Notes:
1. Measured with average reading DC ammeter. Instantaneous +12V current peaks will ex-
ceed these values. Power supply at nominal voltage. Number of drives tested = 6 at 60
°C internal.
2. Sequential READ and WRITE operations are based on 128K block transfer at queue
depth = 32.
Identifier and Supported Settings
Supported power consumption identifier settings are shown in the table below. An IN-
QUIRY SCSI command or MODE SENSE command can be used to query VPD page
0x8D for supported power levels and associated identifiers.
The MODE SENSE and SELECT commands can be used to read, write, and modify the
mode page 0x1A, subpage 1. When the SELECT command is used to write a new identi-
fier value, the value is saved in nonvolatile memory, unchanged until modified.
