don't forget Sandisk
I saw the 1 DWPD number and was wondering what Sandisk offers, on the HP 3PAR flagship 3.84TB SSD from Sandisk, the Sandisk specs say 0.5 DWPD under transactional workloads. Though HP backs that with a 5 year unconditional warranty. The previous cMLC 1.92TB SSD under 3PAR HP says you'd have to write 8PB of data to it before it wore out (which is pretty impressive to me compared to the 150TB on my Samsung consumer 850 Pro)
"Flash SSD endurance is significantly enhanced as a result of HP 3PAR StoreServ Flash Storage distinctive “Adaptive Sparing” that unlocks the hidden capacity present in each flash SSD. Unlocking that hidden capacity permits the HP 3PAR StoreServ Flash Storage to utilize that spare capacity as additional over-provisioned capacity. This is what enables HP to convert a SAS SanDisk 3.84TB read optimized flash (SSD) to being both write and read-optimized and guarantee a 5 year warranty if it ever wears out."
(Dell recently announced 3.84TB SSDs but I am unsure if they are supported for write optimized workloads or not, since Dell does not have technology similar to Adaptive sparing that I know of)
So even with 1DWPD, if you have the right kind of storage tech surrounding that SSD you can get quite a bit more out of the drive then you might otherwise expect.
