Internals, Testing Methodology and System Setup


First a look at the front and rear:

Now let us crack open the screwless housing:

No screws present at all, yet the fit and finish is solid and once assembled there are no noticeable rattles. Nice work for a budget product.

At the front we have a Marvell 88SS1074 controller, which implements LDPC and supports the installed TLC flash. We also get some DRAM and four Micron-branded flash packages containing two 384 Gbit (in TLC mode) / 48GB IMFT 3D NAND dies.

Sitting between the controller and flash we find a bank of capacitors. These help provide power loss protection. If system power goes away for any reason, the capacitors should provide enough juice to keep everything powered long enough for a graceful shutdown of the SSD itself. This helps prevent corruption of the Flash Translation Layer – something that can result in data loss or in extreme cases 'bricking' of an SSD.

At the rear we have four more packages, rounding out the full 750GB capacity.

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. 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 an ASUS Z87-PRO. Variance between both boards has been deemed negligible when testing SATA devices. Future PCIe and SATA device testing, including this review, take place on a new ASUS Sabertooth X99, which comes equipped with USB 3.1, M.2, and can also handle SFF-8639 devices with the proper adapter.

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