\n\n

Two limits ruin budget servers: running out of disk and running out of bandwidth. They feel similar \u2014 both are “capacity” \u2014 but they fail differently, cost differently, and demand different fixes. This breakdown quantifies which limit drains your wallet more on a typical cheap plan and how to budget for each.<\/p>\n\n\n\n

They Are Not Priced the Same<\/h2>\n\n\n\n

Disk is provisioned and fixed; bandwidth is metered and variable. That asymmetry drives everything.<\/p>\n\n\n\n

If you’re shortlisting hosts, it helps to compare budget VPS plans side by side<\/a> on how each one meters bandwidth, because the overage rate, not the included allowance, is what bites.<\/p>\n\n\n\n

Disk: The Slow, Predictable Squeeze<\/h2>\n\n\n\n

Disk overage is rare \u2014 most hosts simply cap you. But disk scarcity causes the most painful outages because it happens gradually and silently. A 40 GB plan with a growing Postgres database, rotating logs, and three Docker images can go from 50% to full in two months. When it fills, the database won’t write, PHP sessions fail, and the site returns 500s.<\/p>\n\n\n\n
