Acer Chromebook C720 SSD Upgrade To MyDigitalSSD M.2 (NGFF) 128GB SSD – Worlds Easiest Upgrade


If you look at the image below, you will see a screen grab of the Disk Management Interface of the system we tested the Kingston 16GB M.2 SSD on.  The first is our main drive and the second the Kingston M.2 SSD with the operating system intact as if it were new.


Looking at the standard Chromebook SSD, we can see that there is 14GB available after formatting, and then only 10.76GB after the OS backup and other files are included.  The difficulty with this is that a SSD slows as it get full and, well let’s face it…a few piks, movies and songs and this SSD is full.  Let’s take a look at performance and a realistic example of how it is affected. The first test we will look at is ATTO which will give us an idea of how these SSDs match up according to specs:

As we can see by these tests, the performance of both SSDs seems to be closely matched.  This is not the case though as ATTO tests with highly compressible data only and not compressible data, that of which photos, music and media are comprised.  We are able to sort out the differences when testing in incompressible data because this type of data is more difficult to write than the former.  Let’s look at our Crystal DiskMark results:

The MyDigitalSSD SC2 M.2 SSD result is left with the Kingston SSD on the right and we can see the difference in SSDs now when we test with incompressible data.  Will you visibly see this in your Google Chromebook?  Not initially but these slow downs will become visible as the SSD fills.  Do you remember the original remaining capacity of the standard SSD being 10GB total available space?  AS SSD is a benchmark program that will stress both SSDs a bit more.  let’s take a look at how the Kingston fares now:

In examining both SSDs, we can see that the MyDigitalSSD SC2 is clearly a higher performing SSD all around, solely by its performance when testing with incompressible data (media files).  As much as performance may be a consideration, however, we need to consider that any system with only 16GB of memory is doomed for anyone who plans to save anything on that SSD.  Just like you and I, an SSD needs an adequate breathing space to perform at its best and upgrading this system with a higher capacity SSD will improve capacity, as well as guaranteeing long-term performance of the system.

  1. Got my Acer C720-2800 the day after it was released and I did this upgrade soon thereafter. I also fixed the rattle in the touchpad when I was in there. My tech abilities are high, but this is an incredibly easy upgrade. With OS re-installed and all of my apps downloaded I believe I was left with 106GB of space. I have not had any issues with the drive.

  2. Step Two install your favorite Linux (OpenSUSE with i3) and have fun.

  3. An excellent step-through but baffled by why anyone would want to put a larger SSD in a machine designed to store files in the cloud (and which comes with 100GB of online storage).

    The performance boost in real-world use will be minimal because the OS is highly optimised for web apps which use the cloud.

    Good walk through though.

  4. Could the same upgrade be done to the chromebox?

    About to do this with my C720P 4gb Ram (European model). Dual booting it with Linux, to play GoatSimulator… Oh and other stuff too.

  6. I’m looking at doing this upgrade to my i3 c720 3405. I can’t decide which one of the mydigitalssd cards to purchase between the superboot or super cache 2. Other than some software that comes with the cache version which probably can’t be used on chrome os or would help it much. Is there any difference between the two other than software?
