We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: AVADirect, GIGABYTE, Cooler Master, LSI and Noctua.

Today we get a chance to use our Seagate Constellation 2.5" 500GB drives that have been hanging around for a couple of months. For testing the AIC MiniBOD we ran a mixed set of ST9500430SS SAS drives and finished the final four slots off with ST950053NS SATA drives. Other than the interface difference, one being SAS and the other SATA, both drives are from the Constellation Series and the specs are nearly identical.
We chose to test the AIC MiniBOD in two configurations, the first in RAID 0 and the second in RAID 5. Most users of this equipment would and should use RAID 5 or RAID 6 since a drive failure in RAID 0 would cause a total loss of data.
The very powerful LSI 9280-8E was chosen for duty since it features the required external SAS connectors, PCIe 2.0 connectivity to the motherboard and is the fastest SAS 2.0 RAID controller currently available on the market. The adaptive cache does cause some issues while testing since the technology is designed for real world performance increases and is way ahead of current benchmarking software.
What it boils down to is that adaptive cache actually makes real world tasks faster than what they appear in our snapshot style benchmark software that was designed to record performance under the old way of doing things.
ATTO Baseline Performance
Version and / or Patch Used: 2.34
ATTO is used by many disk manufacturers to determine the read and write speeds that will be presented to customers.
In ATTO we see data transfer rates exceeding 730MB/s with the combination of hardware used. In the 16k test we actually saw a massive 856MB/s read.
