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 and AFR targets are based on a sample population and are estimated by statistical

measurements and acceleration algorithms under median operating conditions. MTBF and AFR

ratings do not predict an individual drive’s reliability and do not constitute a warranty.

How to read the Ultrastar model number

Example: HUH7280xxAL420y = 7200 RPM, xTB, 4Kn SAS 12Gb/s

42 = Interface, 4Kn SAS 12Gb/s

(52 = 512e SAS 12Gb/s,

E6 = 512e SATA 6Gb/s,

N6 = 4Kn SATA 6Gb/s)

0 = Reserved

y

= Data Security Mode

0 = Instant Secure Erase

1 = Bulk Data Encryption (SATA),

TCG SED encryption (SAS)

4 = Secure Erase (overwrite only)

5 = TCG encryption with FIPS (SAS)

NOTE: See “How to read the Ultrastar model number” at the top of the page for possible values for

xx and y.
