As a use-case example, those units have been in use for at least ten years by CCP Games [http://community.eveonline.com/news/news-channels/press-rele... and http://community.eveonline.com/news/dev-blogs/apocrypharrrrr...] as extreme-low-latency database storage for a fairly large cluster. At the time there were jokes of the staff needing to get special clearances just to see demo hardware before making their decision and eventual purchase due to restrictions related to their use by government and military customers.
Maybe I'm oversimplifying it or looking at it wrong, but I wanted to share my 2c while I was thinking about it. I'll take a better look later.
We have in less then a decade, all of a sudden remove most of our I/O bottleneck. From NAND SSD, to Intel Xpoint, and Giant amount of memory all within 10 years.
If I have a write-heavy application, for instance a time-series database, does it mean that eventually I'm going to consume all the RAM, then page cache, and eventually my throughput is going to be disk IO bound?
