To be fair, we have yet to see a truly perfect SSD controller. Intel, Indilinx, Marvell and SandForce all had little issues that when ran across would drive you a bit crazy. When buying a SSD you want to look for the drive that best suits your needs and data usage scenarios. For the most part JMicron drives have only fit one category, low price.
The latest update to the long line of relatively unpopular controllers from JMicron is the new JMF616. The 616 uses twice the cache capacity found on the JMF612 and allows the controller to be used with the latest available Intel NAND flash. The ADATA S596 Turbo is the first SSD to use the new JMF616 controller and today we are going to give the drive a run through.
