Disk I/O
- Read: Reading data from disk involves reading data blocks sequentially or randomly from disk storage. While sequential reads can be relatively fast, random reads can be slower due to disk seek times.
- Write: Writing data to disk involves physically moving the disk head to the correct location and waiting for the disk to rotate to the correct position. This process is slower than reading data from disk.
Is the read performance slow or the write performance?
Read Performance is often faster than Write Performance. Below are the reasons why Read Performance is faster than Write Performance
