Benchmark Results
The benchmark diagrams are sorted by RAID arrays (RAID 6, RAID 5, RAID 0), followed by the stripe size.
Access Time
Compared to the 14 ms access time of a single Samsung HD321KJ hard drive, which we used for the stripe size tests, all RAID setups show an access time that is almost twice as long. While the access times tend to be longer at 64 kB, the differences are too small to make decisions based on them. The I/O benchmarks, however, show more significant differences.
Interface Bandwidth
Interface bandwidth isn’t an issue for these setups, as none of the configurations really exceeds 400 MB/s. The Areca isn’t optimized only for throughput, as eight hard drives should be able to reach 500 MB/s in a RAID 0 array.
