Overview Product Description 1 PRODUCT DESCRIPTION 1.1 OVERVIEW SimpleTech’s Zeus Ultra DMA Solid State Drives (SSDs) incorporate advanced SingleLevel Cell (SLC) NAND flash memory technology to deliver state-of-the-art, non-volatile mass storage devices. Additional software device drivers are not required. Zeus SSDs are available in both 2.5-inch and 3.5-inch form factors, with standard 44 and 40 pin IDE/ ATA interfaces, respectively.
Product Description Overview Standard Zeus SSDs are available with unformatted memory capacities ranging from 4 to 128 GB. Designed to operate in harsh environments, Zeus SSDs excel in ruggedness, reliability, compatibility and portability, and are ideal for applications that require high reliability and high tolerance to shock, vibration, humidity, altitude and temperature. And since there are no moving parts, Zeus SSDs are completely maintenance-free.

Product Description 1.4.2 Environmental Characteristics Drive Assembly Weight The weight of a Zeus SSD varies, depending on the specific set of design characteristics of the drive. A standard 32 GB, 2.5-inch Zeus SSD weighs approximately 0.322 lb (0.120Kg). A 72 GB SSD weighs 0.670 lb (0.250Kg). The following characteristics must be taken into consideration in order to determine the exact weight of a drive.
Electrical Characteristics 1.5.2 Product Description Shock and Vibration In setting the initial baseline for shock and vibration test levels, the Zeus SSD was exposed to increasingly harsh levels of stress until the drive’s failure levels were determined. The tests were then repeated using the stress levels thereby established, to verify that the SSD would meet these specifications consistently.
Product Description 1.6.2 Operation and Performance Characteristics Power Consumption The amount of power consumed by Zeus SSDs is determined by the storage (memory) capacity of the drive, and the flash controller/memory configuration of the drive. Table 3 lists (by capacity) the power consumption of Zeus SSDs during typical operations at 5 Vdc. Table 3. Zeus SSD Typical Power Consumption (watts/mA) 8 GBa 16 GBa 24 GBa 32 Ga 72 GBb 2.50 watts/ 431 mA 2.15 watts/ 431 mA 2.15 watts/ 431 mA 2.
Operation and Performance Characteristics 1.7.4 Product Description Data Transfer Rate The data transfer rate of Zeus SSDs depends on the flash controller/flash memory configuration of the drive. The drive’s scalable architecture is capable of accommodating sustained and burst data transfer rates as follows: Sustained Read/Write Rates: 20, 30, 40 and 60 MB/sec Burst Read/Write Rate: 66 MB/sec 1.7.
Product Description Operation and Performance Characteristics 1.7.6.2 Error Detection and Correction The SSD’s error detection code and error correcting code (EDC/ECC) helps maintain data integrity by allowing single or multiple bit corrections to the data stored in the drive’s 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.
Zeus SSD Functional Blocks Functional Description 2 FUNCTIONAL DESCRIPTION 2.1 ZEUS SSD FUNCTIONAL BLOCKS SimpleTech™ Zeus series solid state drives comprise the following primary functional component blocks: • ATA (IDE) Bus Interface • SSD Control • Flash Memory 2.1.1 ATA (IDE) Bus Interface Block This section provides information on the ATA (IDE) Bus interface connectors used with 2.5-inch and 3.5-inch Zeus SSD.
Functional Description Zeus SSD Functional Blocks 2.1.1.2 3.5-inch SSD ATA Interface and Power Connectors The 3.5-inch Zeus-series SSDs are equipped with a 40-pin, DC power/ATA bus combination connector (Figure 4), located at the rear of the drive. IDE bus traffic is supplied through a non-shielded 40-conductor I/O cable. DC power is supplied through a separate 4-conductor power cable. ATA standards require 80-conductor cables to be used for Ultra DMA modes 3 through 5.

When the pin is grounded, the device is configured as a Master.
Zeus SSD Functional Blocks 2.1.2 Functional Description SSD Control Block The Zeus SSD’s control block comprises three integrated components: • SimpleTech Zeus SSD controller • RISC Microcontroller • NAND SLC flash memory SimpleTech’s Zeus FPGA (Field Programmable Gate Array) controller is the heart of the Zeus SSD. The Zeus controller provides the drive’s ATA interface to the host, and the IDE interface to the drive’s local flash memory.
Functional Description 2.1.3 Zeus SSD Functional Blocks Flash Memory The Zeus SSD’s local storage subsystem uses Single-Level Cell (SLC) NAND, nonvolatile flash memory. Having only two states and one bit of data stored, SLC NAND flash control logic on the SSD is able to conserve energy when managing the electrical charge during operations. 2.1.3.
Principles of Operation 2.2 Functional Description PRINCIPLES OF OPERATION The Zeus SSD comprises three primary functional blocks—the ATA (IDE) interface connector, Zeus SSD controller and NAND flash memory. A description of each drive component is provided in “Zeus SSD Functional Blocks” on page 13. All read/write data transfer requests are initiated by the host via the ATA (IDE) bus interface. Once received, the Zeus controller, under the control of the SSD’s microcontroller, processes the request.
Functional Description 2.3 Operating Modes OPERATING MODES The Zeus SSD is configured as a high-performance I/O device, supporting the following operating modes: • Primary drive address at system ATA I/O address 1F0h - 1F7h and 3F6h - 3F7h. The host must provide chip-enable #CS0 and #CS1. The SSD decodes addresses DA0 - DA2. • Secondary drive address at system ATA I/O address 170h - 177h and 376h - 377h. The host must provide chip-enable #CS0 and #CS1. The SSD decodes addresses DA0 - DA2. 2.3.
ATA Commands Functional Description Table 6. 2.
Functional Description 2.4.2 ATA Commands Standard ATA Commands Table 7 lists each command along with its respective command code and registers accessed by the command. For detailed descriptions of the ATA commands, refer to the ATA-5 specification. Table 7.
ATA Commands 2.4.3 Functional Description Optional ATA Command Support 2.4.3.1 SMART (Self-Monitoring, Analysis and Reporting Technology) Zeus SSDs are designed to operate in mission-critical systems where remote monitoring of the drives’s internal status is required, but removal of the drive for status checking is unacceptable. To provide remote monitoring support, Zeus SSDs can be programmed with the optional SMART feature.
Functional Description ATA Commands Table 8. a.
ATA Commands 2.4.4 Functional Description Vendor-Specific ATA Commands As with standard ATA command, the software requirements and syntax of the vendorspecific ATA commands the host issues to the Zeus SSD are issued to the ATA by loading the required registers in the command block with the supplied parameters, and then writing the command code to the register. For additional information on proprietary SimpleTech ATA commands, contact your SimpleTech representative.
Functional Description ATA Commands 2.4.4.2 Sanitization Standards Zeus SSDs comply with the sanitization requirements described in Table 9. Table 9. Sanitize Standards Compliance Specification Document Description/Comment USA DoD 5220.22-M National Industrial Security Program Operation Manual (NISOM) January 1995 Specifies the sanitization process for various media types in order to be considered declassified.
