* There are unlimited read cycles. Service life is determined using
SiliconSystems’ LifeEst calculation at 100% duty cycle with 25% write cycles.
LifeEst is a comprehensive measurement that considers numerous factors to
determine the projected life span of a SiliconDrive. A white paper that
describes the benefits of LifeEst and how to calculate it can be found at

.
The actual life of a SiliconDrive is dependant on the customer usage model.
SiSMART is a patented technology of SiliconSystems that enables host
systems to monitor actual usage of a SiliconDrive in real time. SiSMART
measures and reports the remaining life of a SiliconDrive. For more
information on SiSMART, refer to the Eliminating Unscheduled Downtime by
Forecasting Useable Life
