Below are answers to frequently asked questions about the Western Digital WD400BEAE hard drive, based on available technical information and user discussions.
Q: What is the Western Digital WD400BEAE?
A: The Western Digital WD400BEAE is a 4TB internal hard disk drive designed for use in desktop computers and external storage enclosures. It operates at a spindle speed of 5400 RPM and features a SATA 6Gb/s interface.
Q: What are the key specifications of the WD400BEAE?
A: Key specifications include a storage capacity of 4TB, a 5400 RPM rotational speed, a 64MB cache buffer, and a SATA 6Gb/s transfer rate. The drive uses 3.5-inch form factor and consumes lower power compared to 7200 RPM drives.
Q: Is the WD400BEAE suitable for video recording or surveillance systems?
A: This drive is primarily designed for general-purpose storage and is not specifically optimized for 24/7 operation in surveillance systems. For continuous recording environments, Western Digital offers specialized Purple series drives with enhanced write endurance and reliability features.
Q: What is the typical power consumption of this drive?
A: During read/write operations, the WD400BEAE typically consumes around 5.3 watts of power. In idle mode, power consumption drops to approximately 4.2 watts. The drive supports advanced power management features including low-power spin-down states when not in use.
Q: Does the WD400BEAE support Advanced Format (AF) technology?
A: Yes, the WD400BEAE uses Advanced Format technology with 4K physical sector sizes. This improves error correction efficiency and storage density. The drive is compatible with operating systems that support AF, and most modern systems handle this transparently.
Q: What is the operating temperature range for this drive?
A: The recommended operating temperature range is 0°C to 60°C (32°F to 140°F). For non-operating storage, the drive can withstand temperatures from -40°C to 70°C (-40°F to 158°F). Proper ventilation in the computer case is important to maintain safe operating temperatures.
Q: How does the WD400BEAE compare to a 7200 RPM drive?
A: Compared to 7200 RPM drives, the WD400BEAE offers lower power consumption and less heat generation, but with slightly slower sequential data transfer speeds. This drive is better suited for bulk storage of files, backups, and media libraries where quiet operation and energy efficiency are priorities over maximum performance.
Q: What is the warranty period for the WD400BEAE?
A: The Western Digital WD400BEAE typically comes with a limited 2-year warranty from the date of purchase. Warranty terms may vary by region and retailer. Users are advised to check the specific warranty details provided at the time of purchase or on Western Digital’s official support portal.
Q: Can this drive be used in a RAID configuration?
A: Yes, the WD400BEAE can be used in RAID 0, 1, 5, or other RAID levels. However, for RAID arrays with multiple drives, Western Digital recommends using drives from their Red or Gold series, which include features like TLER (Time-Limited Error Recovery) to maintain compatibility with RAID controllers.
Q: What does the model number WD400BEAE indicate?
A: In the model number, “WD” stands for Western Digital, “400” indicates the approximate capacity of 4TB, and “BEAE” is a product code designating the specific hardware revision and feature set. The “E” may refer to the 5400 RPM speed class, while the “A” denotes the generation or interface type.
