Samsung Demos PCIe NVMe SSD At 5.6 GB Per Second, 1 Million IOPS (hothardware.com)
MojoKid writes: Samsung decided to show off their latest SSD wares at Dell World 2015 with two storage products that are sure to impress data center folks. Up and running on display, Samsung showcased their PM1725 drive, which is a half-height, half-length (HHHL) NVMe SSD that will be one of the fastest on the market when it ships later this year. It sports transfer speeds of 5500MB/sec for sequential reads and 1800MB/s for writes. Samsung had the drive running in a server with Iometer fired up and pushing in excess of 5.6GB/sec. The PM1725 also is rated for random reads up to 1,000,000 IOPS and random writes of 120,000 IOPS. The top of the line 6.4TB SSD is rated to handle 32TB of writes per day with a 5-year warranty.
Given the endurance test people have peformed against "consumer" SSDs, it sure seems like the expected endurance exceeds the warrant by a lot.

I'd be awful curious to see what the actual durability of an 850 Pro would be in a real production SAN. My suspicion is that the better-than-rated endurance coupled with the low replacement cost might make it worthwhile when you consider the staggering performance you would get.
There might even be gimmicks you could apply on a per-disk basis to improve durability, such as underprovisioning each drive by 25% so that you could wear level across more capacity.
