The HGST (Western Digital) Ultrastar DC HC550 18TB hard drive (model number WUH721818ALE6L1) is a high-capacity, enterprise-class hard drive designed for use in data center environments. It has the following features:
- Storage capacity of 18TB
- Rotation speed of 7.2K RPM
- SATA (Serial ATA) interface with a 6 Gbps data transfer rate
- 512MB of cache for improved performance
- Mean time between failures (MTBF) rating of 2.5 million hours, making it suitable for use in high-availability storage systems and servers
- Advanced power management technology to reduce power consumption and lower operating costs
- Designed for use in 24x7 environments and supports both random and sequential data access patterns
- 3.5-inch form factor, which is commonly used in enterprise-grade storage systems
- Advanced Format technology, which increases the physical sector size on the drive from 512 bytes to 4096 bytes, providing more efficient use of disk space and improved error correction capabilities
- Advanced ECC (Error Correction Code) technology, which improves data integrity and reduces the number of disk errors
- SMART (Self-Monitoring, Analysis and Reporting Technology) attributes that provide drive health status information
It is worth noting that, while the drive uses a SATA interface which is slower than SAS and is primarily used in consumer-grade devices such as personal computers, it still has plenty of features that make it suitable for enterprise-grade storage systems.
