We knew the SandForce SF-1200 would live on for a long time after testing three or four drives in 2010. Even if SandForce discontinued the controller chip when releasing its successor, people would still be looking for drives based on SF-1200 since it is the best SATA 3G controller ever built. The SF-1200 is the Intel BX chipset for solid state drives and we will still be talking about it three years from now.
The Silicon Power V20 offers the same SandForce SF-1200 performance that we fell in love with in 2010. Other companies are going to keep SF-1200 offerings, but few will offer 34nm drives. Those with 25nm are still very fast, but not nearly as fast as those with 34nm. If I needed to buy a SATA 3G drive today it would be one with a SF-1200 and 34nm flash.
At the time of writing the Silicon Power V20 drives were not available at Amazon, so we don't have a final tally on the pricing. All we really know in this area for the 120GB drive is a rough estimate, around 200 USD. At that price, the Silicon Power V20 120GB is on par with many other SF-1200 offerings from other companies. To add to the final value, Silicon Power includes a desktop adapter bracket with the screws needed for installation and a 3 year warranty. The warranty is in line with several other manufacturers.
If you are not ready to invest in a new processor, motherboard (with SATA 6G) and all of the other parts needed to build a new system, then adding a low cost, high speed SSD is a great way to increase performance and user experience. If that sounds like you and you are not already on the SandForce bus, then the Silicon Power V20 is a really good way to make the journey to a really good user experience.
