The housing and assembly is of good quality materials, and the aluminum doubles as a heatsink for both the Marvell controller and RAM.

The PCB design is slightly different from the ADATA models, but they contain the same 8x Micron branded Synchronous MLC flash packages. This was the case for all four SSD capacity points, meaning capacity scaling is accomplished by die counts within the 8 packages, and ensuring the controller always communicates over 8 physical channels.

PCB rear is mostly blank, and again was the case for all four capacity points.

Testing Methodology

Our tests are a 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 currently employ a pair of testbeds. A newer ASUS P8Z77-V Pro/Thunderbolt and an ASUS Z87-PRO. Variance between both boards has been deemed negligible.

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

You were all impressed with performance vs price for these 550 SSDs greater than 128Gb, and I tend to agree. The Samsung EVOs seem to be an additional $20-30, but the Samsung Magician software especially for firmware update notification is excellent. Does Crucial have software similar to Magician ? Because firmware updates are a pain.
