Notes:
1. Maximum values with all fans running at maximum speed.
2. Power is consumed during the battery back-up time only. The standby power is included in DW700-
CBX.
3. Actual values at a typical I/O condition. (Random Read and Write, 50 IOPSs for HDD, 2500 IOPSs for
SSD, Data Length: 8k bytes) These values may increase for future compatible drives.
