What are IOPS?
The acronym IOPS stands for Input/Output Per Second. The number of IOPS a storage device can perform is a factor of: • The block size of the I/O (systems can do more IOPS with small block size transfers); • Data read versus data write pattern • Random versus sequential access patterns (most storage devices do much better with sequential data access instead of random data access … solid state disks perform well with random or sequential accesses).
