Description
Drive Feature
The Western Digital WUH722020BL5204 (previously Ultrastar DC HC560) is a 20 terabyte (TB) hard drive with a rotation speed of 7,200 revolutions per minute (RPM). It uses the SAS (Serial Attached SCSI) interface, which is a high-speed data transfer standard that is commonly used in enterprise and data center environments, and has a data transfer rate of 12 gigabits per second (GB/s). It has a 512MB buffer, and utilizes the 512E (512 emulation) sector format.
It is designed for use in high-performance storage systems and data centers and is suitable for large-scale data storage, archiving, and backup applications. Additionally, it’s built to handle heavy workloads and 24×7 operations which makes it a reliable option for enterprise use. With high capacity, high performance and high reliability, the drive is well suited for use in demanding storage and data center environments.
Backup & Restore Facilities
The Western Digital Ultrastar 20TB 7.2K RPM SAS-12GBPS 512MB Buffer 512e Hard Drive (WUH722020BL5204) is designed for enterprise use and it’s suitable for backup and restore facilities. The high storage capacity of 20TB allows for large amounts of data to be stored on the drive, while the 7200 RPM spindle speed and SAS-12GBPS interface allows for fast data transfer rates. The 512MB buffer and 512e sector format increases the hard drive’s capacity and efficiency.
It also features technologies such as Advanced Format and Advanced Power Management, which can help to increase the reliability and lifespan of the hard drive. Additionally, it’s built-in support for RAID configurations, which can help protect against data loss due to drive failure.
In terms of backup and restore, it is compatible with most backup software and can be integrated into a backup infrastructure with ease. The hard drive can be used as a target for backups, and the data can be restored to the hard drive or to another location. It is also compatible with various backup protocols such as NDMP, CIFS, NFS and SMB.
It’s worth noting that it’s important to regularly test and verify the integrity of your backups to ensure that they can be restored successfully in the event of data loss.
High-Speed Data Transfer
The Western Digital Ultrastar DC HC550 20TB hard drive (model number WUH722020BL5204) is a high-capacity, enterprise-class hard drive designed for use in data center environments. It features a storage capacity of 20TB, a rotation speed of 7.2K RPM, and a SAS (Serial Attached SCSI) interface with a 12 Gbps data transfer rate.
The SAS interface and 12 Gbps data transfer rate provide faster data transfer speeds than SATA, which can improve the overall performance of the drive. The 512MB of cache on this drive also helps to improve performance by allowing the drive to store frequently accessed data for quick retrieval.
In terms of reliability, the Ultrastar DC HC550 has a high MTBF (Mean Time Between Failures) rating of 2.5 million hours, which makes it suitable for use in high-availability storage systems and servers. Additionally, it features advanced power management technology that helps to reduce power consumption and lower operating costs.
The drive also uses 512e format, this format uses 4K Advanced Format technology and emulates 512 bytes sectors with the use of 512-byte emulation (512e) sector size, this allows the drive to work seamlessly with legacy applications and operating systems that were built for 512 bytes sector size.
