Iometer 2008.08.18 (Read Transfer)
For the enthusiast crowd and enterprise, I have included IOMeter which allows for configurable cache sizes. We have set the test file to 8gb, so you are seeing the results basically without cache leverage. The first is sequential bandwidth (1898 mb/s) tested with a 64mb file and 128 queue depth.
The second is the 4k random speed with a queue depth of 1.
EVEREST AIDA64 DISK BENCHMARK
As a matter of course, we will run the Everst Latency measurement to test the latency of the device. As well, a great characteristic of hardware RAID cards is that they don’t drain the much needed CPU resources of your computer. It just doesn’t get better than zero usage! In contrast a motherboard RAID would cost you CPU power, but the RAID card does all the calculations itself.
The Areca gets extremely good latency, due in part to being on the PCI-e bus. In general RAID cards will receive better latency than drives on onboard motherboard raid, and this holds true here:
