That's horrifying. 4.9MB/s random writes? 19.7MB/s random reads? That's
at least an order of magnitude lower than other SSDs of that generation.
I can't imagine that would be very good for database usage patterns by
comparison. Especially with that aggressive garbage collection.
I mean... an old Indilinx OCZ Vertex has better performance than that.
