1.2 About Momen tus 5400 FDE. 3 SATA disc driv es

The Momentus® 5400 FDE.3 SATA drives contain DriveTrust technology providing Full Disc Encryption (FDE) using proven Advanced Encryption Standard (AES) data encryption and decryption.
You can elect to use Momentus 5400 FDE.3 SATA drives in one of two different security modes:
1. The ATA Security mode To operate in ATA Security mode, you only need a host system and operating system that supports the
existing ATA Security Command Set. The drive is shipped to operating in this mode, ready to use.
2. The DriveTrust Security mode To enable a robust enterprise-level security and management policy, you may elect to operate in
DriveTrust Security mode. To do so, you will need to use a third-party security application to manage the DriveTrust features. Please contact your system or software provider for more details.
Refer to the table below to determine which mode is best for your particular solution.

FDE drive feature list
• Automatically encrypts (and decrypts) all data on the drive
• Operations are performed with no measurable performance loss
• All user data is encrypted on write operations and decrypted on read operations
FDE benefits
• Drive-level protection of data
• Drives that are stolen, taken out of service, or re-purposed remain fully protected
• Near instantaneous disposal and re-purposing of the drive (ensures that data from previous user is not
accessible by the new drive owner)
• Able to be deployed within a trusted computing environment
The drive encrypts every write operation and decrypts every read operation without user intervention. The encryption and decryption is done on the drive itself, so there is a near-zero performance impact when the drive writes and reads data. The performance-optimized encryption and decryption engine performs at the SATA interface speed.
The purpose of full disc encryption on the drive is to protect the data stored on the drive in the event that the host system is lost or stolen. This data at r est pro tection a ssures th e system own er that if their system is lost or stolen, their data will not be accessible without the correct credentials.
Note. The system reauthenticates the user on powerup and when awakening from sleep mode. It is not
necessary to power down to ensure that the system reauthenticates the user.

Having the encryption/decryption on the drive also provides the highest level of security for data because all data, including the boot sector bytes, operating system, temp and even the swap files are encrypted at the drive level.

1.2.1 Drive state upon shipment

Upon shipment from the Seagate factory, the ATA Security Interface is enabled and functioning. This is referred to as operating in ATA Security mode. The following is the detailed state of the drive upon shipment.
• Full Disc Encryption is active and functioning. All user data is encrypted on write and decrypted on read.
• The user interface to the drive is active and all read and write commands are allowed.
• The ATA user password is null (no value).
• The ATA master password is set to the Security ID (SID).
• ATA Security is set to the unlocked state. No password is required to access the drive. Momentus 5400 FDE.3 SATA drives may be integrated into the computer system in the same way you would
integrate a non-FDE Momentus drive. The encryption key is enabled and operational when the drive leaves the Seagate factory. No user id is
required to access the drive, so the data on the drive is accessible to anyone possessing the drive.

2.7 Seek tim e

Seek measurem ent s a re t ake n wi th nom inal po w er a t 25 °C amb ient temperature. All tim es a re m easu red using drive diagnostics. The specifications in the table below are defined as follows:
• Track-to-track seek time is an average of all possible single-track seeks in both directions.
• Average seek time is a true statistical random average of at least 5,000 measurements of seeks between random tracks, less overhead.
T yp ical seek times (msec) Read
Track-to-track 1.5 Average 11.0 Full-stroke 24.0 Average latency 5.56

seeks, regardless of mode (such as track-to-track and average), are expected to meet the noted values. However, due to the manner in which these drives are formatted, benchmark tests that include command overhead or measure logical seeks may produce results that vary from these specifications.

2.9 Power specifications

The drive receives DC power (+5V) through a native SATA power connector.

2.9.1 Power consumption

Power requirements for the drives are listed in table 3. Typical power measurements are based on an average of drives tested, under nominal conditions, at 25°C ambient temperature.
• Spinup power
Spinup power is measured from the time of power-on to the time that the drive spindle re aches operating speed.
• Seek mode
During seek mod e, the read /write actuator arm move s toward a spe cific positi on on the d isc surface and does not execute a read or write operati on. Servo ele ctronics ar e acti ve. Seek mode power is mea sure d based on three random seek operations every 100 msecs. This mode is not typical.
Read/write power and current Read/write power is measured with the heads on track, based on three 63 sector read or write operations
every 100 msecs.
• Idle mode power
Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in a random track location.
• Standby mode
During Standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/ write electronics are in power-down model

2.9.2 Deferred spinup

Momentus 5400 FDE.3 SATA drives do not support the deferred spinup option. If you require this option, refer to the Momentus 5400.3 SATA Blade Server family of drives.

2.9.3 Conducted noise

Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load 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.
Note. Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write
current.

2.9.4 Voltage tolerance

Voltage tolerance (including noise): 5V ± 5%

2.9.5 Power-manag eme nt modes

The drive provides programmable power management to provide greater energy efficiency. In most systems, you can control power management through the system setup program. The drive features the following power-management modes:
Table 4: Power management modes
Power modes Heads Spindle Buffer
Active (operating) Tracking Rotating Full power Idle, performance Tracking Rotating Self refresh—low power Idle, active Floating Rotating Self refresh—low power Idle, low power Parked Rotating Self refresh—low power Standby Parked Stopped Self refresh—low power Sleep Parked Stopped Self refresh—low power
• Active mode
The drive is in Active mode during the read/write and seek operations.
• Idle mode
The buffer remains enabled, and the drive accepts all commands and returns to Active mode any time disc access is necessary.
• Standby mode
The drive enters Standby mode when the host sends a Standby Immediat e c omma nd. If the ho st has set the standby timer, the drive can also enter Standby mode automatically after the drive has been inactive for a specifiable length of time. The standby tim er delay is established using a Standby or Idle command. In Sta ndby mode, the drive buffer is in Self Refresh Low Power mode, the heads are parked and the spindle is at rest. The drive accepts all commands and returns to Active mode any time disc access is necessary.
• Sleep mode
The drive enter s S leep m ode after rece iv ing a Slee p com man d fro m th e ho st. In Sl eep mod e, th e dr ive buffer is in Self Refresh Low Power mode, the heads are parked and the spindle is at rest. The drive leaves Sleep mode after it receives a Hard Reset or Soft Reset from the host. After receiving a reset, the drive exits Sleep mode and enters Standby mode with all current translation parameters intact.
• Idle and Standby timers
Each time the drive performs an Active function (read, write or seek), the standby timer is reinitialized and begins counting down from its specified delay times to zero. If the standby timer reaches zero before any drive activity is required, the drive makes a transition to Standby mode. In both Idle and Standby mode, the drive accepts all commands and returns to Active mode when disc access is necessary.
