2.12Reliability

2.12.1Annualized Failure Rate (AFR)

The product shall achieve an Annualized Failure Rate (AFR) of 0.62% when operated in an environment of ambient air temperatures of 25°C. Operation at temperatures outside the specifications in Section 2.9 may increase the product AFR. AFR is a population statistics that is not relevant to individual units.

AFR specifications are based on the following assumptions for DVR/PVR environments:

•8760 power-on-hours per year.

•10,000 average motor start/stop cycles per year.

•Operations at nominal voltages.

•Temperatures outside the specifications in Section 2.9 may reduce the product reliability.

•Normal I/O duty cycle for DVR/PVR devices. Operation at excessive I/O duty cycle may degrade product reliability.

The consumer electronics environment of power-on-hours, temperature, and I/O duty cycle affect the product AFR.

2.13Agency certification

2.13.1Safety certification

The drives are recognized in accordance with UL 1950 and CSA C22.2 (950) and meet all applicable sections of IEC950 and EN 60950.

2.13.2Electromagnetic compatibility

Hard drives that display the CE mark comply with the European Union (EU) requirements specified in the Elec- tromagnetic Compatibility Directive (89/336/EEC). Testing is performed to the levels specified by the product standards for Information Technology Equipment (ITE). Emission levels are defined by EN 55022, Class B and the immunity levels are defined by EN 55024.

Drives are tested in representative end-user systems. Although CE-marked Seagate drives comply with the directives when used in the test systems, we cannot guarantee that all systems will comply with the directives. The drive is designed for operation inside a properly designed enclosure, with properly shielded I/O cable (if necessary) and terminators on all unused I/O ports. Computer manufacturers and system integrators should confirm EMC compliance and provide CE marking for their products.

ST3320310CS, ST3500321CS, ST3320410CS, ST3160310CS, ST3500422CS specifications

Seagate has long been recognized as a leader in data storage solutions, and their range of hard drives continues to reflect innovation and reliability. Among the notable SATA drives are the Seagate ST3500422CS, ST3160310CS, ST3320410CS, ST3500321CS, and ST3320310CS models, all designed for various consumer and enterprise applications.

The ST3500422CS operates at a capacity of 500GB, combining high performance with energy efficiency. With a spindle speed of 7200 RPM and a 32MB cache, it ensures rapid data access and transfer rates, making it suitable for multimedia storage and gaming applications. This drive incorporates Seagate’s Instant Secure Erase technology, which allows users to securely wipe their data quickly, ensuring privacy and data protection.

Next, the ST3160310CS model offers a storage capacity of 160GB, ideal for smaller applications requiring faster access times. Also spinning at 7200 RPM, it features a similar 8MB cache, ensuring good performance for everyday computing needs. Its compact design makes it suitable for both desktop systems and where space is at a premium.

The ST3320410CS is designed for larger capacity requirements, providing up to 320GB of storage space. This drive features enhanced data integrity with a 16MB cache and a consistent performance level that makes it suitable for both personal computing and lightweight server applications. Its Balancing Act technology optimizes the drive's performance across multiple workloads, extending its lifespan.

The ST3500321CS provides users with 500GB of storage, similar to the ST3500422CS but with a focus on data reliability. Featuring advanced error correction technologies, it diminishes the chance of data loss, making it a great choice for critical applications requiring consistent reliability.

Finally, the ST3320310CS model holds 320GB of storage capacity and shares many characteristics with its counterparts, such as the 7200 RPM speed and strong error correction mechanisms. The drive also utilizes Seagate's Thermal Fly-Height Control technology, which further enhances reliability by adjusting the read/write heads according to the drive's operational temperature.

Overall, these drives exemplify Seagate's commitment to performance, efficiency, and data protection across their various storage solutions. With a range of capacities and features, they cater to diverse user needs while ensuring reliability and speed in data access.
