Benchmark from 2008 comparing it to first generation 32GB and 64GB SSDs. That is beyond obsolete in computer years. That test was done on a Pentium 4 machine with XP. And you are confusing the interface on a mechanical drive being SATA 3 with the real world performance of a SSD being able to saturate that interface completely. There is already a new SATA standard planned because SSDs have reached the limit of SATA 3.
The article you linked to shows the iRAM losing to a 15,000 RPM server drive. Any modern SSD will destroy a 15,000RPM drive or any other mechanical drive. Even my 3 year old 120GB OCZ Vertex 2 is faster than any hard drive and it's practically an antique by SSD standards.
Look at sequential reads and writes.
iRAM gets about 120MB/s sequential read.
The slowest SSD on the Anandtech list gets 289.1MB/s
The fastest SSD gets 437.6MB/s
Sequential writes.
iRAM gets about 110MB/s
Slowest SSD 139.6MB/s
Fastest SSD 384.4MB/s

Just using your link and the link I provided to Anandtech will let you compare directly. Sequential reads and writes only tell a very small part of the story as you have to analyze queue depth and IOPS as well as the type of data, compressible or uncompressible. Trust me the iRAM is obsolete and about useless. There is a reason Gigabyte never made newer models of it.
