We will be using persistent disks when we need reliable and affordable storage with consistent performance characteristics. With standard HDD persistent disks, they are efficient and economical for handling sequential read and write operations. Random IOPS are not optimized on persistent disks.
At the same time, SSDs are used for high rates of random input/output operations per second. These are designed for single-digit millisecond latencies, but often they are not used for archival purposes.
We can use local SSDs that are suitable for temporary storage. SSDs can also be used when we need fast scratch disk or cache, processing space, or low-value data.
