has released a new firmware for its P series solid state drives which gives them TRIM support. The P64, P128 and P256 are all based on Samsung controllers and offer read and write speeds of up to 220MB/s and 200MB/s (120MB/s for the P64) and have 128MB of cache.
The new firmware has been beta tested by Corsair and the update tool comes directly from Samsung. This is a good thing as Corsair certainly took its time to get this one out which means that the new firmware should at least be bug free.
The new firmware version as well as the update tool can be found over at Corsair's forum
