Data Retention
As a NAND Flash device ages with use, its capability to retain a programmed value is
affected by the number of PROGRAM and ERASE operations to its cells, causing deterio-
ration. When new, the device has a powered-off data retention capability of several
years, but with use, data retention is reduced.
Temperature also affects how long the device retains its programmed value when power
is removed. High temperature reduces retention capability when power is off, but is not
an issue when power is applied. The SSD drive contains firmware and hardware fea-
tures that can monitor and refresh memory cells when power is applied.

Endurance
Endurance rating is the expected amount of host data that can be written by product
when subjected to a specified workload at a specified operating and storage tempera-
ture over the specified product life. For the specific workload to achieve this level of en-
durance, refer to JEDEC specification JESD218. TBW is defined as 1 x 10
12
bytes.

Density Endurance Rating Unit Notes
400GB 7000 TBW 1, 2
800GB 14,000
Notes:
1. Limited warranty with media usage provides coverage either for the warranty period or
until the SSD percentage used endurance indicator reaches 100, whichever comes first.
2. TBW per the JEDEC JESDS218 specification assuming typical workloads are 50% sequen-
tial and 50% random and consist of the following: 5% are 4KB; 5% are 8KB; 10% are
16KB; 10% are 32KB; 35% are 64KB; and 35% are 128KB.

Electrical Characteristics
Device DC power (+3.3V and +5V) is through the standard SAS interface. Typical power
measurements listed below are based on an average of drives tested, under nominal
conditions, using the listed input voltage at 60°C internal temperature. Measurements
are made at 12Gb interface speeds.
Startup power: Measured from power-on to when the drive reaches operating condi-
tion and can process media access commands.
Peak operating mode power: Measured by testing the drive in various read and write
access patterns that simulate worst case power consumption.
Idle mode power: Measured when the drive is powered up and ready for media access
commands, but before the host has sent the commands.
Note: Stresses greater than those listed in the following tables may cause permanent
damage to the device. These are stress ratings only and device operation above ratings
or conditions listed in the operation sections of this specification is not implied. Expo-
sure to absolute maximum rating conditions for extended periods may affect reliability.

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.
