Description
More Feature
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 24×7 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.
Exceptional Compatibility
The Western Digital HGST 18TB 7.2K RPM SATA 6GBPS 3.5inch Enterprise Hard Drive (WUH721818ALE6L1) is designed for enterprise use and should have a high level of reliability. It has a MTBF (Mean Time Between Failures) rating of 2.5 million hours, which is significantly higher than consumer-grade hard drives. Additionally, it has features such as Advanced Format technology, which increases the hard drive’s ability to handle errors and recover from them. However, it is worth noting that the reliability of any hard drive can be affected by factors such as usage conditions and proper handling.
Backup & Restore Facilities
The Western Digital WUH721818ALE6L1 (previously HGST) is an 18 terabyte (TB) hard drive with a rotation speed of 7,200 revolutions per minute (RPM). It uses the SATA interface and has a data transfer rate of 6 gigabits per second (GB/s). It is a 3.5-inch form factor enterprise hard drive, which is typically used in data centers and other enterprise environments for data storage and backup. The drive is designed to handle heavy workloads and 24×7 operations which makes it suitable for large-scale data storage, archiving and backup applications.
