NOTE: See “How to read the Ultrastar model number” at 
left for possible values for last character of model number.
1
  One MB is equal to on 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.
2
  MTBF target is based on a sample population and is estimated by 
statistical measurements and acceleration algorithms under nominal 
operating conditions.  MTBF ratings are not intended to predict an 
individual drive’s reliability. MTBF does not constitute a warranty. 
3
  Portion of buffer capacity used for drive firmware

  1MB/s is equal to 1,000,000 Bytes/s; Sustained Transfer rate is shown  
from Outer to Inner Diameter
5
  Excludes command overhead 
6
  Operating power calculated based on a Random  
RW 4KB workload at Queue Depth of 1
