Capacity GB - One GB is equal to one billion bytes and one TB equals 1,000GB (one trillion bytes) when referring to hard drive capacity. Accessible capacity may be less.
Availability - Based on typical AV multi-stream recording environments accumulating up to 2000 hours of HD content per month or equivalent workload.
Targeted MTBF - This MTBF target is based on a sample population in typical CE/ surveillance product environment and is estimated by statistical measurements and acceleration algorithms under normal operating conditions.
MTBF ratings do not predict reliability of an individual drive.
Data Buffer MB - Portion of buffer capacity used for drive firmware. 1TB has 16 MB buffer.
Device Temperature - Temperature tested at top cover surface
