SANDISK - Ultra Dual Drive Luxe 128GB USB 3.1, USB Type-C Flash Drive - Silver

This is a great little flash drive I keep on my keyring at all times. It's metal, so it's durable, jangling around in my pocket and has a nice sized capacity. And I love that it's dual USB C & "regular" USB. Very handy.

Needed a solution to save some photos from my iPhone to save space rather than to purchase more space. This USB drive is very user friendly, especially for a senior like me. It also is good looking Sometimes I carry it on a strong cord around my neck so if I want to look at a photo or video , I just plug in iPhone and view photo or video within seconds of connecting.

No complaints using it both USB-A and USB-C, speed is fine, nothing spectacular, but what I expected. Takes a bit of a beating in my pocket with my keys, but so far haven't had any issues. Have had the USB-C end get stuck in other pocket items occasionally, but it doesn't seem to have caused any damage yet. I try to keep it flipped so the USB-A end is facing out, but it gets pushed around constantly. Sturdier than the plastic version.

Disappointed with the performance of this drive tremendously. Out of the package, plug into a Windows desktop it is formatted at FAT32-- No file bigger than 4GB can be written onto it. Terrible. Quick fix; just format it to exFAT so it can be used on most OS' and have no file limit. File transfers are SO SLOWWWW though that it makes this a chore to use. Moving 7 files, ranging from 1.85-4.5GB each in size, 19.5GB total, it took over 15 minutes to do! It started at around 64MB/s and after about 40 seconds TANKED and just lingered the rest of the way at 22-23.1MB/s. Unacceptable for a drive in 2021!I was using the USB-A side, into a USB 3.0 port, as I don't have a USB-C port on my case at the front and it was easier than reaching around back for the USB-C on rear of motherboard. Even still, old thumb drives I have had for over 5-6 years perform better than this one! The ONE single saving grace is the usefulness of having both USB-A and USB-C so you don't need to worry about adapters or dongles. The metal casing, while a premium touted feature, makes this drive very, very warm to the touch. Attached a cropped image of the transfer window, and this was about 9-10 minutes into a transfer after doing the format to exFAT to copy two files over 4GB in file size. The convenience of this may not be enough to overlook the absolutely terrible performance for a thumb drive, I may return it in a couple days. I'd rather get one that performs as it's advertised and I pay for, as I'm sure cheaper 3.0 USB drives will perform better than this. 2/5 for quality, as it's nice design, but gets warm to touch and the swivel isn't locking as smooth as I would imagine. 1/5 on value because performance is terrible in transferring files, and ease of use is 1/5 because out of the box it imposes file limits by being FAT32, and while it's an easy fix, I imagine not everyone knows to format it to exFAT out of the box as they will just plug it in and use as it is. Not recommended!

Yhis usb drive passed a validation test with third party software faster than others. Drive also has standard and type c usb for good connection versatillity with different devices.
