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 ...
