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.

dgingeri - Tuesday, August 11, 2015 - linkThose numbers are pretty low. I think the 850 Pro outdoes that on every level.
Morawka - Tuesday, August 11, 2015 - linkand has the 10 year warranty to boot
MrSpadge - Wednesday, August 12, 2015 - linkBut the 850 Pro doesn't have "Cloud" and "Ultra" in the name, so it's not trendy enough :p
dgingeri - Wednesday, August 12, 2015 - linkIt has "Pro" in the name, which makes it good for me. :)
leexgx - Sunday, August 16, 2015 - linkthese 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)
tygrus - Tuesday, August 11, 2015 - linkAre those IOPS peak or steady state ? They are more READ optimised for archived data not WRITE intensive uses.
guntherzssd - Tuesday, August 25, 2015 - linkno manufacturer posts steady state benchmarks..
