HGST Launches 10TB HDD for Archive Applications

HGST has launched a new 10TB enterprise hard drive that leverages both their helium sealed-drive technology and shingled magnetic recording (SMR) to deliver a new storage solution designed specifically for active archive applications. The HGST Ultrastar Ha10 SMR HDD, as it's called, leverages host-managed SMR which enables the deepest of integrations with solutions providers who control their own software stack. While generally limited to the largest of data centers today, applications that can support large capacity SMR drives are certainly on the rise and should see more widespread adoption as the need to store larger data sets continues to accelerate. SMR has benefits in use cases where data is sequentially written but randomly. HGST is targeting social media, cloud storage, online backup, life sciences as well as media and entertainment with the Ultrastar Ha10.

Seagate Enterprise Performance 10K HDD Review

The 8th generation Seagate Enterprise Performance 10K 2.5" HDD allows data centers to keep up with the rapid growth in data all the while offering low power consumption. The 10k.8 drives are optimized for write-intensive applications such as mission-critical servers, external storage arrays and power- and space-constrained data centers as well as with enterprises with compliance or data security initiatives or those looking to migrate from a 3.5-inch drive form factor system to the 2.5inch next-gen technology. In addition, Seagate offers a TurboBoost model, which helps to accelerate I/O operations and to optimize response times in order to complete additional transactions at a faster rate. The Seagate Performance 10K.8 comes in capacities up to 1.8TB, and while it is more than the previous 10k.7 version and triple the storage pool of the 15K version, it still is much lower than most other enterprise drives out there. That being said, the Seagate Enterprise Performance line of HDDs certainly offers higher performance than the company's previously released hybrid drives.

HGST Ultrastar Helium He8 8TB Enterprise Hard Drive Review

Back in September 2012, HGST first announced their Helium Hard Drive Platform. The Helium drives began to ship the following year in November and as of last month, HGST has deployed over a million drives. We had previously reviewed the Ultrastar He6 6TB helium drive. Now HGST has taken their helium technology and expanded capacity even further with the Ultrastar Helium He8 8TB Enterprise Hard Drive. The He8 is available in either SAS 12Gb/s or SATA 6Gb/s interface. The drives offer a spindle speed of 7,200RPM, on disk buffer of 128MB and drive sustained throughput of 205MB/s.

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.
