HGST 200GB SAS SSD 0B26577 Leaflet

1  One gigabyte (GB) is equal to one billion bytes, one terabyte (TB) equals 1,000 GB (one trillion bytes), and one petabyte (PB) equals 1,000TB (one  
  quadrillion bytes) when referring to hard drive or solid state drive capacity. Accessible capacity will vary from the stated capacity due to formatting  
  and partitioning of the 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.
