2.6Seek time

Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured 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.

Typical seek times (msec)

*Measured in performance mode. **Measured in quiet mode.

Note. These drives are designed to consistently meet the seek times represented in this manual. Physical 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.

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.
