Most IO graphs would be better reported as MB/s and provide table to display results. The graphs you have are only about 10% useable. IOps are only of interest at the extremes of max throughput, max IOps and min IOps across all block sizes (not per block).

Sometimes several graphs from IOmeter become redundant when they are highly correlated (same result presented three different ways eg. IOps, MB/s, ms/IO).

FLASH based SSD require more/expensive components to reach higher sequential and random read and especially write performance. FLASH based SSD are not as good as they could be.

Is there anything like comparable to iram that will handle 8 or 16gb?

That would be so good for premier scratch disks or stream audio samples for a live PA.

there is an I-ram 2.0, its sata2.0 and uses ddr2 memory and is installed as a bay-device, like a cd-rom drive, just look at ebay
