[0.04 lb] Man, these things are tiny, considering the storage capacity. I got this one as well as a 150GB Sandisk Flash Drive; both are equally tiny. I love having both an 'A' and a 'C' connector on one drive, with the rotating cover providing protection for the 'C' connector. Performance was excellent! Great price and fast shipping. B&H is the best!

[6 x 4 x 0.4"] Nice Style,capacity,build.

[512 GB] Great mini flash drive. Perfect to transfer images and movies. I used the drive to transfer an iMovie so a student can show his skill to coaches at schools where he is applying.

[512 GB] A dependable Flash Drive, no issues to date.

[512 GB] No cables to mess with. So easy & works great.

[0.04 lb] Seriously, WOW!

This is such a revelation - between the 512 and 256GB models, I'm able to easily back up my iPad pics, videos, or free up storage space on my MacBook Pro (we all know how ridiculous those upgraded SSDs from Apple are!) so efficiently, so ridiculously fast - it's amazing.

I won't give 100% of the credit to the Ultra Dual Drive, but 97% of it's due for sure.

I've owned it for almost three years (256, the 512 for two years) and never a hiccup, lost file, corrupted segment or issues of any kind. I'm so throughly happy with my SanDisk products right now - the Ultra Dual Drive is just so convenient - I have the OWC Go Dock which allows me a few USBA 3.1 options (& MUCH More!) - so between USB C or A, there's always an easy way to offload or upload to the drive.

My Ultra USB thumb drive (512GB) is also rock solid! Little plasticky but never an issue - almost two years with it and my SDDDC2 USB A-C that slides into its case so it won't get damaged rocks too!!!!

I have too many SD and MicroSD SanDisk cards (& CF) to mention other than I've NEVER lost data from one of their cards, not once, hence my review. Just realizing as I am setting up my M3 Max, SanDisk has been a truly remarkable and reliable storage tool regardless of the form factor or amount of storage, connector or cosmetics... I have a 16MB SanDisk card that came with I wanna say the Canon SD400 Elph point and shoot that I believe shot in 480i, if I'm remembering correctly

No problem recommending SanDisk portable SSDs as well, I just picked up a second 2TB from Costco and it's the perfect companion for the expensive laptops we all use now - without the prices of internal unnecessary storage price hikes - and remembering the days installing software from 1.44MB 3.5 floppies - there's no 'slow' to any of their latest options!

Enjoy and keep up the excellent work SD!

[512 GB] Tiny and powerful

[512 GB] Working perfect. Bought several. Very small.... you can lose them easy. But to store perfect.

[0.04 lb] These drives are great. High capacity, good price, and so convenient for transferring files between random machines on the job. A great new addition to my kit.
