Right now we're still in a silly season with most of the SandForce drives. While everyone has the TRIM fixing code in the lab, very few are going to release it to the public as is. Just today we learned that 5.0.3 does not pass WHQL certification. We think this too has to do with TRIM, but that is pure speculation (with a little insight). We were told at CES that a TRIM operation is allowed just 70 ms to pass WHQL. We know SandForce and the manufacturers are scrambling to get everything worked out so the OEM system builders are happy. In our testing we proved that TRIM on the Force GS makes for a much nicer performing GS. It would be nice if Corsair releases 5.0.3 to the public, even if it comes with a warning about its beta status.
With that said we have another issue to tackle. We know that the SF-2281 / asynchronous flash Force 3 is the baseline model, but with the Force GS and the Force GT both performing so well, which do you buy? If the Force GT was like most of the other SF-2281 / synchronous flash drives that would be easy to answer, but the GT isn't like any other drive on the market. The Force GT, at least the 240GB uses a SF-2282 controller and pairs it with 32 IMFT 25nm synchronous flash chips. The 32 chip design is very fast, but until we get the same firmware for our Force GT, we can't say which model is faster.
When it comes to the price, the Force GS 240GB is around $20 cheaper than the Force GT 240GB at Newegg. We'd still like to see the side by side performance, but for many, the difference between the two would be trivial. The $20 price difference on the other hand is more substantial. Both drives ship with the same accessory package and three year warranty so neither drive has an advantage of there.
When comparing the Force GS to other existing drives on the market that use 24nm Toggle Flash, the Force GS has an advantage in the flash count. Most of the 240GB drives with 24nm Toggle use just eight NAND flash chips, but the GS uses 16. In most cases, but not always, the more flash on a drive the better, because you increase the interleaving.
If you're looking for a new solid state drive right now the Force GS is a solid choice, but the firmware upgrades in the future might turn a lot of people off. At this time, if you want the best performance in an SSD you have to consider a SandForce based model in the 240/256GB capacity size and that means you'll have to work a little to keep it running at peak performance at this time.
