GENERAL DESCRIPTION
PRODUCT DESCRIPTION
The Zeus
Cell (SLC) NAND flash memory technology to deliver a state-of-the-art, non-volatile mass storage
device. The interface is fully SCSI compliant and conforms to the same mechanical and mounting
requirements as a standard rotating disk drive. The SSD is an easy-to-install, drop-in replacement for
standard SCSI-compliant hard disk drives (HDDs). No additional device drivers are required to fully
support the drive as a boot or data storage device.
IOPS
3.5-inch Fibre Channel Solid State Drive (SSD) incorporates advanced Single-Level
FIBRE CHANNEL INTERFACE
The SSD can be installed in any operating system environment that supports FCP-4 devices. The
Fibre Channel Protocol (FCP) is a method for transmitting SCSI commands and data over FC-FS-2
Exchanges and Information Units. It is a high-speed serial architecture that allows for connections
over optical or electrical cable. It also supports fabric-switched and arbitrated-loop network
topologies.
DRIVE CAPACITIES
IOPS
Zeus
gigabytes. The SSDs are ideal for applications that require high reliability and high tolerance to
shock, vibration, humidity, altitude and temperature. Since there are no moving parts, the SSDs are
completely maintenance-free.
3.5-inch SSDs are available with unformatted memory capacities of 18, 36, 73 and 146
PERFORMANCE
The SSDs can operate at sustained data transfer rates of up to 200 megabytes per second. The
drives are capable of performing 50,000 random operations per second. Power consumption is kept
to a minimum; the SSDs can be powered from a single 12-volt source. The solid state design
eliminates electromechanical noise and delay inherent in traditional magnetic rotating media. The
wear-leveling and bad-block mapping algorithms ensure consistency, accuracy, and integrity of user
data. Superior data reliability is achieved through embedded Error Detection Code and Cyclic
Redundancy Checking (EDC/CRC).
DATA SECURITY

Zeus
capacity of the drive. The drive can also be “sanitized”, thereby making data recovery impossible. See
Erase Times and Sanitize on page 10.
Zeus
SSDs offer erase and data sanitization (purge) features. Erase times vary according to the
IOPS
3.5-Inch Fibre Channel Solid State Drive Product Manual Rev. 1.0 23
PERFORMANCE CHARACTERISTICS
ENDURANCE
The useful life of the flash media is limited by the number of write/erase operations that can be
performed on the media. Typically, the write/erase cycles for flash media ranges between 100,000
and 300,000. To extend the life of the SSD, special Wear-Leveling and Bad-Block Mapping
algorithms are integrated into the firmware, increasing the overall endurance rating of the drive to
2,000,000 Write/Erase cycles.
WEAR-LEVELING ALGORITHM
The dynamic wear-leveling algorithm guarantees that erase/write cycles are evenly distributed
across all the flash memory block locations. Wear-leveling eliminates repeated writes to the same
physical flash memory location, thereby preventing blocks from premature wear.
BAD-BLOCK MANAGEMENT
The bad-block management scheme will detect faulty blocks during operation. Bad blocks are
flagged in a defect list. Blocks within the defect list are excluded and are never used for data storage.
DATA RETENTION
Data stored on Zeus
The unit can be stored at temperatures between -40
occurrence of data degradation.
ERROR DETECTION AND CORRECTION
IOPS
SSDs will remain valid for ten (10) years without requiring power support.

The Error Detection Code and Error Correcting Code (EDC/ECC) algorithm helps maintain data
integrity by allowing single or multiple bit corrections to the data stored in the flash array. If the data
in the flash array is corrupted due to aging or during the programming process EDC/ECC will
compensate for the errors to ensure the delivery of accurate data to the host computer. The EDC/
ECC engine on the drive is capable of correcting 8 random or 12 sequential bytes in 1,024 bytes. The
possibility of undetected errors or incorrect correction is eliminated with additional CRC.
RELIABILITY
• DC power is maintained as specified in the product manual.
• Errors caused by host are excluded from rates.
• Errors from the same causes are counted as 1 block.
• Data stream is assumed random.

MOUNT TIME
The amount of time required to initialize and mount a Zeus
system (Windows®, Linux®, etc.) and the storage capacity of the drive.

ACCESS TIME
Unlike a magnetic rotating disk, the Zeus
access time ranges from 20μsec to 120μsec. The actual access time may be affected by the
operating system and the storage capacity of the drive.
IOPS
SSD has no moving read/write head or platter. The
DATA TRANSFER RATES
The data transfer rates of the SSD are outlined in Table 2. Access times are measured under nominal
temperature and voltages from a representative sample of the drive. The access times are measured
from receipt of last byte of the Command Descriptor Block (CDB) to the request for a Status Byte
Transfer to the Initiator, excluding Connect/Disconnect.

ERASE TIMES
The time required to erase a Zeus
Erase utility will erase every physical memory storage location that can be accessed by the host
interface. It will also destroy any saved messages. Once initiated, the SSD will be offline and the host
will be unable to access the drive. Once the erase operation is completed the SSD will be restarted.
If power ceases during this operation, the operation will be restarted when power is restored. See
Table 3.

SANITIZE
For sensitive data that requires more stringent security measures, the SSDs are designed to comply
with industry-standard data protection methods. The SSDs support the sanitize standards as detailed
in DoD 5220.22-M, AFSSI 5020 and NSA 130-2. The Sanitize feature will erase every physical
memory storage location and then will write data patterns to all possible NAND locations that are
accessible to the host system. It will also destroy any saved messages. The time required to sanitize

a Zeus
requires different levels of erase/write cycles. If power is lost during this operation, the operation will
be restarted when power is restored. See Table 4.
