Datasheet
Zeus 2.5-Inch ATA Solid State Drive 47
Restriction of Hazardous Materials
STEC Inc., has adopted the RoHS Directive, also known as the Restriction of Hazardous Substances
directive. Zeus SSDs are compliant with the European Parliament and Council Directive, i.e.,
assembled with Pb-free or lead-free components.
Shock and Vibration
In determining the initial baseline for shock and vibration test levels, the SSD is exposed to
increasingly harsh levels of stress until the failure levels of the drive is established. The tests were
then repeated using established stress levels to verify that the SSD would meet these specifications
consistently. The process established the shock and vibration levels that have been used in
subsequent shock and vibration testing.
Failure Criteria
Test failures are defined as:
• Any single hard error (unrecoverable error)
• Damage that renders the product inoperable
• Failure to meet performance specifications
Random Vibration
For random vibration, the device will perform without errors after being tested at 15 min/axis on three
axes (X, Y and Z). During the operational vibration, the drive will be performing continuous reads. The
SSD also adheres to 16.3G RMS per MIL-STD-810F (Random, 20Hz to 2,000Hz; 3 vibration axes).
Vibration levels are listed in Table 18. In addition to the previously mentioned Failure Criteria, during
the operating random vibration, the transfer rate of the drive should not degrade by more than 10%.

Shock
The SSD is shock-tested in accordance with MIL-STD-810F and will operate as specified, without
degradation, when subjected to the following as shown in Table 19.
