Kingston SSDNow V (2nd Gen - JMicron JMF618) 128GB SSD Review
 

Kingston's 'V Series' of SSD's has gone through a few iterations over the past year. It started out with 64 and 128 GB JMicron 602B drives. After some time, a 40GB model was added, this time with a stripped down version of the Intel G2 controller. That model was shortly discontinued along with the rest of the line. All have been superseded by a new series carrying the same name. These new drives contain controller design which is a hybrid effort by JMicron and Toshiba. We'd been anxiously waiting for new JMicron silicon to materialize and today that wait finally over.


Our fears in the prior tests were confirmed with our IOMeter test suite. The competition climbs all over itself while the JMF612 stays horizontal, joining the OCZ Summit. A flat line in this test means the drive does not take advantage of Native Command Queueing (NCQ). NCQ is a means for the OS to pile several requests onto the drive simultaneously. Drives taking advantage of this can use it to parallelize it's internal communication with the flash and ultimately ramp up their speed even further. The JMicron controller may not have scaled well here, but at least it's cache doesn't get overloaded like the Samsung (Summit) does
