Thank you for your revealing response. I appreciate it.

Your limitation in speed is the current Thunderbolt buss.
How do I have to understand this? I think Thunderbolt is capable to insure transmission rates up to 10Gb/s(~1.25GB/s). Aren’t the HDDs with it’s 600MB/s the limitation? Or do you mean the lag of accessing files via bus per se compared to internal drives? Until now I wasn’t able to test the real power of Thunderbolt – only wasted to single 5400rpm-Drives.

If you ask the question "how can I have something like this for $500 ?" - you can't.
When i started thinking about a decent storage solution, I thought into the blue about spending 4000€ (~5500$). The idea of a Low-Cost-Model came in useful when I read about the Pegasus.
Of course I ran intro somethink like the ‘A08S-PS’:

But I can not see the advantage to invest so much more money. Please correct me if I’m wrong – I would if it is worth it. Anyway, the big advantage of this setup may be the possibility to upgrade to a second A08S-PS in the future and double the performance connected via PCIe HBA Card with Dual Port. Could I also achieve a performance boost by adding another Pegasus via Thunderbolt?

I would avoid Seagate drives, and go for HGST or Western Digital.The problem is that neither HGST nor WD ist on the promise compatibility list. I think using this HDDs will lead to a loss of warranty. Do you have bad experiences with seagate drives?

If you are on a budget, you can't beat a price like this.
Would you give me a hint in which direction I should inform myself without the limitation of a ‘low budget’. I’m overwhelmed by the number of good deals I have found in my recherche.

The problem is that I need to render image-sequences from AE due to the fact that I can rerender certain parts of the sequence. I would hate to loose this advantage.
