Egads, five new pages over the New Years weekend. Hope that ya'll actually took some time off to relax! ;-)
The question should be what does it fail at? I bought a base nMP for video editing. It was overkill for my video editing needs, but I was surprised at functionality as a Video Database. My project has 15TB of video, I use reference videos...My main databases are on two thunderbolt 20TB raid5 drives and the speed and ability I can search through 15TB of video amazes me.
Quoted because my use case also uses a bunch of data.
The compare/contrast that I get when I look at the cMP versus nMP is that the former has a degree of affordable internal storage, whereas the latter requires all storage to be externalized ...
which invariably costs more, especially when on Thunderbolt interface.
Naturally, the storage question will be "how much is enough" in terms of the specific use case, but the counterpoint to this is also the Law of Diminishing Returns: the initial instance of providing
some level of capability will be satisfactory for the proverbial 80% (of the 80/20 rule)...its just a question of
how much is "some"?. In the case of the cMP, the answer was 4 internal 3.5" bays, after which point expansion became more expensive because it then had to be external like on the nMP.
It will be interesting to see if the nMP is actually going a new direction instead of supporting mature technologies. You cannot measure a new tool by old benchmarks.
True, but by the same token, benchmarks aren't static either: they change & adapt to what the new workflow needs are, since their purpose is to be an effective means of informing perspective customer(s).
Insofar as Apple's direction...
With the changes to Disk Utility in OS X 10.11, Apple has chosen to depreciate RAID support. When one then also looks at the overall Mac product lines, they've all now gone to a single internal 'disk' (regardless of if it is HDD or SDD hardware), which is what allows this simplification of their OS architecture to not have to deal with RAID. In essence, that previously in-house capability has been curtailed and one has to now rely on third party solutions. Functionally, this is telegraphing that Apple doesn't intend to offer multi-disk Macs for the foreseeable future (if not 'forever' gone). While this may not necessarily be a bad thing in the long term, what is disturbing ... and anti-business ... is that the move was done despite the fact that the cMP is still officially supported hardware.
