The Intel 510 is a fairly stable and reliable solid state drive. Early this year when solid state drives equipped with SandForce controllers developed major issues, the 510 was viewed as an excellent alterantive. The only problem was gamers and enthusiasts did not like the 510's synthetic benchmarks. On the other hand web sites like AnandTech and other review sites recommended the 510. The synthetic benchmarks don't always reflect real world performance. Then an issue developed related to sudden power outages. Intel issued a firmware update to solve the problem.
The Intel 520 series is the successor to the 510. Originally it was thought the new ssd's would be released last month. That did not happen. Some sites like The SSD Review recently published articles indicating the release was imminent. Other sites published articles indicating Intel delayed release until the first quarter of 2012. There is quite a bit of speculation and unsubstantiated rumor that the new 520 would use a SandForce controller. Intel has remained silent about the matter.
In the meantime, Samsung staged a major coup. Samsung was awarded contracts to supply Dell, Sony, Lenovo, Apple and other off the shelf brands with OEM versions of their 470 Series SATA 2 3Gb/s ssd's. Eventually the 470's were released for retail sale to consumers. There have been no major issues reported. The 470 has an absolutely stellar record.
Recently Samsung released their new 830 Series SATA 3 6Gb/s ssd's. The first ones were OEM versions for Dell and the other off the shelf brands followed by release of retail versions for consumers. Although the ssd has only been available to consumers for a few months it looks like Samsung got it right again.
The Corsair Force 3 ssd's use the same Sandforce 2281 controller that is inside the ADATA S511, OCZ Agility 3, and Vertex 3 drives.
