For those types of requirements, I've found that using a VPS for business projects with SAS drives is a very reliable middle ground. I currently host my company's backend on a HostZealot server using this setup, and the data integrity has been flawless. SAS storage is specifically designed for 24/7 workloads, which gives me peace of mind that our files are safe and accessible. It's a professional-grade solution that offers great uptime and better endurance than your typical consumer-grade drives, making it a solid choice for any serious commercial venture.
