Product Specification and User Manual
41-PS-0104-00 Rev. 2.3
3.3.7.
Power Consumption
The SSD requires input voltage of +5VDC, with a tolerance of 5% (4.75V-5.25V) and a
maximum ripple of 250 mV peak-to-peak. Table 3 describes the power consumption based on
Capacity. The power consumptions depend on the disk Capacity and the flash components being
used.

Endurance
The SSD product life span and the performance are enhanced by the following features:
Dynamic Wear-Leveling Algorithm
: This algorithm guarantees the use of all flash blocks
at the same level of stress (write/erase cycle). The dynamic wear-leveling algorithm
eliminates situations where repeated writes to the same logical location cause flash block
wear-out. The dynamic wear-leveling algorithm functions by mapping logical blocks to
physical blocks (transparent to the customer application).
Garbage Collection Process
: The garbage collection process eliminates the need to perform
erasure prior to every write, thus eliminating excessive disk deterioration.
EDC/ECC (Error Detection Code/Error Correction)
: The EDC/ECC extends disk
endurance by detecting and then fixing flash bits.
Bad-Block Mapping Algorithm
: This algorithm replaces bad blocks with new ones from
available spares.
