We've looked at the Corsair Performance 3 in both 256GB and 128GB sizes and in both cases found that the new Marvell 88SS9174-BKK2 controller offers the best garbage collection system we've ever seen. On the surface garbage collection may appear as a throwback technology only needed in SSDs running on Windows XP / Vista or MAC Oss, since Windows 7 takes advantage of TRIM commands.
The reality is that Windows 7's TRIM works pretty good on single drives running the right drivers, on the right controllers under the right conditions, but enthusiasts and power users who run RAID arrays still do not have TRIM. When TRIM is not present an SSD or arrays of SSDs slow over time since the drive needs to erase prior to writing data to a block of data. The Corsair Performance 3 with its advanced garbage collection is able to keep data situated in a way that keeps the drive running at full speed all of the time.
