- ✓ Brand New — Retail Packaging (sealed)
⚠️ Discontinued line — limited stock remaining.
The full phone, the “storage almost full” warning, the video that will not send — the SanDisk Ultra Dual Drive Go 512GB exists for exactly that moment. Flip the swivel cover one way and the USB-C connector plugs straight into your phone or tablet; move the files across, flip the cover the other way, and the USB-A end plugs into any computer made in the last two decades. No cables, no cloud subscriptions, no waiting for uploads. USB 3.2 Gen 1 keeps transfers at up to 400 MB/s, the free SanDisk Memory Zone app can back your phone up automatically every time you plug in, and the keyring hole means the drive lives with your keys instead of a drawer. SanDisk has since discontinued this much-loved line — this is brand new, sealed retail stock, dispatched from our UK warehouse while it lasts.
Two Connectors, One Stick
Phone to Computer, No Cables
A USB-C connector on one end and USB-A on the other means the Dual Drive Go speaks to both halves of your life: the USB-C phone or tablet in your pocket, and the USB-A laptops, desktops, TVs and car stereos everywhere else. Offload holiday photos from the phone at the airport, hand the same stick to someone with a ten-year-old laptop, plug it into the TV for a film — one drive covers all of it, with no adapters and no pairing.
USB 3.2 Gen 1 Speed
Up to 400 MB/s Reads
Moving a phone full of photos over Bluetooth or cloud upload takes an evening; over USB 3.2 Gen 1 it takes minutes. Read speeds up to 400 MB/s make offloads and transfers quick in both directions, and the free SanDisk Memory Zone app for Android turns the plug-in moment into an automatic backup — photos, videos, documents and contacts copied across without you thinking about it.
Built for a Keyring
Swivel Cover, Go Anywhere
The integrated swivel cover protects whichever connector you are not using — no caps to lose — and the reinforced keyring hole means the drive travels with your keys. At 6.5 grams it disappears in a pocket. iPhone 15 and newer (USB-C) owners can browse the drive through the Apple Files app; Android users get the full Memory Zone experience.
Right choice if you…
✔ Keep running out of phone storage and want a no-cloud fix
✔ Move files between USB-C devices and older USB-A computers
✔ Want automatic phone backups every time you plug in
✔ Carry your storage on a keyring rather than in a drawer
✔ Want the classic Go line while sealed stock lasts
Look elsewhere if you…
✖ Want an all-metal build — see the Ultra Dual Drive Luxe, also at maibo
✖ Need hardware encryption or password protection
✖ Want to record video directly to the drive from an iPhone

Frequently Asked Questions
Does it work with iPhone?
With iPhone 15 and newer (USB-C models), yes — browse and copy files through the Apple Files app. Direct video recording to the drive is not supported. Older Lightning iPhones are not compatible.
What is the difference between the Go and the Luxe?
Same 2-in-1 USB-C/USB-A idea. The Go is the lightweight 6.5g plastic version with swivel cover; the Luxe is the all-metal version. Both are genuine SanDisk — we stock both at maibo.
Do I need software to use it?
No — it works as a normal flash drive on Windows, Mac and Android out of the box. The optional free Memory Zone app adds automatic backup on Android.
Why is it marked discontinued?
SanDisk has retired the Go line from production. Our units are brand new, sealed retail stock — once this batch sells through, restocks are unlikely.
Is this a genuine sealed unit?
Yes. Genuine SanDisk Ultra Dual Drive Go (SDDDC3-512G-G46), brand new in sealed retail packaging, covered by SanDisk's 5-year warranty, dispatched from our UK warehouse with tracked delivery.
