Western Digital releases new enterprise-level products: its first Gen5 solid-state drive and 32TB mechanical hard drive, tied for the largest capacity

According to news from this site on June 8, Western Digital recently released hard drive products that are part of its Ultrastar DC data center storage product line.

This batch of new products includes Western Digital’s first PCIe Gen5 solid-state drive DC SN861 and the industry’s largest capacity 32TB enterprise-class mechanical hard drive DC HC690.

Ultrastar DC SN861

Ultrastar DC SN861 is Western Digital’s first PCIe Gen5 enterprise-class solid-state drive. The DC SN861 has made great strides in random reads, with a maximum rate three times that of its predecessor, the DC SN655.

Western Digital said that DC SN861 has ultra-low read and write latency and "incredible" responsiveness, can provide LLM training, inference and AI Service workloads provide best-in-class performance and energy efficiency.

DC SN861 supports NVMe 2.0 and OCP 2.0 protocols, and is available in three form factors: U.2, E1.S and E3.S, with capacity covering 2~ The 16TB level includes two endurance levels: 1DWPD and 3DWPD.

Currently, the Western Digital official website has launched the parameter information of some 2~8TB SKUs of Ultrastar DC SN861. This website has compiled the parameters of the 6.4TB 3DWPD U.2 version as follows:

##Random performance3000K IOPS750K IOPS10μs

DC SN861	Read rate	Write rate	Latency
Sequential performance	13700MB/s	7500MB/s	70μs

Western Digital says the

E1.S version of Ultrastar DC SN861 is now sampling. The U.2 version will be sampled this month and shipped in batches in the third quarter. More information on the E3.S version and E1.S version will be released later this year. .

Ultrastar DC HC690

After Seagate took the lead in launching the 32TB mechanical hard drive, Western Digital also released its corresponding solution, Ultrastar DC HC690.

DC HC690 adopts ePMR magnetic recording mode and is equipped with Western Digital’s

UltraSMR and OptiNAND technologies.

Western Digital says the Ultrastar DC HC690 is sampling now to select enterprise customers, with more details to be announced later this summer.

Ultrastar SN655+ and high-capacity solid-state drive roadmap

Western Digital also launched Ultrastar SN655+, which is a larger-capacity version of its PCIe Gen4 enterprise-class solid-state drive DC SN655,

Can provide capacity up to 64TB in U.2 form factor.

Western Digital said Ultrastar SN655+ is now sampling and will be shipped in batches in the third quarter of this year.

Western Digital also disclosed its roadmap for high-capacity enterprise-class solid-state drives. After launching a 64TB product this year, Western Digital plans to

launch a 128TB product in 2025 and by 2027 The capacity is doubled again to 256TB.

Western Digital also looks forward to the long-term 1PB ultra-high-capacity enterprise-class solid-state drive.
