In actual application environments, since this drive have a 32MByte cache and the cache strategy fine
tuned for NAND flash, the write endurance will exceed this specification

3.11 Power specifications
The drive receives DC power (+5V) through the interface connector.
3.11.1 Power consumption
Power requirement for the drive is listed in the table. Typical power measurements are based on an
average of drive testing, under nominal conditions, using 5.0V input voltage at room temperature.
average of drive testing, under nominal conditions, using 5.0V input voltage at room temperature.
z Warm-up power
Warm-up power is measured from the time of power-on to the time that the drive’s back up power
system has stored enough energy.
system has stored enough energy.
z Read power
The read power is measured with three 63 sectors read operations every 100msecs.
The consecutive read power is measured with consecutive 128Kbytes read operations.
z Write power
The write power is measured with three 63 sectors write operations every 100msecs.
The consecutive write power is measured with consecutive 128Kbytes write operations.
z Idle mode power
The idle power is measured with no read/wrote operation.
z Standby mode power
During Standby mode, the drive accepts commands, and the DRAM cache is in sleep mode and the
MCU is running in slower clock.

3.11.2 Conducted Noise
Input noise ripple is measured at the host system power supply across an equivalent 25-ohm resistive
loading on the +5 volt line.

Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak
square-wave injected noise at up to 10 MHz.
