A closer look at the Corsair Neutron GTX hardware.
Let’s take a look at the hardware found inside the Corsair
Neutron GTX SSD.
Inside the case.
Inside the case of the SSD we can see that the printed
circuit board doesn’t run the full length of the case.
On the top side of the PCB we can see that the component
count is quite low. We can see the first of two 128MB of DDR2 800 cache. It is
understood that the cache on the Neutron GTX is not used for caching data, so
the most likely use of the cache is to hold the FTL and LBA tables.
On the underside of the PCB we can see eight NAND chips
manufactured by Toshiba, the second 128MB of DDR2 800 cache, and finally the
LAMD LM87800 SSD processor.

Above we can see the LAMD LM87800 SSD processor. The LM87800
is a dual core device, most likely an ARM 9. There isn’t a lot known about this
processor, but it has 8 channels to the NAND array, and NAND endurance is
handled by a technology known as EBoost.
Toshiba toggle mode MLC NAND
The NAND onboard the Corsair Neutron GTX is Toshiba toggle
mode, with each NAND package having a capacity of 32GB giving a total of 256GB
of NAND flash memory. Corsair have 13% of the NAND set aside as an
over-provisioned area. When the Neutron GTX is formatted, the user is left with
Although 128/256bit AES encryption is supported in hardware,
Corsair have not implemented AES encryption in the Neutron GTX.
Drive maintenance features
For Windows 7 users and some distributions of Linux, the Corsair
Neutron GTX SSD supports ATA TRIM to keep the NAND clean. The Corsair Neutron
GTX also has advanced garbage collection to clean the NAND during drive idle

testing methods and the review PC.
