A huge part of this SSD performance leap was thanks to Indilinx and Samsung drive controller chips in 2009 - With much larger cache memory than any of the JMicron based SSD's that dominated the beginning of the year - these two new SSD controllers took Read (and more importantly) Write performance to new levels exceeding well over 200Mbps.
It also led to a leveling of the playing field: As most current solid state drives now use these controller chips - performance has largely evened out. So whether it's an SSD from OCZ, SuperTalent, Patriot or others - the guts inside are largely the same with more minor variations in cache size and speed of NAND flash used. Data transfer rates are far more incremental now - not the huge leap we saw earlier in the year.
The best value lies in these few drives: An OCZ Agility
