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.

    Those numbers are pretty low. I think the 850 Pro outdoes that on every level.

    and has the 10 year warranty to boot

    But the 850 Pro doesn't have "Cloud" and "Ultra" in the name, so it's not trendy enough :p

    It has "Pro" in the name, which makes it good for me. :)

    these drives will have 1-20PB of Write endurance warranty depending on size of SSD and DWPD rating (the 850 pro is what 150-300TB? but seems good all the way up to 2PB if you ignore warranty on the Pro drives)

    Are those IOPS peak or steady state ? They are more READ optimised for archived data not WRITE intensive uses.

    no manufacturer posts steady state benchmarks..
