When it comes to solid state drives the controller is the heart of the drive. There are SSDs on the market that are using bottom of the barrel, slow as molasses NAND flash, but their controller is able to make it all come together. Most of the time we are able to find out what controller is in a product and have a very good idea about the drives performance.

As it sits right now I have no idea what controller is in the Western Digital SiliconEdge Blue. To further aid to the confusion the cache is larger than anything we have tested before. The good thing is that when we buy SSDs we are rarely buying a name or the laser etches found on the controller. Pricing, performance, overall value between the two, length of warranty and a company’s reputation on standing behind their products is what we are breaking our wallets out for.
