I hear you and the others on the storage front, but I think the storage issue with the new Mac Pro is the least of it's problems. I mean seriously, anyone complaining about the cost of moving storage external has not been over to Amazon lately. This is just one of many adjacent pairs of drives with similar price similarities/differences I found... (see attachment)
Yes, if my office caught on fire and burned to the ground such that I'd have to buy everything new, the cost impact (via Amazon) wouldn't be so horrible.
But that's not the typical lifecycle / Total Cost of Ownership.
And sure, multi-bay TB RAID enclosures are pricey,...
Indeed, which is why the question isn't merely cost, but the: "What I would need to spend TODAY just to do a transition?" lifecycle economics.
You're correct that RAID arrays >10TB aren't wise ... that's why I don't have any that large. For a simple transition of my current MP, I'd be looking at having to buy at least two of those pricey TB RAID enclosures...the two additional RAIDs that are on my externals can get away with the $30 TB-FW800 adaptor.
FYI, the legacy storage can't rely too much on USB3, because there's also other preexisting hardware investments that need connectivity, such as printers, scanners, card readers, cameras, etc.
Without any disrespect, I just really have a hard time buying all this complaining about external storage as a legitimate financial hardship. It sounds more to me like a reluctance to change.
Sorry, but that's still not really seeing the point. The point isn't necessarily merely how much "Total" money is involved in as much as when that it must be spent.
What's been far more typical (right or wrong) is that during the life of a desktop system, there's incremental adds in capability (here: storage capacity) ... and then when the desktop itself has reached EOL and needs to be replaced, some of that capability can move forward onto the new system, so that it gets the remainder of its effective lifespan consumed, rather than discarded prematurely.
With the nMP, this lifecycle management model breaks: its lack of storage accommodation incurs a front-loaded expense, so instead of the annual budget having a modest bump for just a new system, there's also the replacement cost of now-'incompatible' storage capacity too: the sum of the two cause a "bubble" in the IT budget.
The impact on the IT budget is that money that used to be able to be spread over a few years ... can't, at least for this transition. Even if the three year costs work out to be exactly the same, that bubble is still a barrier to adoption.
-hh
PS (EDIT addition): the sticking point on a lot of this revolves around how the nMP differs significantly from prior technology updates: Apple did not afford its customers any "bridge". Thunderbolt wasn't offered on the old MP systems prior to the nMP system which simultaneously deleted the traditional internal expansion capabilities (legacy), forcing an immediate transition expense to TB. And what is most frustrating about it is that we knew that TB was Apple's Road Map, but we could do nothing to parepare for this change.
