SATA 2 Performance
<i>In a perfect world everyone investing in a new solid state drive would have access to a SATA 6GB/s controller which could pass on the TRIM command. In reality not everyone has this and for many the decision comes down either giving up TRIM – never a good idea with most controllers – and running it off a secondary controller; or taking a performance hit and running in SATA 2.0 mode.
These tests will consist of some of our real world and synthetic benchmarks run on our standard 1155 test-bed; but the drive will be attached to an SATA 2 port.
For synthetic we have opted for the newcomer to our charts: Anvil Storage Utilities Pro. For real world we have opted for our Adobe test. These two tests should give you a very good idea of the level of performance impact you can expect from running a modern SATA 6 drive in compatibility mode.</i>

Using any SATA 6Gb/s drive in SATA 3Gb/s already impacts performance, but it seems the ARC 100 256GB is hobbled at certain read queue depths due to either firmware immaturity, controller limitations or some other reason.
