Internals, Testing Methodology and System Setup


Digging into these was quite easy. No screws to get the lid open. Thermal pads help conduct heat to the lid.

Further disassembly revealed additional thermal compound that appears to be doing the bulk of the cooling here.

Starting with the 1,920GB ECO model, we find the very capable Marvell 88SS1074-BSW2 controller paired with 1GB of DDR3.

On the flip side we find another GB of DDR3. Flash loadout comes to 10x four-die-packages and 2x two-die-packages. Total NAND comes to 2,112GB on this 1,920GB part (10% OP).

Skipping straight to the 960GB MAX, we find the same controller, half the DRAM of the 1,920GB ECO model, and a different flash layout (4x four-die-packages and 8x two-die-packages). That's 1,536GB of flash on this 960GB SSD (60% OP)!

*NOTE* In case you missed it earlier, these are pure TLC SSDs. No SLC cache, no MLC anywhere. Nothing but Micron's 3D eTLC (384 Gbit per die).

Testing Methodology

This is our first review using a purpose-built enterprise testing suite. We will cover the methodology further into the review and welcome your feedback on our process and presentation.

Test System Setup

We have several storage testbeds, but for this piece we used the same setup used in our 5-way SSD 750 RAID testing. It is not true server-class hardware, but it is a reasonable equivalent that allows us to push the CPU to higher clock speeds than server hardware would normally be capable of. This helps shift the burden / bottlenecks to the SSDs being tested.

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