Bb-b-b-but the SSD write endurance!!! We need more information on SSD endurance because this is the only spec that 99% of users will be able to see and be affected by on an average day!!
Please buy (can't have those cherrypicked samples) 1000 (sample size of 1 isn't good enough to illustrate a statistical average, even 1000 is small) of these pricey datacenter SSDs so you can do in-depth SSD endurance testing over the course of 4+ years before publishing results, after which I would've already bought something newer and better!!
Aaaghhrrrhrrr... Why is it so hard to get real world SSD endurance numbers!?!! My SSD could die 3 seconds from now, or it might just be obsoleted by new hardware less than 6 months from now. Knowing SSD endurance numbers beforehand allows me to circumvent proper data backup processes by backing up my data the hour right before my SSD dies according the real world(tm) endurance testing.
Oh whoops is my sarcasm showing? Did I beat all the SSD endurance nerds to the comment section?
For the same reason why misinformed people spend needless amounts of time worrying about "real world(tm)" endurance numbers and waste their breath in comment sections trying to get worthless numbers for their potential purchase of 1 (read: ONE) storage drive purchase.
The fact of the matter is, if your data's important, then regardless of the point of failure (such as the endurance of NAND flash wearing out, or even a drive head scratching the surface of a disk) of the storage device (HDD, tape, SSD, a flash drive, SD card, whatever) proper data retention procedures should have mitigated not only any loss of data, but any downtime incurred by a failed device. The endurance rating of an SSD is absolutely irrelevant to anyone except for the tier 1 data storage services (cloud platforms like AWS, DropBox, CloudFlare, etc.) and to these people, they have the money and internal resources to document the relative reliability of any drives they're interested in purchasing according to their real world use cases. The only reason why these tier 1 data storage services care is that the endurance of these datacenter tier devices directly correlates to uptime and availability of their system and the time spent changing drives out and rebuilding storage arrays. They can do the cost-benefit analysis of buying some drives, documenting whatever value they have, and proceed with ordering more if they're a good fit. They're literally making a living making sure that data's available. Chances are, any SSD you're interested in purchasing isn't making you $$$.
The impetus of DWPD or other endurance metrics were never a frequent point of discussion for mechanical hard drives. And they still aren't. For personal use, the only thing that really matters is price, storage capacity, and warranty. Reliability is mitigated by proper data backups. If a drive dies, just contact warranty and grab the latest backup you have.
NAND flash endurance means nothing because all storage devices have a MTBF where your data is lost either way (even if the controller, rather than the NAND flash, dies), so it's impractical to care about just one facet (NAND endurance) that could lead to loss of data when you should be mitigating against ANY data loss by proper backup procedures.
I wonder what happened to those people in reality. They probaby can't go out before checking the pollution level outside. Someone did something wrong and created fragile human beings that need higher percentage of certainty in their live.
0.2 DWPD is pretty awful so you'd better have done your homework on your storage needs before buying. On the other hand the V-NAND looks like it has some serious potential as a replacement that has good endurance. I hope it finds its way down to the consumer market to give Optane some competition. I've already hit endurance limits on crappy TLC so I'm not looking forward to CE QLC SSDs that are now entering the retail space.
The Intel 660p is only 100 bucks for 500GB. Don't buy it if it doesn't work for you, but that price is insanely low vs the $168 for the Samsung 970 EVO.
I think the 0.2 DWPD is mainly for things like Netflix Streaming Appliances, which often hold the same popular episodes day after day, and a good cheap fast 4TB SSD can still serve more concurrent customers-per-dollar than spinning HDD -- and end up being cheaper than HDD-per-stream due to the ability to stream to many more customers concurrently. The Appliances have excellent failover capabilities, so a failed disk gets streams from another adjacent Netflix Appliance, and they auto-clone stream copies to faster disks if the streams are popular.
I would like to see that 983 ZET in a U.2 form factor besides just an add-in card. I have a few servers that I would like to populate with those drives, and U.2 is more available now than the Ruler/EDSFF/NF1 form factors.

why did you waste so much time typing this out?Also why did I waste time logging in just to ask you that >:(

That is a weird-ass lineup. Nothing between 0.8 and 8.5 DWPD and the latter have super low capacity.....abufrejoval - Friday, September 7, 2018 - link
Well, it's logical on a physics level with MLC missing between SLC and TLC. Sometimes marketing cannot hide physics after all: Fine with me.saiga6360 - Wednesday, September 5, 2018 - link
Well, that's SLC vs TLC 3D NAND. SLC is the write endurance gold standard but at a higher cost and low capacities.romrunning - Wednesday, September 5, 2018 - link
