SATA 2 Performance
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.
Although the performance of the V300 does suffer from being used in SAT 3Gb/s mode, these numbers are still quite reasonable. It appears that the 19nm NAND and custom firmware does help the aging SF2281 controller better cope with being run in compatibility mode.
