Reliability The Spressa USB has a mean time between failure (MTBF) rating of 100,000 power on hours (POH) at 25% duty. 25% duty means the Spressa USB is in actual use a quarter of the time the unit is turned on. MTBF is an average failure rate based on the total power on hours divided by the number of drive failures. A failure is any malfunction of the drive that prevents you from using it. This includes failure to power up, load or unload a CD, and read or write data. Faults are not considered failures when they relate to incompatible software or discs, or from mishandling and/or abuse. Reliability ratings are derived from a large statistical sample, and are not indicative of the performance of a single unit. 6 CRX100E/X - Spressa USB User's Guide Controls and Indicators Chapter 2 This chapter shows the connectors, controls, and indicator lights of the Spressa USB.
