NAS group is planned for non-linear editing. There is a question about choose between hardware RAID or sitovym ZRAID. It would seem that the choice in favor of hardware RAID is obvious, but I don't think so. Here's why: hardware RAID takes care of all dispatching functions and optimize the operations of reading record. The same function performs ZRAID, but it uses the main system resources: CPU and memory. In the case when the system is loaded with applications is a strong argument in favor of hardware RAID, but if the system does not execute any application, in addition to the file server, it is not critical. Moreover, in this case (software RAID) to perform the functions of management and optimization of read/write and more resources — CPU and more memory.
Performance interfaces, I / o (i.e. NAS, DAS or SAN) believe it is unimportant, as 10G Ethernet removes the bottleneck at the transmission interface. Total, to build a productive file server use what technology gives the best performance metrics, namely access time to a random file with high number of appeals?
P. S. I Understand that the question a lot of defaults, but it is important to understand what aspects I have not considered in their arguments.
Yeah about the same, especially for such tasks as installation, where a linear reading.
There is greater need to think what to do if the RAID controller dies, or is there a disconnect electricity when writing to the disks.

Oh! It did so, it is important, and that sequence, then it is clearly for one person, but when 5 people are cut from the same array, the question of access time climbs to first place.
