Provide a local workspace with many small random reads and writes.
Prioritize low latency without mechanical head movement.
Which medium is generally most suitable?
An SSD has no mechanical seek and generally provides lower random-I/O latency than an HDD. Endurance, capacity, and interface also matter.
Detailed explanation
yumdownloader httpdCorrect. Flash storage avoids mechanical seek and is suited to low-latency random I/O.
yum install httpdIncorrect. Rotational media and head movement increase random-access latency.
yum info httpdIncorrect. Optical media suits distribution and archival rather than frequent random writes.
yum makecache httpdIncorrect. Tape is designed for sequential backup access.
