    OCZ has launched a new version of its 3"1/2 Colossus SSD, the Colossus LT. Still in 3"1/2 format, it has been announced in 120, 250, 500 GB and 1 TB versions and is still made up of a RAID 0 and two SSDs based on the Indilinx Barefoot controller. This RAID 0 is invisible to the system but it makes it impossible to use the TRIM feature on the Barefoots which fall back on their Garbage Collection algorithm to try and maintain performance levels at a max over the course of usage.


    In terms of performance, OCZ has announced up to 260 MB/s reads and 260 MB/s writes (220 MB/s continuous) and 15,000 IOPS for 4 KB random access. This is then not greatly different to the previous generation. So what is the difference between the Colossus and the Colossus LT? In fact, this new version uses smaller 34nm MLC and will be between 5 and 10% cheaper for equivalent capacities.
