I like this memory usb , very small to put in your pocket. I trasfer my files very fast no problems

The file type used on this drive will not allow you to copy files larger than 4 gig. What genius thought that would be a good idea in a 500 gig drive? I had to contact support multiple times before they told be the drive needed to be reformatted to be used.

The SanDisk Ultra Dual Drive Go 512GB delivers exactly what it promises: high‑capacity, high‑speed storage in a compact, dual‑connector design. The 512GB capacity provides plenty of room for large files, whether you're storing photos, videos, VM images, or OS builds. The dual‑purpose swivel housing is practical and well‑engineered. Both the USB‑C and USB‑A connectors stay protected when not in use, and the integrated key‑ring hole makes it easy to carry without worrying about damage. Performance is where this drive stands out. With read speeds up to 400MB/s over USB 3.1 Gen 1, transfers are consistently fast and sustained, not just short burst speeds. It’s also fully backward‑compatible with USB 3.0 and 2.0, which is helpful when moving between older systems. I used this drive for a persistent live Kali Linux installation, and the experience has been excellent. Boot times are quick, applications load smoothly, and overall responsiveness feels close to running the OS from an internal SSD. For a compact flash drive, that level of stability and speed is impressive. The SanDisk Memory Zone app adds optional automatic backup for photos, videos, documents, and contacts (installation required), and the drive works with iPhone 15/Pro through the Apple Files app. Just note that it doesn’t support direct video recording from the iPhone. Overall, this is a fast, reliable, and versatile USB‑C/USB‑A drive that handles both everyday storage and more technical workloads without issue.

Dual works great. Convenient. Easy to use. It fits any computer. Holds tons of information.

What's to say except that this SanDisk Ultra Dual Drive Go 512GB does what you expect - expeditiously. The basic review follows BUT NOTE THE LATTER PART OF THE NAME OF THIS DRIVE :: USB-A/USB-C Flash Drive. You can plug into a C port, drive slot, whatever you call it, and read or write data AND THEN flip it around and plug it into an A slot to write or read the same data. PERFECT to be a GO drive. I have formatted it ExFat to move files from Windows into Mac OS Journaled and vice versa. I am about to move all the data off one Mac Studio onto an upgrade Mac so it is now formatted Mac OS Extended (Journaled) to receive data from APFS. I moved 66GB from Mac MAX 2 Studio in 10, 11 minutes which was ok. I say that because I moved about 33 GB of pics from Mac APFS to ExFat and it took all night - also on a different, slower drive. It also makes sense that this GO drive is 512GB because it is for transition purposes. S maller may be cheaper but more trips. I have used San Disk before they were associated with WD (I am a WD fan) and I can sincerely say that I continue to be pleased with SanDisk. An old time name that goes waaayy way back tried this 'GO' concept before but they failed terribly. VERY WELL DONE SANDISK.

These are great for storage and/or transferring files, especially from phone to laptop or vice versa. The small physical size makes it easy to drop in your pocket or your laptop case. Good deal when you get them on sale. I have a couple, each for specific types of files (photos, personal, work, etc.)

THE SANDISK - ULTRA DUAL DRIVE GO 512GB FLASH DRIVE was a great purchase. Quick, efficient and easy to use. I recommend it to anyone looking to transfer or store data quickly and easily.

So far, the product works great! I love the ease of use and the fact that I can use it for USB-C or USB-A inputs. Make the limitation of certain devices feel nonexistent.

I had to remove more than 30K photos and a few thousand documents from an old computer. This flash drive is holding it all and I have still have tons of space for more. Great product!

Works great! Lots of storage and convenient to use. Makes backing up old computer easy peasy.

Works as intended. Easy to use and understand. Definitely likes that it has both USB and type c connection.

Perfect! Small, transportable and a tiny fraction of the size of the last drive i bought (same number of gigabytes). Great product

This flash drive is tiny, but it's fast and very user friendly with two types of USB connectors. While it doesn't take up much room, that is also the one downside. You need to make sure you attach a keyring or something to it or the risk of losing it or overlooking it is fairly high.

Works great. Lots of storage. I put 10,000 photos on it and still have room.

Compact yet capacious, the 512 GB SanDisk Ultra Dual Drive Go delivers excellent on‑the‑go versatility with its reversible USB‑C and USB‑A design. It offers plug‑and‑play simplicity—perfect for transferring large photo libraries, videos, or backups across Android phones, tablets, and legacy PCs—and consistently hits up to ~400 MB/s read and ~350 MB/s write speeds, making file transfers quick and smooth

Love the compact size, the storage space and the quick retrieval of data from it.
