Storage/SSD by stefan @ 2012-10-15
The Vertex 4 SSD from OCZ no longer uses a SandForce processor, but an Indilinx Everest 2 one, meaning that we do not longer have a lot of space used for over-provisioning and we should not have performance drops when using incompressible data. OCZ have also fine-tuned the firmware so performance delivery is different after the drive has been filled over 50% of it's total storage capacity.

The OCZ Vertex 4 128GB SSD comes unformatted out of the box:
After the SSD has been formated NTFS, here is the total free space reported by Windows 7:
With the help of AIDA64, we can extract more information regarding the drive:
Since firmware 1.4, OCZ has optimized the firmware for the Vertex 4, so the SSD behaves differently depending on how much space is filled on the drive. If the drive is half-full, we will enjoy optimized performance and after crossing more than half full, the garbage collection algorithm will re-optimize the drive for maximum efficiency based on a larger data footprint. Because of this, we will test the drive in two modes: empty and filled over 50%.
