Proprietary gel architecture
Hitachi/HGST was the first manufacturer of helium HDDs on the market and now rightfully leads the industry. The Ultrastar He10 model uses the third generation of the HelioSeal architecture, which relies on the company's disc sealing method. Instead of the controversial but increasingly popular "tiled" writes, the old-fashioned drive relies on PMR and caching technologies to improve random write speeds. An older model with a volume of 10 TB came to us for testing, which includes 7 plates and 14 heads, and the spindle speed is standard for this class of 7200 rpm. Connection options are SATA and SAS.
Unusual caching principle
The fun doesn't end with gel architecture. Hitachi/HGST were the first to pull off an interesting trick with a new caching technology. It consists in dividing the hard drive into small cache zones that save data in the event of a power outage and allow the recording heads to move less. This made it possible to more efficiently concatenate many small write operations before committing the data to persistent storage. Profit: Improved energy efficiency, increased reliability of data storage with increased speed of write operations. For example, during sequential reading, it gives out an average of 249 MB / s, although earlier such speeds were the prerogative of 2.5-inch server hard drives with a spindle speed of 15,000 rpm such as Seagate Savvio. But with write-oriented operations with random access, the disk shows variable results, but, in fairness, such tasks are rarely set before server ones.
SED and ISE support
The rest of the Ultrastar He10 is not much different from a standard server HDD: MTBF of 2.5 million hours, a five-year warranty. The drive is also equipped with Self-Encrypting Drive (SED) for self-encrypting data and Instant Secure Erase (ISE), which allows you to destroy all data on the drive with just one command when decommissioning it. What's especially cool is that when it was released in 2016, the Ultrastar He10 was either expensive or very expensive. But since then a lot of water has flowed under the bridge, the price has stabilized and now it even stands at the level of the popular Seagate Exos and IronWolf series.
