Whether you are a professional photographer, videographer, or simply someone with a large collection of files, this hard disk drive is designed to meet your storage needs.
Benefits of 4TB Capacity
Having a 4TB capacity means that you can store a vast amount of data without worrying about running out of space. This is particularly beneficial for businesses that deal with large amounts of data on a daily basis. With 4TB at your disposal, you can store countless documents, images, videos, and more without the need for additional external drives.
Ample Space for Multimedia Files
If you are a content creator or work in the media industry, the 4TB capacity of this hard disk drive is essential. High-resolution videos and images can occupy significant amounts of space, and having 4TB ensures that you can store all your work without compromising on quality or deleting older files.
Convenient Backup Solution
Backing up your important files and data is crucial to ensure their safety. With the 4TB capacity, you can easily create regular backups of your entire system or specific folders. This provides peace of mind knowing that your valuable data is securely stored in case of any unforeseen events such as hardware failures or accidental deletions.
Scalability and Future-Proofing
In today's digital age, data sizes are constantly increasing. What may seem like a lot of storage today may quickly become insufficient in the near future. By opting for a hard disk drive with a 4TB capacity, you are investing in a scalable solution that can accommodate your growing storage needs for years to come.
Speed: 7.2K RPM
The Seagate ST4000NM0295 Hard Disk Drive boasts a speed of 7.2K RPM (Revolutions Per Minute), which contributes to its excellent performance and responsiveness. This feature is particularly important for users who require fast data access and transfer speeds.
Benefits of 7.2K RPM Speed
The high rotational speed of 7.2K RPM offers several advantages that enhance the overall user experience and productivity.
Improved Data Access Time
A higher RPM translates to faster data access time, reducing the waiting time when retrieving or transferring files. Whether you are copying large files, running resource-intensive applications, or accessing data simultaneously from multiple users, the 7.2K RPM speed ensures smooth and efficient operations.
Enhanced Performance for Gaming and Multimedia
Gamers and multimedia enthusiasts often require quick loading times to enjoy their favorite games or media content without interruptions. The 7.2K RPM speed of this hard disk drive significantly reduces loading times, allowing for seamless gameplay and uninterrupted streaming of high-definition videos.
Reduced Latency
Latency refers to the delay between a request for data and the actual retrieval or transfer of that data. With a higher rotational speed, the 7.2K RPM drive minimizes latency, resulting in faster response times and smoother overall system performance.
Buffer: 128MB
The Seagate ST4000NM0295 Hard Disk Drive is equipped with a generous buffer size of 128MB, which plays a crucial role in optimizing performance and ensuring smooth operations.
Benefits of 128MB Buffer Size
The buffer acts as a temporary storage area that holds recently accessed data, reducing the need for frequent access to the physical disk. The larger the buffer size, the more data can be stored temporarily, resulting in improved performance and responsiveness.
Efficient Data Caching
With a 128MB buffer, this hard disk drive can efficiently cache frequently accessed data. This allows for quicker retrieval of data, especially for applications or files that are accessed repeatedly. The buffer acts as a bridge between the disk and the system, ensuring smooth data flow and minimizing delays.
Seamless Multi-Tasking
If you often find yourself working on multiple tasks simultaneously, the 128MB buffer size proves invaluable. It enables seamless multi-tasking by storing frequently accessed data from different applications, allowing for faster switching between tasks without experiencing significant slowdowns.
Optimized Performance for Large Files
Working with large files, such as high-resolution images or videos, can put a strain on system resources. However, with a 128MB buffer size, this hard disk drive can efficiently handle large file transfers and editing tasks without compromising performance. Whether you are editing videos or manipulating complex graphics, the buffer ensures smooth operations even with resource-intensive applications.
Interface: SAS
The Seagate ST4000NM0295 Hard Disk Drive utilizes a SAS (Serial Attached SCSI) interface, offering advanced connectivity and performance capabilities for users who require reliable and high-speed data transfer.
Benefits of SAS Interface
The SAS interface provides numerous benefits compared to traditional interfaces, making it an ideal choice for users with demanding storage requirements.
Higher Data Transfer Rates
SAS offers significantly higher data transfer rates compared to other interfaces, such as SATA (Serial ATA). This means faster file transfers, improved system responsiveness, and reduced waiting times. Whether you are transferring large files or running data-intensive applications, the SAS interface ensures a seamless experience.
Enhanced Scalability
The SAS interface supports daisy-chaining of multiple devices, allowing for easy expansion and scalability. This is particularly beneficial for businesses or individuals who anticipate future growth and need the flexibility to add more storage devices without major infrastructure changes.
Reliability and Redundancy
SAS is known for its high reliability and fault-tolerant features. It supports redundant data paths, ensuring that if one path fails, the data can still be accessed through an alternate path. This redundancy minimizes the risk of data loss or system downtime, making the SAS interface a preferred choice for critical applications and industries where data integrity is paramount.
Data Transfer Rate: 12GBPS
The Seagate ST4000NM0295 Hard Disk Drive boasts an impressive data transfer rate of 12Gbps (Gigabits per second), providing lightning-fast performance for users who require quick access to their data.
Benefits of 12Gbps Data Transfer Rate
The high data transfer rate of 12Gbps offers several advantages that are crucial for users who deal with large volumes of data and require fast access and transfer speeds.
Rapid Data Backup and Recovery
Backing up important files or recovering data from backups can be time-consuming, especially when dealing with large amounts of data. However, with a 12Gbps data transfer rate, the process becomes significantly faster. You can quickly create backups or restore data, ensuring minimal downtime and improved productivity.
Seamless Video Editing and Rendering
Video editing and rendering are resource-intensive tasks that can benefit greatly from a high data transfer rate. The 12Gbps rate allows for smooth playback, seamless editing, and faster rendering of high-resolution videos. This enables video professionals to work efficiently without experiencing frustrating delays or dropped frames.
Improved System Performance
A faster data transfer rate leads to improved system performance overall. Whether you are running resource-intensive applications, virtual machines, or performing complex calculations, the 12Gbps rate ensures that your system can handle the workload without slowing down or experiencing bottlenecks.
