The 4K random-write speed is the lowest we've seen from an SSD. Clearly the JMicron 602 isn't so hot here. The good news is that, whilst the performance is low, we didn't notice any of the frequently-observed stuttering that's plagued previous JMicron-based solid-state drives.

Latency, too, is poor. It's difficult to notice in a single-user environment, but the performance delta would be noticed if you're into heavy, heavy multitasking.
