It's a very fast device and works really well. The user is advised to tie a lanyard to the device so as not to lose it because of its very small size.

This works both on macOS (Yosemite all the way up to Sonoma) and Windows (10, 11). I am able to easily transfer and work with (print, edit) files on this flash drive no matter which system I am using. I have also used this drive while plugged into my iPhone 15 and it works just fine. Using the Files app and browsing to the flash drive, I can see and open the files on it with no problem. The entire device itself is quite small and portable, so it fits in any pocket, pouch, or on any keychain without taking up a lot of space.While I have only been using it for a short while (three weeks), it has always been available and reliable, with no hiccups or complaints from either Windows or macOS about the drive not being visible/readable/ready.The only reason this is not a 5-star item is the physical design. I like that you can have either side/connector (USB-A or USB-C) out/open by spinning the flash drive, but that also means that whichever side is out is exposed. This device DOES NOT come with any kind of dust/protective cover for either connector. For that matter, the side that is not exposed isn't exceedingly well protected either, but it is better than nothing. I would like it if the device came with protective caps for the connectors or allowed you to control exposure of the connector ends.Shy of that one issue (lack of dust covers for connectors), this is a very good flash drive.

love it, holds all my pics in one place.

Having both USB-A and USB-C connectors, this small, high-capacity memory stick is perfect for quickly transferring data from an iPad or smartphone to computer.

Easy to use but did not come with a manual. Once plug into a device, you will learn that you have to install Sansisk app to use the thumb drive to get transfers from your phones or laptops.

I rarely write reviews, but sometimes it’s best to share your experience so others can make an informed choice.This 512 GB flash drive is tiny and quite useful because it has both USB-A and USB-C connectors. I have to go back and forth with laptops and desktops that have one or the other and it’s very convenient to use this drive; it holds a lot and will plug-and-play in older and newer machines. Because it’s so small, it’s easy to carry in a pocket or wallet, and with the capacity, will hold a decent number of files, pictures, videos, etc. Except for the USB-C connector (which is metal), the entire housing is plastic; very lightweight.The most prominent characteristic of usage is that it’s the slowest flash drive I’ve ever owned (going back about 15 years), regardless of capacity or connector. Using either the the USB-C or USB-A ports, opening a window just to look at the contents can take 15 seconds to display what’s on it. Music files sometimes have dead spots (gaps) while the song plays, as the file loads to cache. A 15 GB copy takes roughly an hour. If these types of operating times aren’t satisfactory for your typical usage, it might be best to consider alternatives.
