DATA SHEET

ENTERPRISE SOLID-STATE DRIVES

1

One gigabyte (GB) is equal to one billion bytes, one terabyte (TB) is equal to 1,000GB (one

trillion bytes), and one petabyte (PB) is equal to 1,000TB (one quadrillion bytes) when

referring to solid-state drive or hard 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.

How to Read the Ultrastar Model Number

HUSMH8080ASS200 = 800GB, SAS 12Gb/s

H = HGST

U = Ultrastar

S = Standard

MH = Multi level cell, high endurance (25DW/D)

80 = Full capacity (800GB)

80 = Capacity of this model

(80 = 800GB, 40 = 400GB, 20 = 200GB)

A = Generation code

S = Small form factor (vs. L for Large FF)

S2 = Interface, SAS 12Gb/s

0 = Reserved

0 = Crypto sanitize

(1 = TCG encryption, 4 = No encryption,

5 = TCG + FIPS certified encryption)
