Internals, Testing Methodology and System Setup

Internals:

With no assembly screws to speak of, disassembly requires the use of a spudger.

Once disassembled, we find that Samsung has reduced the PCB to a 1.8" form factor.

This gives the added benefit of a bit of future proofing for those who may want to shift

the SSD over to a small(er) form factor netbook somewhere down the road.


PCB front reveals the controller, half of the DDR cache, and 7 of the 16 flash chips.

The black rounds out the other half of the DDR and the remaining 9 flash chips.

The 470's (right) older brother, the PB22-J (left), was larger, and had a 6/10 front/back split of flash parts.

Testing Methods  


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 have switched our testbed over to a more dedicated, forward thinking machine.  We made some changes to help minimize test data scatter with higher bandwidth devices.  Sound is flat out disabled, with no additional card installed.  Video was *intentionally* shifted to a PCI unit to free up both PCIe-16 slots for testing tandem pairs of PCI Express cards (like ioDrivesDDRdrives, and high end RAID cards).  Spot checks against the previous rig showed a negligible change in test output.      

PC Perspective would like to thank ASUS, Corsair, and BFG for supplying some of the components of our test rig.
