What is the reason for needing SSD storage on the server if the database has unlimited capacity? What type of data is stored on the SSD, and what is stored in the database?

SSD (Solid State Drive) storage offers significant advantages over traditional HDD (Hard Disk Drive) storage in terms of speed, reliability, and efficiency. The primary benefit of SSDs is their ability to read and write data much faster than HDDs due to their lack of moving parts and use of flash memory technology. This results in faster boot times, quicker application loading, and improved overall system responsiveness.

When it comes to server performance, SSD storage plays a critical role in ensuring that data can be accessed and retrieved quickly. This is particularly important in the context of databases and server applications, where timely access to data directly impacts user experience and system efficiency.

In a server environment, SSD storage is typically used for several specific purposes:

1. Operating System and Application Files: The server's operating system and core application files are stored on SSDs to ensure rapid startup times and snappy performance when launching applications.

2. Database Components: Parts of the database, such as heavily accessed tables, indexes, and transaction logs, can be stored on SSDs to improve database performance. This allows frequently accessed data to be read and written at high speeds, reducing latency and improving overall database responsiveness.

3. Cache and Temporary Data: SSDs are used to store caching and temporary data, such as web server cache files, session data, and temporary application files. These temporary files need to be accessed and modified quickly, making SSDs the ideal storage solution for such data.

On the other hand, the database itself, regardless of its purported unlimited capacity, is responsible for storing, organizing, and managing the structured data used by the server applications. This includes user profiles, transaction records, product listings, and any other specific datasets required by the applications running on the server. The database provides functionality for querying, updating, and managing this data efficiently, ensuring data integrity and security.

While the database has the capacity to store a vast amount of data, the use of SSD storage on the server complements the database by enabling rapid access to frequently accessed data files, database components, and temporary data. This division of storage allows for optimized server performance and enhanced user experience across web applications and services.

Typically, when hosting a website, the assigned storage space encompasses all the data hosted by the hosting provider: the database contents, files located outside the database, and often even all the emails in the domain's mailboxes.

Isn't it more logical to avoid storing videos directly in the database and instead place them on a disk or an external service, such as YouTube, and then store only the link in the database? This applies not only to videos but also to images and files like PDFs, which are not typically stored directly in the database.

I can tell you about the operations of a hosting company. This type of company focuses on providing services for hosting equipment, data, and websites on its own technical sites.
The paid hosting services are built on high-speed SSD drives, ensuring that your website will load quickly.

That's pure marketing BS-capacity ain't worth squat if your server's choking on I/O like a rusty old rig! SSDs are the big dogs for high-speed gigs - OS files, app caches, and anything needing low-latency juice. Meanwhile, your database is just a fat repo for long-term crap like logs or user junk, probably on some sluggish spinning disk.

No SSD? Good luck with your trash-tier performance and angry users. It's simple: SSDs for the hot, mission-critical grind, DB for the cold, "meh" data.
