22TB WD WD221KFGX Red Pro NAS 7200RPM 512MB
22TB, 3.5", SATA 6Gb/s, 7200RPM, CMR Western Digital Red Pro, 3.5 inch, 22000 GB, 7200 RPM Western Digital Red Pro. HDD size: 3.5 inch, HDD capacity: 22000 GB, HDD speed: 7200 RPM For the needs of large companies The WD Red™ Pro hard drives are specially designed for medium to large business customers and are available for NAS systems with up to 24 drive bays. Targeted at high-intensity workloads in 24x7 environments, the WD Red™ Pro family is ideal for archiving and sharing content, as well as building RAID arrays in advanced operating systems such as ZFS and other file systems. These hard drives increase efficiency by allowing your employees to quickly share files and reliably back up folders in your NAS solution. Exclusive NASware™ 3.0 technology The exclusive and modern NASware™ 3.0 firmware technology ensures seamless integration, robust data security and optimal performance for heavily used NAS systems. Built into every WD Red™ Pro hard drive, NASware 3.0 improves your system's storage performance with the latest technologies and improved compatibility, integration, upgradeability and reliability. Engineered for optimal NAS compatibility WD Red™ Pro hard drives with NASware™ technology simplify hard drive choice. Our unique algorithm is optimized for NAS systems and ensures the right balance of performance and reliability in NAS and RAID environments. In short: WD Red™ Pro is the hard drive with the highest compatibility for NAS enclosures. This is also proven by numbers. WD Red™ Pro hard drives are the result of extensive compatibility testing and extensive integration of technologies from our NAS partners. Protection against impact for drive bays in large NAS systems WD Red™ Pro hard drives are equipped with a multi-axis shock sensor to detect even the slightest shock and a dynamic head height adjustment that automatically compensates for shocks with every read/write operation, protecting your data. The combination of these technologies provides even more hard drive protection in large 24-bay NAS environments and increases hard drive reliability. 3D Active Balance Plus Our advanced dual plane mass balancing technology greatly improves the overall performance and reliability of the drive. Disks that are not properly mass balanced can cause excessive vibration and noise in a multi-drive system, reducing disk life and degrading performance over time. Protection through troubleshooting Because WD Red™ Pro hard drives are specifically designed for RAID and NAS environments, they have special error recovery mechanisms that are part of NASware™ 3.0 technology. In this way, hard disk failures in RAID systems can be significantly reduced. Comprehensive hard drive tests A NAS environment with up to 24 drive bays puts a considerable strain on a hard disk in terms of increased vibration and heat generation. That's why every WD Red™ Pro hard drive undergoes extensive break-in tests with changing temperatures, which ensure even higher reliability in operation. Longer Warranty Coverage WD Red™ Pro hard drives are backed by a 5-year warranty for added peace of mind. Desktop drives versus WD Red™ Pro Choose the right NAS-optimized hard drive with a variety of features so you can protect your data and keep performance at its peak. Consider the following when choosing a hard drive for your NAS system: - Compatibility: Unlike desktop drives, these drives are specifically tested for compatibility with NAS systems to ensure optimal performance. - Reliability: The continuous operation of a NAS or RAID is extremely demanding. Desktop hard drives are usually not designed and tested for these conditions - unlike the WD Red™ Pro. - Error recovery mechanisms: WD Red™ Pro NAS hard drives are specially designed with RAID error recovery protocols that help reduce failures in the NAS system. - Noise and Vibration Protection: Because desktop drives are designed for standalone operation, they typically offer little or no protection from the noise and vibration found in multiple-drive systems. WD Red™ Pro hard drives are optimized for use in multi-bay NAS environments. characteristics HDD size: 3.5 inch HDD Capacity: 22000GB HDD speed: 7200RPM Interface: Serial ATA III Type: HDD Component for: NAS Hot Swap: No Storage drive buffer size: 512 MB Transmission rate HDD interface: 6 Gbit/s Error Recovery Control (ERC): Yes Extended Format (AF): Yes Shock Sensor: Yes 24/7 Operation: Yes Start/stop cycles: 600000 Native Command Queuing (NCQ): Yes Payload limit: 300 TB/year Noise level in sleep mode: 20 dB Mean time between failures (MTBF): 1000000 h Performance Power consumption (standby): 1.2 W Power consumption (idle): 3.4 W operating conditions Operating temperature: 0 - 65 °C Storage temperature range: -40 - 70 °C Shockproof (operating): 40 G Shockproof (non-operating): 200 G weight and dimensions Width: 101.6mm Height: 26.1mm Depth: 147mm Weight: 670g packaging data amount: 1

When using hard disks with SMR in a RAID array, make sure that the RAID controller (or NAS system) is compatible with SMR hard disks so that the partially blocked recording behavior with SMR is not mistakenly interpreted as a "hardware defect".
