2.13.3FCC verification

These drives are intended to be contained solely within a personal computer or similar enclosure (not attached as an external device). As such, each drive is considered to be a subassembly even when it is individually mar- keted to the customer. As a subassembly, no Federal Communications Commission verification or certification of the device is required.

Seagate has tested this device in enclosures as described above to ensure that the total assembly (enclosure, disc drive, motherboard, power supply, etc.) does comply with the limits for a Class B computing device, pursu- ant to Subpart J, Part 15 of the FCC rules. Operation with noncertified assemblies is likely to result in interfer- ence to radio and television reception.

Radio and television interference. This equipment generates and uses radio frequency energy and if not installed and used in strict accordance with the manufacturer’s instructions, may cause interference to radio and television reception.

This equipment is designed to provide reasonable protection against such interference in a residential installa- tion. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television, which can be determined by turning the equipment on and off, you are encouraged to try one or more of the following corrective measures:

•Reorient the receiving antenna.

•Move the device to one side or the other of the radio or TV.

•Move the device farther away from the radio or TV.

•Plug the computer into a different outlet so that the receiver and computer are on different branch outlets.

If necessary, you should consult your dealer or an experienced radio/television technician for additional sug- gestions. You may find helpful the following booklet prepared by the Federal Communications Commission: How to Identify and Resolve Radio-Television Interference Problems. This booklet is available from the Super- intendent of Documents, U.S. Government Printing Office, Washington, DC 20402. Refer to publication num- ber 004-000-00345-4.

DB35.4 specifications

The Seagate DB35.4 series of hard disk drives (HDDs) represents a significant advancement in data storage solutions for digital video recording and other demanding applications. Designed specifically for use in DVRs, NVRs, and related multimedia production environments, the DB35.4 drives are tailored to meet the rigorous requirements of streaming and recording high-definition video content.

One of the standout features of the DB35.4 series is its optimized design for continuous operation. These drives are built to handle workloads that involve constant read and write cycles, making them ideal for multi-channel recording setups. With a Mean Time Between Failures (MTBF) rating of 1.2 million hours, the drives ensure reliability and durability, essential for critical applications in broadcasting and surveillance.

The DB35.4 series supports advanced technologies, including native command queuing (NCQ), which enhances performance by allowing multiple read and write commands to be processed simultaneously. This results in improved data transfer rates and reduced latency, which are vital for applications requiring swift access to stored content. With capacities ranging from 250 GB to 2 TB, the drives provide ample space for storing extensive video libraries.

In terms of performance, the DB35.4 features a rotational speed of 7200 RPM, combined with a SATA interface that enables high-speed data transfers. The drives usually come equipped with 8 MB or higher cache memory, further boosting their efficiency during heavy data loads. This ensures that users experience smooth playback and recording, minimizing the risk of dropped frames or buffering.

Energy efficiency is another key characteristic of the Seagate DB35.4 series. Designed with power management in mind, these drives consume less energy during operation while still delivering optimal performance. This not only reduces operational costs but also contributes to a more environmentally friendly solution for users looking to maximize their storage capabilities without excessive power consumption.

In summary, the Seagate DB35.4 HDDs stand out for their reliability, performance, and efficiency. With their specialized design for multimedia applications, advanced technologies like NCQ, and a focus on energy savings, the DB35.4 series remains a preferred choice for businesses and individuals aiming to optimize their digital storage solutions in a demanding video-centric world.
