OCZ Vertex Turbo, 250GB: OCZSSD2-1VTXT250G

 

 

Here is one more OCZ drive with the word Vertex in its name and based on the Indilinx controller. The distinguishing features of the Vertex Turbo are easy to see, though. Its memory and controller work at higher frequencies. This must be the reason for this controller to have only one firmware version, 1.0. We will see if the minor increase in frequencies (e.g. the memory frequency is overclocked from 166 to 180MHz) can affect the SSD’s performance or the multiple changes in the firmware of the ordinary OCZ Vertex have a bigger effect. The specified speeds are the same 270-210-120MBps at least.

OCZ Agility, 60GB: OCZSSD2-1AGT60G

 

 

The Agility is one more SSD from OCZ based on an Indilinx controller. OCZ refers to all Vertex series drives (irrespective of any suffix in the model name) as to performance products whereas the Agility series is referred to as mainstream. This SSD probably uses cheaper memory and fewer memory channels. The maximum storage capacity of the Agility series is 120GB and the specified speeds are lower than those of the same-capacity Vertex: 230-135-80GB. The firmware is version 1.3.

OCZ Summit, 120GB: ОСZSSD2-1SUM120G

 
 

The OCZ Summit drive comes from a performance series but is based on Samsung’s latest platform rather than on Indilinx’ controller. We know the platform by the Corsair P128 SSD as consisting of a Samsung S3C29RBB01 (PB22-J) chip together with 128 megabytes of cache. The specified read and write (both peak and sustained) speeds are 220MBps and 200MBps. The firmware version is VBM1801Q.
