SANDISK 512GB Ultra Dual Drive Go USB Type-C Flash Drive - Up to 400MB/s, Navagio Bay - SDDDC3-512G-G46NBB

It works, My phone storage was 96 percent. I transferred some videos from my phone to the flash drive and freed up storage space to 70 percent. Will be transferring more stuff to it. The size is very small but convenient to carry around. The set up was easy and transfer was quick. It is reliable and will definitely be of great benefit. Price was good. I also like the fact that I can use the C part on my phone and the A part on my desktop. Definitely great purchase

Excellent Product for any device and was strategically purchased for Tesla car with dual port for iphone or android device to show to police officer right there on spot if tesla damages after incident and cant play video. Abosultely beast for Tesla cars and never dropped a single frame in the video due to lowest over heating buffer on USB stick is higher than output birthrate on all cameras writing at the same time. Highly recommend for iPhone, Android, ipad, android tablet or Tesla. Price is the best too for this class and nice data controller. Additionally, Amazon got 2 more stars to make it as 7 stars due that product arrived next day for 5-8 guaranteed for free. Love it a lot. It is smaller than on the image -smaller than half of the finger of the size.

This usb drive is very small but transfers are reasonably quick for a flash drive and the capacity is large. There are both usba-c and usb-a connectors so it works with both my old and new computers. I am satisfied with the purchase.

This USB drive works wonderful. It is a great price with a huge storage capacity. Its small which makes it easy to use.

So far, I've been loving this drives speed and capacity. However, performance has been lacking as i noticed it disconnects rather frequently when used with my tablet and phone. Will updte when/if i find a fix but so far, Not deserving of a 5 star review. Update: Comparing this to other drives. It's slow. Annoyingly so. Writing to it literally takes about 2 minutes before even a small piece of the loading bar comes up. Even reading files takes a while. 🤦🏽‍♂️ Update 2: So I double checked the specs of my laptop just to make sure I'm not crazy. Confirmed the laptop has 2x USB Type C-3.2 Gen 1 ports and the drive is also USB Type C-3.2 Gen 1 and I have never seen this drive even get close to the advertised speeds. Extremely Disappointing! Update 3: I've found that the frequent disconnecting issue was a result of user error. Quick and to the point, Don't have your device in battery saver mode. I've had no issues with connectivity after finding this out. While the older 128gb sandisk pendrive i had didn't have the same issue this one has. I still prefer this as it doesnt get as hot as the older drive while having 4x the storage and slightly (albeit still slow) faster speeds. Worth it!

I bought this to use as a music source in my 2025 Mazda CX90. It was never reliable. I would get maybe one or two songs and then the audio would go silent and when I check my audio source in the menu, the USB device was offline. I'd have to unplug and replug it to get it back. Today, it isn't recognized at all. I even tried it in my phone. Not detected. When I plugged it into a Windows PC, it said there was a problem with this drive and could not repair it. So I am out the cost of this drive. Total waste of money. SanDisk used to be a trusted brand, but it looks like the quality control is nonexistent nowadays.

Decent file transfer speeds for a USB stick. USB-C means great compatibility with modern smartphones. The data has seemed to hold up well over time, very stable

Nice, compact and great backup for vacation. And easy to use.

I bought this to save some space on my phone, when I received it I thought I bought the wrong item because it wouldn’t work with SanDisk Memory Zone on the iPhone 15 Pro. So I thought it may not be compatible with my device. However SanDisk customer support was able to help me navigate using it via the Files App on my phone. It is not compatible with SanDisk Memory Zone on the iPhones, only Androids. I feel that this was the perfect solution for what I needed! It has usb C on one side and usb A on the other so I can use it with my phone and laptop interchangeably. It seems well made and pretty durable. Connectivity is fine once I figured out how to access it 🙃 I love how small it is and that I can put it on a keyring, lanyard or carabiner something to keep it from getting lost.

Easy to use and it works great.

Avevo bisogno di una chiavetta USB compatta per trasferire file tra telefono e computer e questa è perfetta 👍 La cosa più comoda è la doppia porta USB-C e USB normale, quindi posso usarla sia sul PC che direttamente sullo smartphone senza adattatori. I trasferimenti sono abbastanza veloci e riesco a copiare foto, video e documenti in pochi secondi. Le dimensioni sono molto piccole quindi si porta facilmente in tasca o sul portachiavi. Per il prezzo a cui si trova direi che è davvero un ottimo acquisto. Consigliata per chi cerca una chiavetta semplice ma funzionale ✔️

Working as advertised! Would buy again in future!
