About this product
The Seagate Exos X20z HSMR is an 18TB internal 3.5-inch hard drive featuring Host-Managed Shingled Magnetic Recording (SMR) technology. Designed for specific applications where its recording method can be optimally managed, it connects via a SATA III interface. This HDD offers a large storage capacity, making it suitable for archiving or certain data center workloads. It requires host-level awareness and management for efficient operation.
Our take
This 18TB Seagate Exos X20z offers a huge amount of storage for its price, but it's crucial to understand it's a Host-Managed SMR drive. This isn't a plug-and-play solution for every use case. While SMR allows for higher density, performance can drop significantly with heavy random writes, as the host needs to manage the shingling process. For archiving or write-once, read-many scenarios in a compatible system, it's a great capacity bargain. However, if you need consistent write performance for active data, you might want to look at CMR drives instead. Definitely 'READ FIRST!' as the title suggests.
