This is the first time I use an SSD (2020.01.22)

My first SSD is a Kingston SATA3 120GB A400.
I received this SSD and my current desktop computer as a Christmas gift for 2019.

Today (2020.01.22) I installed an Ubuntu 18.04.3 LTS on it. The first thing I have done on it was a speed test on the SSD. Only the read speed test was successful.

I have made two read speed tests so far.

Average read speed: 281.8 MB/s (100 samples).
Average access speed: 0.13 milliseconds (1000 samples).

Average read speed: 282.6 MB/s (100 samples).
Average access speed: 0.13 milliseconds (1000 samples).

When I try to start a write speed test, the program always gives the following error message: ""Error unmounting /dev/sda2: target is busy (udisks-error-quark 14)".

I currently do not have other experiences with the SSD yet, so this is it for now.
