Internals, Testing Methodology and System Setup
The Octane shares a housing with the Agility 3. The top cover portion is made of plastic. This is not necessarily a bad thing – many other manufacturers choose entire housings made of plastic, so long as heat production is not an issue.
The interesting bits hide on the bottom of the PCB.
…and the rest on the flip side. Note the extra SDRAM chip.
The shiney new Indilinx controller is paired with 512MB of SYNC DDR3 SDRAM, half of which is pictured here.
Storage is accomplished via IMFT 25nm flash, configured to run SYNC for the Octane.
We were a bit puzzled by the inclusion of what appears to be 8 4-bit 1-2 mux/demux chips from Texas Instruments. This configuration suggests this Everest is configured to run in 4-channel mode (8x 4-bit chips add up to split 4x 8-bit channels into a pair of the same, making up 8 channels). The question is – why add all of these extra parts when Everest is supposed to natively interleave multiple flash chips per channel? We don’t have that answer, but these are extremely fast multiplexer chips that are likely just as fast as the controller could have switched natively anyway. Hopefully the added complexity and chip count won’t negatively impact pricing.
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.
