Storing 80 million documents - document format provided

Hypothetical situation:

• Currently have 32GB of RAM setup on my machine
• Goal: Store 80 million documents (~40GB)
• Documents are of the following format:

Key: car_12
Value:
{
    "model":"TSLA",
    "year":"2017",
    "color":"navy",
    "country code":"US"
}

Key: GameConsole::Playstation_5
Value:
{
    "name":"Playstation 5",
    "color":"White",
    "model_id":"98766655"
    "manufacture_date":"20/06/21"
}

Question: What are some technologies/methods/tools you would use to store these documents? (I am not asking for an implementation here)
