Using FIO for Storage Performance Benchmarking on Linux
Sequential vs Random I/O
Disk I/O operations fall into two primary categories: sequential and random access patterns. Sequential operations read or write data in contiguous blocks, minimizing seek time and maximizing throughput—this is the metric that matters most for traditional hard disk drives. Random operations access non-contiguous locatio ...

Comprehensive VPS Benchmarking: CPU, Memory, Disk I/O, Network, and Load Testing
To evaluate the real-world performance of a Virtual Private Server (VPS), systematic benchmarking across multiple subsystems is essential. Low-cost VPS offerings—especially those priced under $1/month—often rely on aggressive resource overcommitment or aging hardware. While affordability is appealing, raw price alone doesn’t reflect stability, ...
