The Marvell based drives from 2011 were very good products, they just had a very big umbrella over their head. Pricing always plays a large role in the retail purchasing decision, especially in a slow moving economy. The Marvell controlled products are at a disadvantage when it comes to price out of the gate. The architecture calls for a DRAM cache buffer, an added expense, when compared to the SandForce design that runs an internal buffer in the controller. When you add the additional cost with the lower performance compared to many of the SF-2281 controlled drives, there just wasn't enough incentive for consumers to come home with a solid state drive using a Marvell controller.
The 2012 SSD season is now in full swing and unlike last year, SandForce doesn't have a new controller ready to follow their successes of the last two years. Furthermore, the Team SandForce partners are tip toeing into 2012, we've yet to see an established Team SandForce member show a drive with the latest generation flash coming from Samsung and Toshiba. SandForce is leaving a door open and in this competitive market others are rushing to get their foot in the door.
