Power Consumption
The amount of power consumed by Zeus SSDs is determined by the storage (memory)
capacity of the drive, and the flash controller/memory configuration of the drive. Table 3
lists (by capacity) the power consumption of Zeus SSDs during typical operations at 5
Vdc.

HARACTERISTICS
1.7.1
ATA (IDE) Bus Modes
Zeus SSDs support the following ATA operating modes:
•
PIO Modes 0 through 4
•
Ultra DMA Modes 0 through 4
1.7.2
Mount Time
The amount of time required to initialize and mount a Zeus SSD varies, depending on the
operating system (Windows
®
, Linux
®
, etc.) in which the SSD is running and the storage
capacity of the drive.
1.7.3
Seek Time
Unlike a magnetic rotating disk, the Zeus SSD has no moving head or platter. There is
no seek time or rotational latency issues to contend with. Zeus SSDs dramatically
improve transaction throughput, particularly for applications that are configured to take
advantage of the characteristics of the drive.
