Internals, Testing Methodology and System Setup
Well, there really are no internals to a PCIe SSD, so here are some close-ups:
One of 4 SandForce controllers, coupled with IMFT 25nm flash memory.
The VCA 2.0 controller (above) and some extra energy storage in the form of a bank of capacitors near an inductive filter (below).
More controllers and flash.
Edge-on, we see flash installed on both sides of both boards.
LED status lights let you know which controller channels are active.
Our tests are a good mix of synthetic and real-world benchmarks. PCMark, IOMeter, HDTach, HDTune, Yapt and our custom File Copy test round out the selection to cover just about all bases. If you have any questions about our tests just drop into the Storage Forum and we’ll help you out!
Test System Setup
We’re breaking in a new SandyBridge testbed. Necessary for properly testing these new drives, even with the known issues. To get around this, we are using only the Intel SATA 6Gb/sec ports, which are known to not exhibit the inconsistent performance / connectivity issues.
PC Perspective would like to thank ASUS, Corsair, and Kingston for supplying some of the components of our test rig.
