Methods of SMR Data Management

SMR uses a mapping system for LBAs that want to get written randomly to only writing them sequentially. Similar to SSD’s Flash Translation Layer (FTL), SMR HDDs use what is sometimes called a SMR (or Shingle) Translation Layer (STL), which is a similar concept. With SMR, however, much more is to be gained by making the host aware of the underlying SMR technology. The industry is in the final stages of the standardization process for SMR with ZBC (Zoned Block Commands) being the standard for SAS and ZAC (Zoned ATA Commands) being the standard for SATA. These standards define a Zoned Block Device in which the LBA space is divided into independent Zones. Within each Zone, writes should be sequential. In order to overwrite data, it is necessary to first reset the zone, similar to an erase block in an SSD. What happens when non-sequential writes are sent to a Zone varies depending on the type of SMR implementation.

Seagate Archive HDD Review (8TB)

The Seagate Archive HDD represents several major advancements in hard drive technology for the company. First, the massive 8TB capacity is Seagate's highest to date. Second, the methodology to get to that 8TB is new to the market. Seagate uses Shingled Magnetic Recording (SMR) to change the way tracks are laid out on the platters, which drives higher platter density. This new series of Archive HDDs isn't a general purpose drive however, that duty is aligned with the Enterprise Capacity family. In this case, as the name implies, the drives are intended for use in large-scale data centers where density, power consumption, data integrity and data retrieval are paramount.
