Internals, Testing Methodology and System Setup






Controller close-up:

Chip counts and analysis:

  • 1x   SM2258 Silicon Motion SSD Controller
  • 2x   D9SHD / MT41K256M16TW-107:P 512MB DDR3L SDRAM (total 1GB)
  • 16x NW925 / MT29F512G08EECAGJ4-5M :A 64 Layer 3D NAND Flash
    • Each package contains 2x 256Gbit (32GB) dies

Overall fairly straightforward for a SATA SSD layout, though we're used to seeing fewer chip counts at an equivalent capacity. Micron says an M.2 form factor is coming, so it will be curious to see how they manage to stack and arrange these dies within an M.2 2280 form factor.

Testing Methodology

Our tests are a mix of synthetic and real-world benchmarks. IOMeter, HDTach, HDTune, Yapt and our custom File Copy test round out the selection to cover just about all bases. We have developed a custom test suite as off-the-shelf tests just no longer cut it for in-depth storage testing. More details on the next page. 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 several storage testbeds. A newer ASUS P8Z77-V Pro/Thunderbolt and a Gigabyte Z170X SOC Force (for RAID testing). Future PCIe and SATA device testing, including this review, take place on an ASUS Sabertooth X99, which comes equipped with USB 3.1, M.2, and can also handle SFF-8639 (U.2) devices with the proper adapter.

PC Perspective would like to thank Intel, ASUS, Gigabyte, Corsair, Kingston, and EVGA for supplying some of the components of our test rigs.
