The new 2023 Western Digital Gold 22TB Enterprise Hard Drive
The 22TB WD Gold is a specialty hard drive that has unique advantages in terms of performance and reliability, but it is not for everyone. It is best for multi-HDD storage solutions with specific needs that can benefit from its OptiNAND and ArmorCache technologies. It is not for raw storage or single-drive systems. It is also very expensive compared to other hard drives or SSDs.
WD's Hard Drives Categorization
Western Digital has a simple way of categorizing its hard drives by color. Green, Blue, and Black are the consumer lines, with Green being the most energy-efficient, Blue being the most balanced, and Black being the most performance-oriented. Gold is the enterprise line, with the highest capacities, the fastest transfer rates, and the most advanced features. There are also other colors, like Purple for surveillance systems and Red for network-attached storage (NAS). These are more specialized products that have some similarities with Gold, but also some differences.
If you are looking for a high-capacity, reliable and fast hard disk drive (HDD) for your enterprise needs, you might want to check out the WD Gold HDD series. This is not your typical hard drive, but a specialty product that uses OptiNAND and ArmorCache technologies to deliver exceptional performance and reliability. However, this also means that it is not suitable for everyone, and you should know what you are getting into before you buy it
Gold - WD's Flagship Product
The 22TB WD Gold is the highest-capacity hard drive available right now, and it is also the first one to use WD's OptiNAND-based ArmorCache technology. This is a unique feature that uses a small amount of NAND flash memory to store metadata and improve performance. The metadata includes information about the location, size, and status of the data blocks on the hard drive. By storing this information in NAND flash memory, which is much faster than magnetic disks, the 22TB WD Gold can reduce latency, increase throughput, and enhance reliability. The 22TB WD Gold also has a high sustained transfer rate of 282 MB/s, which is faster than any other hard drive on the market.
WD Gold Optimized for Specific Applications
However, the 22TB Western Digital Gold is not meant to be used as a standalone storage device. It is optimized for specific applications and workloads that require high performance and reliability in multi-drive configurations. For example, it is ideal for data centers, cloud storage, video production, big data analytics, and artificial intelligence. It is not ideal for general-purpose storage or backup, or for single-drive systems. For those use cases, you might be better off with a lower-capacity Black or Blue hard drive, or an SSD.
The 22TB WD Gold also has a premium price tag that reflects its premium features. It costs more than any other hard drive on the market, and more than some SSDs as well. There are some alternatives to the 22TB WD Gold that offer similar capacities at lower prices, but they do not have the same technologies or performance. For example, WD's own Purple Pro and WD Red Pro also have OptiNAND technology at 22TB, but they do not have ArmorCache and they have lower transfer rates of 265 MB/s. They are also more suited for surveillance and NAS applications, respectively. Seagate also has its IronWolf Pro and Exos X22 hard drives at 22TB, but they do not have OptiNAND or ArmorCache either.
What is ArmorCache and why does it matter?
ArmorCache is a technology that WD developed to enhance the performance and reliability of its HDDs. It uses a combination of DRAM, flash memory, and a custom controller to optimize the data flow and metadata management. Metadata is the information that describes the data on the disk, such as file names, sizes, locations, etc. It is essential for the proper functioning of the file system and the applications that access the data.
The benefits of ArmorCache are especially noticeable when the drive is used in write cache enabled (WCE) mode. This mode allows the drive to use its DRAM cache to improve write performance, but it also increases the risk of data loss in case of a power failure. With ArmorCache, this risk is eliminated, as the flash memory preserves the data from the DRAM cache until power is restored. This means that you can enjoy faster write speeds without sacrificing data integrity.
The 22TB Gold HDD's Configuration
The 22TB Gold HDD has 512MB of DRAM cache and 128MB of flash memory (iNAND) on board. The DRAM cache is used to buffer the incoming and outgoing data, while the flash memory is used to store the metadata and some of the data from the DRAM cache in case of a power loss. This way, the drive can recover quickly and resume normal operation without losing any data or compromising performance.
The flash memory also enables a feature called OptiNAND, which is a set of algorithms and functions that improve the efficiency and reliability of the metadata management. OptiNAND reduces the amount of DRAM needed for metadata, freeing up more space for data caching. It also improves the error correction and recovery capabilities of the drive, as well as the compatibility with different file systems and operating systems.
How does the 22TB Gold HDD compare to other drives?
The 22TB Gold HDD is one of the highest-capacity HDDs on the market today. It uses nine platters with helium-sealed technology to achieve this impressive density. It also has a rotational speed of 7200 RPM and a SATA 6 Gb/s interface, which enable it to reach up to 291 MB/s of sustained transfer rate.
The drive is designed for datacenter environments, where reliability, durability, and performance are paramount. It has a mean time between failures (MTBF) rating of 2.5 million hours and a workload rate limit (WRL) of 550 TB per year. It also supports various features such as vibration protection, thermal management, encryption, and secure erase.
The 22TB Gold HDD is ideal for applications that deal with large amounts of data, such as big data analytics, cloud computing, video surveillance, backup, and archive. It can handle mixed workloads with high read/write ratios and large transfer sizes. It can also deliver high random write IOPS thanks to its ArmorCache technology.
The 22TB Gold HDD is currently the only model in the WD Gold series that has ArmorCache technology. The other models range from 1TB to 18TB and have similar specifications, except for lower capacities and smaller DRAM caches. They are also reliable and fast drives, but they do not have the same level of performance and protection as the 22TB model.
The WD Gold HDD series is a great choice for enterprise customers who need high-capacity, reliable, and fast HDDs for their data-intensive applications. The 22TB model stands out from the rest with its unique ArmorCache technology, which enhances its performance and reliability even further. If you are looking for an HDD that can handle heavy workloads, deliver consistent performance, and protect your data from power loss, you should consider getting the 22TB Gold HDD from WD. If you are looking for a hard drive that can handle the most demanding applications and workloads in multi-drive environments, you might want to consider the 22TB WD Gold. The 22TB WD Gold is a specialty hard drive that has unique advantages in terms of performance and reliability, but it is not for everyone. It is best for multi-HDD storage solutions with specific needs that can benefit from its OptiNAND and ArmorCache technologies. It is not for raw storage or single-drive systems. It is also very expensive compared to other hard drives or SSBut if you are looking for something else, you might want to look elsewhere.
