Anand's test of GC recovery is not very realistic. He uses HD Tach to do a 100+ GB sequential write to the SSD and looks at how the write speed degrades during that humongous write. Not many people do that to their SSDs. Also, he does the same thing to Sandforce SSDs, which is absurd, since HD Tach writes zeros, and Sandforce ends up writing almost nothing to the flash when you give it 100+ GB of zeros.

If you give the m4 a more realistic workload (for example, IOMeter with a reasonable mix), the GC works well.
