Inside The Corsair Force GS

Corsair's Force GS uses a similar red plastic chassis as the Force GT.

Included in the retail bundle are two sets of mounting screws and a 2.5" to 3.5" adapter.

The actual PCB is a bit different from what we normally find inside 2.5" SSDs. Its length is only about four fifths of the backplane and it's held in tact by three screws (two in the corners, one in the middle) instead of four. I'm guessing the smaller PCB is slightly cheaper than a regular size 2.5" PCB would have been, hence Corsair opted for one. I don't really see any other explanation because the chassis is still normal size and weight benefit is marginal.

As for the components, there are eight SanDisk's 24nm Toggle-Mode MLC NAND packages on this side of the PCB. These are 16GB packages, meaning that each package consists of two 8GB dies.

Remove the backplane and flip the PCB around and we find another eight NAND packages and SandForce's SF-2281 controller.

Corsair isn't using thermal pads, which isn't all that suprising. Typically thermal pads are only found in high-end SSDs while lower-end models come without in order to offer more competitive pricing.

    One question, all of the tests at Anandtech for Sandforce performance after being hammered for a period of time are always over the entire drive. Do the drives maintain their performance if the random writes are only over 50% or 75% of the LBA's on the drive? Very few people actually fill up their SSD so I wonder if it is a truely relevant test?

    You will always eventually use all of your SSD, wear leveling algorithms will spread data across all NAND packages... A certain portion will always be marked "empty" if you haven't filled it to capacity, but that space has been issued and it's subject to the performance degradation conditions AT tests for.

    Time for an article on Cache Analysis?

    It looks to me as though the 1GB Dram Cache on the Intel DC S3700 is mainly responsible for smoothing out those peaks and valleys to deliver "Consistant" performance across the drive

    As for trim.....

    It's time to start with a fresh perspective on SSD's

    I know Intel claimed otherwise on the dram usage, but I don't buy it

    Sounds more likely they are just sending the competition on a wild goose chase

    Reread DC S3700 review again

    256MB of the 1GB is used for cache

    OK, my bad

    Doh

    If I read it 5 more times I'll get it right eventually

    If it were that easy, don't you think other guys would have drives like the 3700 out?

    The problem with caching in general is that there is no good way to test how much write/read caching the drive is doing. All we got is what manufacturers tell us, which may or may not be accurate.

    With each review, Samsung 840Pro looks better and better.

    This information has been already hashed over by several sites, in particular TweakTown. They have been educating the public for months about the lack of TRIM with Sandforce SSDs.
    Other sites have also noticed the read degradation, and commented on it ad nauseum.
