Available rackmount NAS: gse pro 1004 Infortrend or synology RS815+?

Need the most affordable rackmount NAS 20TB on each point. Full of the cheapest SATA drives. Disks, of course, want to put separately. Now compare synology RS815+ and infortrend gse pro 1004. They are about the same. And who really is the performance is better, and why it depends? For example, Infortrend said that their NASA hardware RAID, and other software. What does it mean?

And who really is the performance is better, and why it depends?
It is impossible to say who of them is better performance for the simple reason that performance depends primarily on tasks, and only the second of the characteristics of the devices themselves.
If you shovel soup slurp, the performance will be much lower than a traditional spoon.
But if you shovel to make a hole - then the productivity of the shovel will be significantly higher than the spoon.


Infortrend said that their NASA hardware RAID, and other software. What does it mean?
This means that in one case, the calculations for the RAID makes a processor that is soldered on the Board for RAID, otherwise these calculations the program does using CPU resources.

Hardware RAID is when all processing operations for a RAID is a special processor of the RAID controller separate from the CPU. This off-loads the CPU, allowing it to deal only with "command".
Software RAID is when all the calculations the CPU does. Synology have 100% RAID software. The presence of hardware RAID significantly increases the cost of construction, so it's possible INFOtrend the same RAID software.

What usually have to pay by buying a shelf without discs?

I think for the iron? Yes no, from the point of view of iron - bedraggled office computer, if it to poke 4-port network card, simply to cover the shelf. Pay for the software.

Yes, for this very shell that provides a shelf, which is Linux, a human face. Nobody of course bothers to connect to it via ssh, put optware and the drag, but these people don't buy the shelves :D

Infortrend GSe Pro is something new. Hardware RAID (if it has one, Infortrend Gse) improves system performance for backup and recovery, particularly for older hardware with limited computing power, adding cache memory to the DRAM system. Reduces the system load when burning backups and reduces downtime when restoring data. Adds option of RAID, which otherwise may not be available using only the motherboard such as RAID 5/6, which allows one and two disk failures. A separate hardware RAID protects against data corruption resulting from the loss of power in the backup process.
