Patriot Zephyr 128GB Review

The JMicron JM602 controller, paired with insufficient cache, hobbled the first generation of consumer SSDs—once the cache filled, write speeds slowed to a crawl. Random-write latencies could get as bad as a fifth of a second (compared to .1ms for most modern SSDs), pulling average sustained writes down as low as 20MB/s in some cases. Manufacturers responded by adding more cache or by building future generations of drives on different controllers, such as the Barefoot Indilinx part. Since then, JMicron has been pretty quiet, but now Patriot’s Zephyr line has arrived, powered by JMicron’s new JMF612 SATA controller.

At the time, we wondered why OCZ would artificially limit supplies of an SSD with such great performance. And now we know: It was a trial run to help SandForce, a recent startup, gain capital to scale up production. It’s since done that, and in gratitude to OCZ has granted the company exclusive random-write-IOPS-boosting firmware for its Vertex 2 drives. The new firmware will be available to other SF-1200 drives (probably by the time this issue hits stands)—but as of press time, it’s an OCZ Vertex 2 exclusive deal. Ethics of “exclusive firmware” aside, is the Vertex 2 any better than its Limited Edition stable mate?
