I finally found a good analysis of what's wrong with most of the cheap MLC
drives:

240ms random write latency...wow, no wonder I keep hearing so many reports
of cheap SSD just performing miserably.  JMicron is one of those companies
I really avoid, never seen a design from them that wasn't cheap junk.
