In computing, communication between two processing systems is based on Input-Output operations. For example, input operations are the signals/data sent from a CPU or another type of controller towards a storage device. While output operations are reading and sending data from a drive towards an external system.
I/O drive operations can be calculated as the number of I/O operations performed per second (IOPS) or as a transfer speed (the size of the data transferred for a second).
IOPS (Input/output Operations per Second) – the number of input-output operations per second, performed from/towards the SSD drives of the server.ървъра.
If compared to the common hard disc drives, solid state drives support more operations per second and a higher transfer rate.
SSD are distinguished from standard HDD by their exceptional features. The most crucial of them are allowing instant access to data and the impressive number of simultaneous operations per second as well as excellent performance.
