CAPACITY: One MB is equal to one million bytes, 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 will vary from the stated capacity due to formatting and partitioning of the hard drive, the computer’s operating system, and other factors.
MTBF: MTBF target is based on a sample population and is estimated by statistical measurements and acceleration algorithms under median operating conditions. MTBF ratings are not intended to predict an individual drive’s reliability. MTBF does not constitute a warranty. DATA BUFFER: Portion of buffer capacity used for drive firmware.
TRANSFER RATE: MB is equal to Million Bytes; Sustained rate is shown from Outer to Inner DiameterMODEL NUMBER POSSIBLE VALUES y=0 (Instant Secure Erase), y=1 (TCG SED), y=4 (Secure Erase, overwrite), y=5 (FIPS 140-2 certified TCG-SED)
