We keep everything on our phones these days. While most of us do back up to the cloud, whether it be iCloud, Google, One Drive, or another service, there are times you may want to offload files from your smartphone to your computer. Sure, you can easily connect a USB cable to your computer, but you might not always have one handy.

Design
At first glance, there’s not much to the PNY Duo Link OTG USB Flash Drive. Black in colour, it looks like a portable USB drive without the USB connector sticking out. The top of the drive has a diamond-shaped texture to it. On one of the rounded corners are two small holes in which you could feed a small string to attach it to a keyring. Unfortunately, this is not included with the drive. The entire unit is about 2″ long, 7/8″ wide, and about 3/8″ with the connectors are retracted.
A gloss black piece with the PNY logo and storage size (64GB in this case) printed on it sits in the middle of the drive. This piece is actually a slider. When slides in one direction, the USB-A connector is pushed out of one end. When slid in the other direction, the USB-C connector is exposed.
While the PNY Duo Link looks simple enough, the plastic casing does give me pause. It feels a bit flimsy, and I’d be worried that it may crack eventually, depending on where you store it and how you transport it when not in use. Personally, I’d like to see a bit of a thicker/higher quality shell, even if it increased the price a bit.
Ease of Use
For the most part, the PNY Duo Link OTG is pretty easy to use. Simply slide out the connector you need and plug it into your phone or computer. That being said, once it’s plugged into your phone, you may run into some issues. For example, the Google Files app on the Pixel 5 didn’t seem to let me copy to the PNY flash drive, yet the generic Files app did. It was easy enough to figure out but wasn’t as seamless as it should be. That’s not necessarily the fault of the drive, but it is something to keep in mind. However, on a couple of other devices, the built-in file apps made it easy to copy to and from the drive. On the PC, I encountered no issues as the computer recognizes it as an external drive, as it should.
Performance
According to PNY, the Duo Link OTG Flash Drive is capable of read/write speeds of up to 130MB/s. The packaging also indicates that the write speed may be lower. As with any other drive we review, I ran it through a few programs on a computer to check read/write speeds.
| AS SSD Seq Read | 121.25 MB/s |
| AS SSD Seq Write | 18.33 MB/s |
| ATTO Disk Benchmark Seq Read (max) | 115.58 MB/s |
| ATTO Disk Benchmark Seq Write (max) | 18.85 MB/s |
| CrystalDiskMark Seq Read (Q8T1) | 129.17 MB/s |
| CrystalDiskMark Seq Write (Q8T1) | 17.39 MB/s |
During real-world testing, I transferred 40 DNG files (a total of 486MB) from my phone to the drive and then to the computer. I also repeated the same test with a single 2135MB file.
| 486MB | 2135MB | |
| Phone > Duo Link | 6.5s | 2m 25s |
| Duo Link > Phone | 5s | 33s |
| Duo Link > PC | 4s | 20s |
| PC > Duo Link | 6s | 2m 03s |
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.
Price/Value
The PNY Duo Link USB 3.1 Typ-C OTG Flash Drive has an MSRP of US$17.99 for the 64GB version and $24.99 for the 128GB version. Both are currently on sale for $13.99/$19.99, respectively. At regular price, the value is definitely there, but this handy drive is almost an impulse buy at the current selling price.

Wrap-up
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 and compact, making it easy to take with you while on the go.
