What’s in the box

  • PNY Duo Link USB 3.2 Type-C Dual Flash Drive


At first glance, there’s not much to the PNY Duo Link OTG USB Flash Drive. Silver in colour and crafted from what appears to be aluminum, it is light and very strong looking. The top of the drive has a hollowed-out loop in which you could feed a small string to attach it to, or directly attach it to, a keyring. Unfortunately, this is not included with the drive. On the opposite end sites a USB-C connector. When pushed to the side, this section spins and you can then access the USB-A connector.

The PNY logo is etched into the flash drive on one side with the words USB 3.2 and 64 (in this case) specifying the USB speed and storage size.

The entire unit is about 2″ long, 1/2″ wide, and about 3/8″ in height.

Ease of Use

The PNY Duo Link is easy to use. Simply flip to the connector you need and plug it into your phone or computer. Once connected, you should be able to easily copy files to and from the drive and your phone or computer. I had no issues using it with a Pixel 7 smartphone and on a Windows 11 PC I encountered no issues as the computer recognizes it as an external drive, as it should.


According to PNY, the Duo Link USB 3.2 Type-C Dual Flash Drive is capable of read speeds of up to 200MB/s with no mention of write speed. As with any other drive we review, I ran it through a few programs on a computer to check read/write speeds while using the USB-C connector.

AS SSD Seq Read241.97 MB/s
AS SSD Seq Write27.56 MB/s
ATTO Disk Benchmark Seq Read (max)233.09 MB/s
ATTO Disk Benchmark Seq Write (max)18.85 MB/s
CrystalDiskMark Seq Read (Q8T1)40.70 MB/s
CrystalDiskMark Seq Write (Q8T1)89.96 MB/s

During real-world testing, I transferred 71 DNG files (a total of 932 MB) from my phone to the drive and then to the computer, both using the USB-C connector. I also repeated the same test with a single 2GB file.

Phone > Duo Link35s2m 20s
Duo Link > Phone11s 30s
Duo Link > PC4s18s
PC > Duo Link38s1m 56s

As you can extrapolate, the drive handles smaller file write speeds better than larger files. That being said, this drive is acceptable when it comes to read speeds but pretty slow when it comes to write speeds.


The PNY Duo Link OTG USB Flash Drive has an MSRP of US$9.99 for the 64GB version, $15.99 for the 128GB version, and $21.99 for the 256GB version. At regular price, the value is definitely there, pretty solidly in impulse buy territory. If you have an iPhone, the company also makes a version with a Lightning and USB-A connector pair.


Even though the PNY Duo Link has slow write speeds, it does come in handy when you want to transfer files from your Android smartphone to your computer. Sure, you can use a cable, but this USB flash drive is small, sturdy, and compact, making it easy to take with you while on the go. Just don’t lose it due to its small size!
