PRELIMINARY/CONFIDENTIAL
MACH2 2.5-Inch Serial ATA Solid State Drive 61
Electrostatic Discharge (ESD)
The SSD will meet the ESD limits specified in the 61000-4-2 guidelines and the customer’s enhanced
ESD procedure. The specification will determine whether the contact or air discharge method should
be used. Performance degradation is defined as a decreased throughput rate. No data errors are
allowed. Table 30 lists the ESD requirements.

A
The apparatus will continue to operate as intended, i.e., normal unit
operation with no degradation of performance.
B
The apparatus will continue to operate as intended after completion of
the test. However, during the test, some degradation of performance is
allowed provided there is no data loss or operator intervention to restore
apparatus function.
C
Temporary loss of function is allowed. Operator intervention is
acceptable to restore apparatus function.
Note: Hardware failures are not acceptable for any level of the above
performance criteria.
