Hey there, @Ezenia!
I totally agree with @timeconsumer regarding the health state. Everything looks pretty good according to these benchmark results. I'd advise you to download the SSD's brand-specific utilities as well and use them to monitor the health and SMART status as well. These tools can also help you update the firmware, if needed in the future.
Always remember to backup your files! This is how you will avoid any potential data loss in the future! Just make sure that you create a copy, as moving data from an internal drive to an external one is not considered a backup, unless you have a duplicate/copy stored on a different drive.
Best of luck!
