Let's knock the OEM / ODM thing out first. There are several companies that are selling the Samsung drive, including Samsung. This is common in the computer hardware world and easy to sort out for the end user and hardware reviewer. Basically, what the end user will want to do is, if the product is deserving, purchase the one that has the lowest cost and the longest warranty. Luckily the G.Skill variant has the lowest cost when compared to the Samsung and OCZ drives and by a large amount.
When it comes to performance the G.Skill SLC based drive is the benchmark in which all others should be compared. The drive is fast in all of our benchmarks, a task that is not exactly easy to do, as we proved in the Crucial SLC review. It isn't going to matter if you are running a large database or installing this drive in your notebook, the drive is simply fast and everything you run off of it will benefit from faster load times and overall "snappiness".
The only real downfall is in the price. Just as SSDs are guaranteed to have very low access times, they are also guaranteed to cost more per Gigabyte them their platter based competitors. To extend that, the SLC drives cost a great deal more than the MLC drives but offer a longer lifespan and in most cases faster performance.
