Nevertheless, OCZ claims that new firmware update v1.13 significantly improves Random Write 4K IOPS performance across the board. The 128GB model can expect a 134-percent net performance improvement over previous firmware, the 256GB version can expect a 108-percent net improvement, and the 512GB model can expect a 63-percent net improvement.
As a rule of thumb, the smaller capacity drives will see the bigger improvements. As AnandTech notes, however, the performance of these Indilinx controllers are still nowhere near those of SandForce-based SSDs or the Crucial m4. We expect OCZ is aggressively working to alleviate the performance gap among its competitors and should be able to fill the gap more closely in its next-generation controller architectures.
