Reliability

The CD-RW Recorder has a mean time between the
following (MTBF) rating of as high as 100,000 power on
hours (POH) at 25% duty. 25% duty means the CD-RW
Recorder 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 drive Annual Failure
Rate. 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.
