Manufactured: in China
USB flash drives were mainly used to store temporary files, and move them from one place to another. They made our lives much easier but over time our needs have changed and also technology has moved forward, from the typical type A, to micro USB, and now to type C that on paper looks to be very promising, for both features and speed.
Lexar has three USB flash drive that all share the C20 model number but with different last letters. They start with the C20i that as you might have guessed is aimed at Apple users. Next we have the C20m that has a micro-USB connector, and finally the C20c that features a type-C connector. The common factor for all three drives though is the type-A connector, and they are all available in capacities of 32GB, 64GB and 128GB. You can find out more about them on the Lexar website, simply by clicking here.
Lexar has sent me the C20c USB3.1 Gen1 64GB device to review, so let’s start this review by taking a look at the drive and its packaging.
Lexar C20c 64GB USB3 flash drive, packaging and specifications
Let’s take a closer look at the packaging of the Lexar C20c USB3.1 flash drive.
From the front of the package we can see the drive. The main attraction here is the 3-in-1 USB, which means that the drive can be used with a machine that supports Type A, also Type C, and it can charge our device. Read speed is up to 150MB/Sec but there’s no information on the write speed.
A look at the Lexar C20c USB3.1 flash drive, its size is 15cm (which is just less than six inches).
This is how the drive is stored, and this way it can be used, with the type A port. It saves a lot of space, and build quality is also very good for both connectors and cable, which should hopefully last for a long time.
Let’s take a look at the specifications for the Lexar C20c as they appear on the website.
We can see the main features and specifications of the Lexar C20c, and also that the drive is a USB3.1 Gen 1 and reaches read speeds of 150MB/sec and the write speeds of 60MB/sec for the 128GB drive, although there’s no info on the write speed of the other two drives. It has a three-year warranty and you can find any extra info you need at this link.
Before I start testing the Lexar C20c flash drive let’s find out what’s inside using the Flash Drive Information Extractor tool.
Here we can see that the Lexar C20c uses the Silicon Motion SM3269 controller. The tool does not provide any info on the memory chips but it will be safe to say that inside we will find chips that are manufactured by Micron.
Now it’s time to start testing the Lexar C20c and see what speeds it can achieve in real world tests, and I will start with a few synthetic benchmarks.
Now let’s start testing the drive with the NTFS file-system…
