WDC has announced some new storage products for enterprise users.

The Ultrastar He12 now brings their capacity up to 12TB. WDC claims 2.5 million hours MTBF but we are much too cynical. The disk is available with SAS and SATA interfaces. WDC is looking at HAMR to bump capacity to 16TB by 2018. WDC says it has shipped more than 12 million helium-filled drives to date, and no doubt aims to ship another 12 million as fast as it can.

WDC also announced the Ultrastar-branded SS200 and SN200 products. Each come in capacity-optimised and endurance-optimised variants with one drive write per day (DWPD) and 3DWPD ratings respectively in their five year warranty. The SN200 is an NVMe drive in 2½ inch HHHL add-in card format. It effectively replaces the existing SN100 and has greater capacity and higher speeds. The 2½ inch version has capacities of 800GB, 1.6TB, 3.2TB and 6.4TB in the endurance-optimised version, but 960GB, 1.92TB, 3.84TB, and 7.68TB in the capacity-optimised models.

In the 2½ inch form factor both capacity and endurance kinds have up to 830,00 random read IOPS, 75,000 random write IOPS when capacity-optimised and up to 200,000 when endurance-optimised. The sequential read and write figures apply to both kinds and are 3.3GB/sec and 2.1GB.sec respectively.

WDC competes with Seagate and Toshiba for hard disks and increasingly in the SSD market. We expect to see more product offerings in the next 12-180 months.
