SAS, SCSI and other server disks also have SMART, but its presentation is very different from SATA / PATA.

I note that the following applies to drives with SATA and PATA interfaces. This complex is quite extensive, but we will talk about those aspects of it that allow you to look at the SMART attributes displayed in any hard drive testing program and understand what is happening with the disk. Information about the state of the disk is available through a set of technologies called the common name SMART (Self-Monitoring, Analisys and Reporting Technology, that is, the technology of self-monitoring, analysis and reporting). No other component of the system unit provides the owner with statistics of their work! Coupled with the fact that HDD is one of the most unreliable components of a computer, such statistics can be very useful and help its owner avoid the hassle and waste of money and time.

This information contains the history of changes in the set of parameters monitored by the hard drive during operation. It is unique in that it stores service information in itself, by studying which you can evaluate the "health" of the disc. Modern hard drive - a unique component of the computer.
