post your hard drive benchmarks :)

hmm areca setup, so its not an ioDrive raid...

2 ARC-1680ix-24s with 36GB drives?
or 2 ARC-1680ix-16s with 73GB drives? that would need a per-drive read speed of close to 200MB/s though so probably not...

those read speeds have saturated the equivalent of 16 pcie lanes, and 1.4TB is achievable with 24 drives each on 2 HBAs. Quite an impressive setup!
(its actually slightly over 16x pcie bandwidth, but not by much... pcie overclock or maybe just due to software aggregation of data in bursts? or 3 HBAs?)

Afaik there arent any x16 pcie or x8 pcie2.0 raid cards... shame...

4gb Fiber Channel based Array enterprise level stuff probably, given that it maintains 4000MB/s i'd say it might be a ramsan?
