4k random writes over 1MB/sec is extremely good as measured here:

You can see for yourself that 7200rpm SATA drives would struggle with that even on a Caching controller and 10,000rpm and 15,000rpm scsi/sas drives can manage 3MBps at those sizes.

If a Vertex can pull even 5MB/sec with those settings its nothing short of flat out amazing for that file size.
