JMicron Returns: The JMF667H Controller On Four Reference SSDs
Features

It's rare that we get the chance to test SSDs before they hit production. But after waltzing with Silicon Motion's SM2246EN platform last year, JMicron offered us a handful of reference drives with different types of flash, all driven by the new JMF667H.
How We Tested JMicron's Reference SSDs
Our consumer storage test bench is based on Intel's Z77 Platform Controller Hub paired with an Intel Core i5-2400 CPU. Intel's 6- and 7-series chipsets are virtually identical from a storage perspective. We're standardizing on older RST 10.6.1002 drivers for the foreseeable future.
Updates to the RST driver package occasionally result in subtle performance changes. They can also lead to some truly profound variance in scores and results as well, depending on the revision. Some versions flush writes more or less frequently. Others work better in RAID situations. Builds 11.2 and newer support TRIM in RAID as well. Regardless, results obtained with one revision may or may not be comparable to results obtained with another, so sticking with one version across all testing is mandatory.
