SanDisk Ultra Dual Drive m3.0 128GB — micro-USB and USB-A, 150 MB/s

150 MB/s read128GBmicro-USB + USB-AUSB 3.0

The SanDisk Ultra Dual Drive m3.0 (part number SDDD3-128G-G46) is a 128GB dual-connector flash drive with a micro-USB plug on one end and a full-size USB-A plug on the other, reading at up to 150 MB/s. It was designed to move files directly between an older OTG-capable Android phone and a computer without a cable or a cloud account. Please read the compatibility note below before ordering — the micro-USB connector is the deciding factor. Typically in stock with fast delivery across Cyprus.

Compatibility — check before buying:
This drive has a micro-USB plug, not USB-C. It will not connect to a USB-C Android phone — which is essentially every Android device sold since around 2018 — without a separate micro-USB-to-USB-C adapter. It will not connect to an iPhone or iPad of any generation. Phone use also requires USB On-The-Go (OTG) support, which your phone manual or manufacturer specification will confirm. If your phone has a USB-C port, the SanDisk Ultra Dual Drive Go or the SanDisk Phone Drive for Android is the drive you actually want. The USB-A end works with any ordinary computer regardless.

Best For

✓ Older Android phones and tablets with a micro-USB port
✓ Freeing up phone storage without a cloud account
✓ Moving photos and video straight from phone to PC
✓ Everyday file transfer on any USB-A computer
✓ Keeping a spare drive on a keyring
✓ Households still running older Android hardware

Key Features

 
Two connectors, no cable
A micro-USB plug for OTG-capable Android devices and a full-size USB-A plug for computers, joined by a swivel body that shields whichever end is not in use. There is no cap to lose.
 
150 MB/s read at this capacity
SanDisk publishes up to 150 MB/s read for the 32GB to 256GB models; only the 16GB model is rated lower, at 130 MB/s. Write speed is not published by SanDisk, and we do not print a figure the manufacturer has not stated.
 
USB 3.0 on the computer end
The USB-A connector runs at USB 3.0 speeds on a USB 3.0 port and falls back cleanly to USB 2.0 on older machines. SanDisk has not restated this family under the newer USB 3.2 Gen 1 naming.
 
Compact and light
At roughly 30 x 25 x 12 mm and 5 g, it takes up almost no room in a pocket or bag, and the integrated loop takes a keyring or lanyard.

Frequently Asked Questions

Will this work with my phone?
Only if your phone has a micro-USB port and supports USB On-The-Go. If your phone charges with a USB-C cable, this drive will not plug into it. Almost every Android phone released from about 2018 onward uses USB-C, so check your charging port before ordering.
Does it work with an iPhone or iPad?
No. Apple devices use either a Lightning or a USB-C port, and neither accepts a micro-USB plug. There is no adapter arrangement we would recommend here — buy a drive built for your device instead.
What is the difference between this and the Ultra Dual Drive Go?
The connector. The Dual Drive Go has USB-C in place of micro-USB and reads faster at the same capacity. The m3.0 is the older micro-USB generation, kept for people who still run micro-USB hardware.
Is SanDisk still making this drive?
It is a legacy product. SanDisk has published no end-of-life notice, but every capacity now shows as unavailable to order directly from SanDisk. We list it because micro-USB hardware is still in use; if you have a USB-C phone, choose a current model instead.
Singular Expert Insight
Buy this one deliberately, not by accident. The Ultra Dual Drive m3.0 is a good drive that answers a question most people stopped asking around 2018, when Android moved to USB-C — and the single most common return on this kind of product is a customer who ordered a micro-USB drive for a USB-C phone. If your phone charges with USB-C, look at the Ultra Dual Drive Go or the Phone Drive for Android in our USB flash drives range instead. Where the m3.0 still earns its place is a household with older tablets or a phone kept in service, and as a plain USB-A drive for a computer it is entirely current. If you are moving large video libraries rather than the odd folder, a portable SSD from our external SSD range will be several times faster for not much more money.

Buyer’s Guide

Buy it if

Your phone or tablet has a micro-USB port with OTG support, and you want to move files between it and a computer without cables, cloud accounts or a card reader.

Skip it if

Your phone charges with USB-C, or you have an iPhone or iPad. The plug physically will not fit, and an adapter is a poor answer to a problem you can avoid by buying the right drive.

Also consider

The SanDisk Ultra Dual Drive Go or the SanDisk Phone Drive for Android for USB-C phones, or a plain Ultra Flair if you only ever use the USB-A end.
