Thanks for your support @Syncromesh,
you are a wise man.
Indeed an SSD can instantly lose its data, which is why I will continue to make backups regularly according to my activities.
That said, I've been using both technologies for years for storage and I've never encountered data disappearing even though I haven't powered an SSD for a few years.
There the situation is different because I'm going to use a high capacity SSD disk (1T) but I took a reliable brand.
This topic is here to objectively show GameGuru users the difference in speed and adaptability of the system.
Thank you again for your information @Synchromesh and I would be pleased to know what the SSD has brought you and how you have integrated it into your working environment. (I think for example of SUBST command usage because I am under Windows 10)
Regarding GameGuru I hope for a faster loading speed of 3d objects for Maps.
