Western digital announces new 7.68 tb hgst ultrastar ssd
Table of contents:
Western Digital this week announced two families of high-performance HGST Ultrastar SSDs, designed for high workloads in server and hyperscale environments that require immediate response times. The new units will act as application accelerators and therefore offer fairly high sequential and random performance.
New HGST Ultrastar SSDs, the SN200 and SN260
Western Digital introduces two models of HGST Ultrastar SSDs, the SN200 and the SN260. Both disks are NVMe 1.2 compliant, use the PCIe 3.0 interface, and support "advanced ECC" (which is probably a marketing way of saying LDPC).
As for the Ultrastar SN260, it is designed to offer superior performance, uses the PCIe 3.0 x8 interface and is available in card format. In contrast, the Ultrastar SN200 uses a traditional 2.5 "/ 15mm disk design in conjunction with a dual-port U.2 connector with a PCIe 3.0 x4 interface.
On either model, there will be a wide variety of capacities, ranging from a modest 800GB to 7.68TB.
The HGST Ultrastar SN200 is considerably slower than the SN260, in sequential and random reads, but the write performance of the two drives is similar. The SN200 SSD supports sequential read speeds of up to 3, 300 MB / s, as well as sequential write speeds of up to 2, 100 MB / s. In the case of the SN260, the sequential write speed is 6100 MB / s.
