ST3750330NS, ST31000340NS, ST3250310NS, ST3500320NS specifications

Seagate has long been a leader in the hard drive market, providing various storage solutions for personal and enterprise needs. Among its notable models are the ST3500320NS, ST3320630NS, ST3250310NS, and ST3750330NS, tailored for different applications, particularly in data center environments.

The Seagate ST3500320NS is a 500GB SATA hard drive designed for high-performance computing. One of its key features is a spindle speed of 7200 RPM, which offers quick data access times, significantly reducing latency in read and write operations. This model supports a 3Gb/s SATA interface, ensuring compatibility with a wide range of systems. Another important characteristic of the ST3500320NS is its robust error recovery mechanism, which enhances data integrity, making it suitable for applications where data precision is critical.

The ST3320630NS, on the other hand, is a 320GB variant, also featuring a 7200 RPM spindle speed. This model includes advanced power management features, allowing for reduced energy consumption without sacrificing performance. The drive's design focuses on reliability, designed to handle the demands of continuous operation in RAID configurations or as part of a network-attached storage (NAS) solution. Its dual stage actuator technology ensures more precise positioning of the read/write heads, improving overall performance and durability.

Considered an entry-level model, the ST3250310NS boasts a capacity of 250GB and shares the 7200 RPM speed common to other models. This drive is tailored for cost-effective solutions, providing a balance of price, performance, and reliability for small to medium business environments. Its resilience to shock and vibration makes it suitable for use in mobile workstations and external drives.

Lastly, the ST3750330NS features a significant 750GB capacity while maintaining the same 7200 RPM speed. It offers enhanced caching capabilities with a 32MB buffer, improving data throughput and responsiveness. Designed for high-capacity storage needs, this model is optimized for streaming applications and heavy workloads, reinforcing Seagate's commitment to delivering good performance in demanding scenarios.

All these models embody Seagate's dedication to innovation and reliability, featuring technologies such as Native Command Queuing (NCQ) and S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) to monitor drive health. With years of expertise, Seagate continues to set industry standards for storage solutions, making these models ideal for a variety of professional applications.
