Corsair P128, 128GB: CMFSSD-128GBG2D
Corsair, the well-known maker of high-performance RAM, USB flash drives and power supplies, has taken to SSDs very seriously. The company now offers as many as three SSD series: Legacy, Performance and Extreme. Interestingly, these three series are all based on MLC memory chips. The Legacy series includes early SSDs from Corsair which are based on somewhat outdated controllers (this is how quickly things change in the industry: multi-channel controllers came out just a couple of years ago, but now there are already outdated models in the product range). The company doesn’t make a secret of the differences between the other two series. The Performance line includes models with capacities of 64, 128 and 256 gigabytes based on a Samsung controller. The Extreme series is based on an Indilinx Barefoot controller and comes in smaller capacities: 32, 64 and 128 gigabytes. Corsair claims the former series to deliver stable performance and the latter, maximum performance.
So, we’ve got a Performance series sample. For each model in the series, the manufacturer declares sequential read and write speeds of 220MBps and 180MBps, respectively. The junior models do not have fewer channels. Instead, they just use smaller-capacity memory chips. The SSD does not differ from others of its kind externally. It is a standard box measuring exactly like a 2.5-inch HDD and having the same mounting holes. The four screws in the cap called to be unfastened, so we removed the cap (which is made of some aluminum alloy):
We can see a PCB with controller, RAM chip and 16 flash memory chips located on both sides of the PCB. The controller is Samsung S3C29RBB01-YK40 also known as PB22-J. It is the latest generation controller which is used in modern SSDs from Samsung and some other brands. The other chips are manufactured by Samsung, too. These are the 128MB SDRAM chip Samsung K4X1G323PD-8GC6 clocked at 166MHz and 16 NAND MLC chips K9HCGZ8U5M from this series. Quite expectedly, Corsair did not develop its own SSD design but used a partner offer in the way of a ready-made Samsung SSD.
