Below are answers to frequently asked questions about the Seagate ST3250412CS hard drive, based on available technical information and user discussions.
Q: What is the Seagate ST3250412CS?
A: The Seagate ST3250412CS is a 250GB hard disk drive designed for consumer electronics applications including DVRs and PVRs. It operates at a rotational speed of 7200 RPM and features a SATA 3.0 Gb/s interface with a 16 MB cache buffer.
Q: What are the key specifications of the ST3250412CS?
A: Key specifications include a 250 GB formatted capacity, a 7200 RPM spindle speed, a SATA 3.0 Gb/s interface, a 16 MB cache, an average latency of 4.16 ms, and a seek time of typically 8.5 ms for reads and 9.5 ms for writes. The drive uses perpendicular recording technology.
Q: Is the ST3250412CS suitable for use in a desktop computer?
A: While the ST3250412CS is primarily designed for consumer electronics devices like DVRs, it can be used in a desktop computer. However, it is optimized for streaming video workloads and may not provide the same performance as desktop-focused drives in random access or multi-user environments.
Q: What is the power consumption of this hard drive?
A: The ST3250412CS typically consumes around 6.5 watts during read/write operations and approximately 5.0 watts during idle. In standby and sleep modes, power consumption drops to about 0.8 watts and 0.2 watts respectively.
Q: What is the noise level of the ST3250412CS?
A: The drive operates with a low acoustic profile. Idle noise is rated at approximately 2.7 bels, and during seek operations, noise increases to around 2.8 bels. These levels make it relatively quiet for a 7200 RPM drive.
Q: Does the ST3250412CS support NCQ (Native Command Queuing)?
A: Yes, the Seagate ST3250412CS supports Native Command Queuing, which allows the drive to reorder incoming commands to optimize data transfer efficiency and reduce latency.
Q: What is the typical lifespan or reliability of this hard drive?
A: The ST3250412CS has a Mean Time Between Failures (MTBF) rating of approximately 700,000 hours. Actual lifespan depends on usage conditions including temperature, vibration, and power cycling frequency. It is designed for 24/7 operation in DVR environments.
Q: Can I use the ST3250412CS in a RAID array?
A: This drive is not specifically optimized for RAID deployments. It lacks features such as TLER (Time-Limited Error Recovery) which is commonly found in enterprise or NAS drives. Using it in a RAID array may lead to drive dropouts under certain error conditions.
Q: What is the form factor and weight of the ST3250412CS?
A: The drive uses a standard 3.5-inch form factor with dimensions of approximately 147.0 mm x 101.85 mm x 26.1 mm. It weighs about 635 grams.
Q: Is the ST3250412CS compatible with older SATA revisions?
A: The drive supports SATA 3.0 Gb/s but is backward compatible with SATA 1.5 Gb/s interfaces. A SATA-to-PATA converter is not available as the drive uses a native SATA interface.
Q: What is the operating temperature range for this hard drive?
A: The recommended operating temperature range is 0°C to 60°C (32°F to 140°F). Non-operating temperature tolerance extends from -40°C to 70°C (-40°F to 158°F). Good airflow around the drive is advised for sustained operation.
Q: Does the ST3250412CS have any special firmware for streaming applications?
A: Yes, this drive features Seagate’s SmoothStream technology, which is a firmware optimization designed to reduce video playback stutter and improve recording reliability in time-sensitive DVR and PVR environments.
