Lexar C20c 64GB flash drive review – The three in one solution

Real world tests


Benchmarks are great, as they can give a
very good view of how the drive can perform when it’s pushed to the maximum. Unfortunately,
they only tell part of the story, and the rest you have to find out when you’re
using the drive for everyday tasks. I’ve therefore decided to perform three
simple tests that almost everyone does, so that I can get a better view of the
performance of the drive.  

For this test I will be moving all the test
files from a RAM disk to the tested USB drive, and vice versa. Below you can see
the results.

MP3

I will start my tests by performing a
simple copy of 1.36GB of MP3s. You can see the results in the graph below.

are some previous results, which are only for reference purposes.

The first test for the LexarC20c is good, write
speed topped out at 52MB/sec and the read speed maxed out at 122MB/sec.

Pictures

For the next test I will copy 3377 assorted
picture files with a total size of 2.56GB, so let’s see how the drive performs.

Here we can see that the Lexar C20c does
not like relatively small files, but it’s able to reach a maximum write speed
of 18MB/sec and the read speed was 99MB/sec, so there is also a drop in the
read performance.

Movie

Before I finish my tests I’ll copy an MKV
file and an SRT file, a very common task that most of us do to transfer movies.
The two files have a total size of 3.46GB

wherewith large files the Lexar C20c was
able to achieve its maximum performance. Write speed topped out at 80MB/sec and
the read speed was 137MB/sec, both of which are very good.

ISO

Closing my four main tests, I will copy an
ISO file with a size of 7927MB, from the RAMDisk to the destination and vice
versa.

Moving on to even larger files we can see
that Lexar C20c continues to deliver very good results, 81MB/sec for the write
and 134MB/sec for the read part of this test.

Small Text files

In one of my previous reviews I was asked by
a user to do a test with proper small files. So I went ahead and put 48128
files in one folder and ran some tests with a few of the latest USB flash drives.
I personally don’t feel that this kind of abuse will happen on a daily basis,
and the result of this test will not have a very big impact on my rating of the
tested drive, but it’s a good way to separate the men from the boys and fun to
do, even if it takes a lot of time.

First here is a screenshot to give you an
idea of the actual size of all these files and further below you can view the
results from this test.

2000 seconds is a lot of time. Most USB3
flash drives don’t like writing that many small files and the Lexar C20c is no
exception to this trend, however the read result was good and the drive was
able to achieve 13Mb/sec.


Anvils Benchmark (100% incompressible)

Below you will find a graph showing the
performance of the Lexar C20c against all the other USB3 flash drives that I
have tested. All the drives were connected to the Intel USB3 ports.

In this final extra test, we can see that
the Lexar C20c achieves the speeds that we saw in the previous tests. A good
read speed, but a higher write speed would have been welcomed.

Now let’s close this review…
