SanDisk Announces Second Generation CloudSpeed Ultra SATA Enterprise SSDby Billy Tallis on August 11, 2015 5:00 PM EST
At Flash Memory Summit today SanDisk announced the second generation of their CloudSpeed Ultra enterprise drive. This is the sibling to the gen. 2 CloudSpeed Eco that was announced in June.
As with the Eco gen. 2, the Ultra gen. 2 transitions from 19nm to 15nm MLC and brings a reduced endurance rating but increased performance. The Ultra model continues to be geared for mixed read/write workloads while the Eco is for more read-intensive uses.

SanDisk is already supplying the CloudSpeed Ultra gen. 2 to several major customers for large-scale deployments and it will be more broadly available later in 2015, where it will be competing against drives like Samsung's SM863 and Intel's DC S3610. Pricing will be under $1/GB, but we don't know by how much. It probably won't be undercut by Intel's DC S3610, but to be competitive it will need to be down near Samsung's $0.66/GB for the SM863.
