No it's just different versions of the controller , as long as it is in the 2200 model version then you can expect the same or close to the same performance. If the 2200 has slower speeds it will be small. In some cases the speeds on the 2200 controller are actually faster than the 2281. Like in the two SSD's that are listed below , the Corsair with a 2200 controller has faster read/writes than the OCZ SSD that has the 2281 controller.
The 2200 does not refer to a specific SandForce Controller. The 2200 is a series designation. There are several different models in the 2200 series. Some models are designed for enterprise use while other models are designed for consumer use. The most common model is the SandForce SF-2281. There are variations of that model also. For example, The Intel 520 ssd uses the SandForce SF-2281VB1-SDC.
Here is a link to the ssd database that is referenced in the sticky at the very top of this forum section:
As you scroll down you may still see SandForce 2000 listed in a few spots. I did it because the initial press releases did not fully identify the controller. In addition the manufacturers do not always fully identify the controller on their product pages. The best source of information are the technical reviews. For most reviews the ssd's are actually opened so that the reviewer can correctly identify the NAND, the controller, and other components.
Thanks to your post I noticed that additional information is available for some of the ssd's. I will update controller information tomorrow.
inzone - According to technical reviews and visual inspections both ssd's you referenced use a SandForce SF-2281 controller.
I went through the ssd database this morning and updated as many SandForce controllers as possible that had been listed simply as 1200, 1500, 2000, and 2200. There are still a few ssd's for which the information is not available.
In the meantime, CEBIT 2012 is taking place in Hannover, Germany. There have been quite a few announcements for new solid state drives, including some new players. Looks like I'll have to do a major update this coming weekend.
