7-Way SSD Round-Up: Sandforce vs. JMicron
Patriot Zephyr
Patriot Memory recently releaed the Zephyr line of Solid State Drives, based on the JMicron JMF612 controller. Unlike the other drives featured here, the Zephyr's capacity is somewhat larger at 128GB, but the performance of the JMicron controller isn't on the same level as the SandForce SF1200...

The JMicron based Patriot Zephyr 128GB drive's specifications show max read and write speeds that are significantly lower than those of the SandForce based drives (240/180MB/s versus 285/275MB/s). Also note, it is the only drive in the round-up to feature a DRAM cache. SandForce's controller is designed as such that it doesn't require external DRAM cache, but the JMF612 is a differnt animal, and hence, performs best with some cache attached. TRIM support is present here as well, and Patriot offeres a 3-year warranty on the device.
