JMicron, the "star" of the first consumer SSD, is not dead. If JMF602 is infamous for its random write performance very low, which brought the "freezes" the machine from users, and JMF612 JMF616 have been used by some manufacturers - like Kingston - without making waves. And for good reason: Controllers, without being bad, are not the thunders of war.
For 2011 and 2012, the company will offer new controllers, JMF605, JMF606, JMF66x and JMF62x, chip a bit special. The controller is JMF605 entry-compatible SATA 3 Gbit / s and with 4 channels for memory. The expected rates are 160 Mb / s read and 130 MB / s write. The JMF606, its evolution is expected in 2012: still 4 channels, but with a SATA 6 Gbit / s.
The expected rates are 260 Mb / s read and 160MB / s write, with 10,000 IOPS write. This entry model range will be somewhat below the top models of 2011. The JMF66x, meanwhile, is a model "high end" SATA 6 Gbit / s, 8 channels, 500 MB / s read and 400MB / s write. Somewhat surprisingly, the company does not advertise the IOPS performance ...
Finally, the JMF62x is a chip for hybrid storage devices. While Intel has a software solution with the Z68, JMicron will use a hardware solution, like Marvell. The principle is simple: a SSD (4 channels) fits between the drive and the SATA controller and serves as a cache. JMicron Announces 70% performance of a conventional SSD, which seems rather pessimistic about what Intel and Marvell promise.
