are not covered by SanDisk warranty. Also we understand that you are not very satisfied with the model of flash drive which you were using earlier i.e. SanDisk® Ultra Fit USB 3.1. Therefore we would like to offer you an alternative product i.e. SanDisk® Cruzer Glide USB 3.0 128GB (SDCZ600-128G) in replacement. Please suggest if you are agreed for the alternative model".
I agreed to accept their offer and on 2019.12.10 I received without cost to me a full size USB SanDisk® Cruzer Glide USB 3.0 128GB (SDCZ600-128G) delivered to my door. In the end SanDisk® or the parent company Western Digital Technologies Inc honored the warranty. I will continue to use SanDisk® as long as the honor they warranty. However I would not again purchase or recommend this specific product the SanDisk® Ultra Fit USB 3.1.
