No matter how dependable the storage device, sooner or later it wears out. Often, this occurs without warning after tens of thousands of write/erase cycles. Unexpected drive failures can cause a complete disruption of business, resulting in costly downtime and a loss of data and customers. Until now, there has
been no definite way to predict when a storage device will fail. This paper introduces SiliconSystems’ SiSMART (Self-Monitoring Analysis and Reporting Technology), which helps Enterprise System OEMs avoid this problem. By constantly tracking a drive’s usage, SiSMART is able to report to the user the exact amount
of useable life left on the drive. Drive usage information can be requested by the host at any time, and allows for an accurate prediction of the drive’s life. This is
especially important during the qualification process.
