Customer Ratings & Reviews

The SanDisk Ultra 512GB USB 3.0 Flash Drive is super fast and holds a huge amount of data. Transfers are quick, even with large files, and the retractable design is a nice touch — no cap to lose. Perfect for backups, videos, and everyday use. Great value for the storage size!

I bought this USB flash drive to expand storage on my Insignia Fire TV. (Found out later that the TV accepts a maximum of 64GB for flash drive expansion.) I'm now using this 512GB flash drive to back up my laptop. Really fast, small and convenient. Highly recommend!!

Impressed with the SanDisk Ultra 512GB USB 3.0 Flash Drive! It's compact yet spacious, perfect for storing my entire digital life. Quick and reliable transfers make it a must-have accessory for work or play. Highly recommended!"

Very easy to use. It has a ton of storage. I moved nearly everything from my work computer of 10 years to store it on this.

Compact and fast download and upload capability at a reasonable budget. It fit the requirement for a backup of my laptop in service.

I can't confirm how much space it holds; I'm just using it for storing videos and the write speed is good, read speed is very fast, no problem watching the videos I saved on it. Small and I like that the usb part is retractable. Hard plastic case seems sturdy. You can add a lanyard with the hole at the end.

My wife loves this memory stick. It has helped us save some very important things that we don’t want to lose should our hard drive crash.

Great buy. I bought 512GB flash drive because it was on Sale and 1TB was more than 2x the price. It works great although the set up instructions on tge Web are hard to follow because the site covers all products by Westgate who own Sandisc.

It does exactly what its intended for; i'm still using it with no problems.

Pretty good with holding a ton of files. Would use for personal Files.

One can't have too many thumb/flash drives. Recently purchased this at one of Best Buy's sales event prior to Christmas 2023.

I needed a new USB and this one works perfectly. I like being able to retract the usb part for protection.

It was helpful with what i needed transferring important data from my mother old phone to mines so that I don't lose any memories of her.

was easy to use and worked great for storing photos on

SanDisk - Ultra 512GB USB 3.0 Flash Drive - Black It is a USB and fast I recommend it

Great for Storing a lot of Videos & Music & Photos.

Need a simple usb drive well this should work for you

Works good a little pricey but i was in a pinch so got it

I love this and i use this to organize storage and to transfer them safely to other computers.

I couldn't get Ventoy to partition this USB drive into 2 parts, one for Ventoy bootable code and the other for iso files (in my case F: and G:) I've done this activity before, now setting up boot recovery for my daughter's college computer. After some fussing I decided to run FakeFlashTest on it. It has a chunk of corrupted blocks that make it unpartitionable for Ventoy work. See image of FakeFlashTest resuts
