I can't agree, for a pro single user, the Bluray can be a good solution for archive. I don't think hard drives (NAS, SAS...) are a long term storage that have to be powered on...
There is nothing that changes archival functionality of a blue ray drive if it is external versus internal.
The question of optical drives is whether a large majority of the users who buy the system are going to use it or not. Not whether the could use it, but actual general usage patterns.
In large numbers, folks back-up to HDDs (either local or remote or both). Not tape. Not ODDs.
Sneaker-net file transfers are easy to do on 8, 16, 32GB flash drives.
LTO is good solution but expensive for single pro user.
Again "inside and part of the standard default configuration sold to most" is the real issue. Not whether LTO is a good solution for some users.
The long term archive is a big problem of these days.....
ARCHIVE IS A BIG PROBLEM!
There isn't a "new" problem with archive. The issue is that archives need to be moved or at least integrity checked over time. Since the media will change over time the device size and shape can change over time. With a sufficiently fast external connector that variance of size and shape can be accomodated externally. Also externals can be used on multiple machines by just moving it from location to location.

Yes but i'm talking for low end SINGLE CPU not multiple with great performance/price [/quote]
ECC is more drive by the amount of RAM than the single or multiple CPU packages. The more RAM you have the more likely going to get an error. Just like more disks, increased risk. Double and triple digit GB of RAM make ECC a prudent move.
If data have value then it is worth protecting.
i have 15 workstations with i7 and other 15 with Xeon and i regret to have spend more money in Xeons workstations.
It is likely Apples to Oranges comparisons. The primary difference is not being driven by Xeon / RAM but by functionality and long term performance being tossed by the i7s. Mainstream design i7's have only x16 PCI-e v3.0 lanes. A modern Xeon E5 class has x40.
If workload only really requires a single PCI-e card and relatively low I/O then the i7 is a better fit. But that isn't where the Mac Pro class machines have been primarily targeted.
In Apple's product mix mini and iMacs are targted at single GPU card workloads.
This is an extremely dubious comparison. If comparing single socket Xeon E5 versus i7 then should be selecting a E5 1600 offering. Not a E5 2600 one. That benchmark is just misdirection.
The i7's that are derived from the basic workstation design are the same price as the E5 1600's.
Apple will probably never going to sell a Mac Pro with just one 2600 in it. That is just more than kind of silly. You pay more for a 2600 series so that you can pair them. If pay for the functionality and do not pair they have raised the system price and thrown that functionality out the window temporarily. It just doesn't make any sense as system.
The config is sold by some ( HP , Dell ,etc) as some kind of "future proof" system where later can install a second CPU package to make it a complete system. Apple isn't going to sell something that is incomplete and half done.
