Corsair Force GT SATA III 120GB SSD Review

Inside the Force 3 GT

Four Phillips head screws and two warranty voiding sticker breaks later,
we cracked open the case to see the components on the Force 3 GT 120 GB
SSD.

As usual, one side of the PCB features two rows of four (or vice-versa) NAND chips and little else.

A closer look at the MLC NAND yields part number 29F64G08CBAAB which are 25nm Micron synchronous modules. These are faster and more expensive than the synchronous NAND found in the original Force 3 drives. Each are 8 GB in capacity for a total of 128 GB across all sixteen modules.

On the flip side is the remaining NAND chips along with the controller sitting adjacent to the SATA connectors.

The SandForce SF-2281 controller is the heart and soul of the drive, handling all of the important duties such as wear-leveling, real-time compression, encryption, and most importantly error correction. With the 25nm NAND, errors are much more common and must be addressed appropriately. It’s proprietary DuraClass technology is primarily responsible for most of these tasks and we’ve seen that it’s very adept at its job. Add to all of that TRIM and garbage collection support and you have a drive that will maintain a high level of performance for extended periods of time.
