OCZ keeps releasing new SSD series. After the Vertex series, originally launched as a mid-range product, and now so popular that it ranks as high-end models, OCZ introduced the Agility series.
This new mid-range product is based on Indilinx Barefoot controller associated with 64 MB of cache, however performance will be lower than with the Vertex:
The 30 GB model should offer 185 MB/s and 100 MB/s respectively in reading and writing mode.
the 60 GB and 120 GB models will have higher performance with respectively 230 MB/s and 135 MB/s in reading and writing mode.
This is mostly the performance level of the writing speed that is slower wit the Agility series than with the Vertex series, this might be linked to the way OCZ designed the PCB and the bandwidth. Prices remain unknown, however, they should be lower than the Vertex
