Description
More Features
The Western Digital Ultrastar DC HC550 18TB hard drive (model number WUH721818ALE6L4) is a high-capacity, enterprise-class hard drive designed for use in data center environments. It has all the features that the WUH721818ALE6L1 has, in addition to the following features:
- Helium Platform, this platform uses Helium which is denser than air, to reduce the turbulence caused by spinning disks, this leads to less power consumption, less vibration and better performance.
- 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.
- ASE (Automated Storage Tiering) ready, this feature allows the drive to work with software that can move data between different types of storage tiers based on usage patterns, this helps to optimize storage capacity and performance.
It’s worth noting that the drive still uses a SATA interface, which is slower than SAS and is primarily used in consumer-grade devices such as personal computers, but the additional features such as Helium Platform, 512E format, and ASE ready make it suitable for enterprise-grade storage systems.
High-Speed Data Transfer
The Western Digital Ultrastar 18TB 7.2K RPM SATA-6GBPS 512MB Buffer 512E SE 3.5inch Helium Platform Enterprise Hard Drive (WUH721818ALE6L4) is designed for high performance and large-scale storage applications. The 512MB buffer and 7200 RPM spindle speed allows for fast data transfer rates, and the 512E sector format increases the hard drive’s capacity and efficiency. It also uses Helium Platform which provides improved power efficiency, and it’s ideal for high-density storage environments.
It’s also built to handle heavy workloads, with a MTBF of 2.5 million hours and features such as load/unload head technology, which reduces wear and tear on the hard drive’s moving parts. It also supports advanced power management options to help reduce energy consumption and prolong the life of the drive.
Therefore, it is ideal for data centers, video surveillance, cloud storage, and other high-performance enterprise applications.
Backup & Restore Facilities
The Western Digital WUH721818ALE6L4 is an 18 terabyte (TB) hard drive with a rotation speed of 7,200 revolutions per minute (RPM), uses the SATA interface and has a data transfer rate of 6 gigabits per second (GB/s). It has a 512MB buffer, and utilizes the 512E (512 emulation) sector format and is a 3.5-inch form factor. It is designed with a Helium platform for enterprise use and is compatible with a variety of systems and devices that support the SATA interface and can use 3.5-inch hard drives. It is typically used for data storage and backup in data centers and other enterprise environments. It is suitable for large-scale data storage, archiving and backup applications, as well as for use in storage arrays and servers.
