HGST has announced additional solid-state drives (SSDs) for the data centre, offering a spread of price and performance options for customers that balance write endurance, write performance and cost, with capacities up to 1.6TB.
Available now, the new high-performance Ultrastar 12Gbps serial attached SCSI (SAS) SSD family supports applications requiring fast and reliable data storage, such as online transaction processing, cloud computing, online gaming and big data analytics, the firm said.
The new drives comprise three separate lines targeting write endurance, write performance and read-intensive applications, in the form of the Ultrastar SSD800MH.B, Ultrastar SSD1600MM and Ultrastar SSD1600MR, respectively.
Thus the Ultrastar SSD800MH.B is capable of sustaining up to 25 full random drive writes per day for up to five years, and is available in capacities of 100GB to 800GB.
Meanwhile the Ultrastar SSD1600MM is rated at up to 10 full random drive writes per day for five years, and offers capacities of 200GB to 1.6TB, while the Ultrastar SSD1600MR is just two full random drive writes per day for up to five years but supports capacities of 250GB to 1.6TB.
HGST contends that SSDs will not replace hard drives in the near future, but that enterprise storage architectures will instead use a mixture of disk types to form tiered storage based on the respective strengths and cost of ownership of each type.
Ulrich Hansen, vice president of SSD product marketing, said: “HGST is in a unique position of offering a complete enterprise storage portfolio with leading solutions in both product categories.”
He claimed that HGST leads the industry in SAS SSDs, and that this type continues to be the preferred storage building blocks for server and storage systems that support a growing set of data-intensive enterprise applications.
The new drives are based on Intel’s enterprise-grade 20nm multi-level cell (MLC) Nand flash memory chips, which means that they excel in key cost of ownership metrics including transactions-per-dollar and transactions-per-watt, HGST claimed.
Earlier this month, HGST launched its Ultrastar C10K1800 line of 10K RPM hard drives, which are designed to complement SSDs and the firm’s 15K hard drives in a tiered storage architecture.
