Computex 2014 SanDisk had the massive 4TB Optimus MAX SSD on display in their booth today, and we just had to take a look inside. The SanDisk Optimus still holds the performance crown for 6Gb/s SAS SSDs on the market, and the expansion to 4TB of capacity provides even more density.
Cramming 4TB of NAND goodness into a 2.5" 15mm form factor requires the use of several PCBs. SanDisk utilizes a ribbon-type connection between three PCBs, which then fold into each other to fit inside the chassis. SanDisk employs the same Marvell controller as previous Optimus SSDs, but the real secret sauce lies in their custom firmware, which enables Guardian Technology, a full suite of flash enhancements that extends NAND longevity.
The Optimus MAX uses a familiar 6Gb/s dual-port SAS connection, which allows speeds of up to 1 GB/s from one SSD.
The rear of the PCBs holds more NAND, and we also spot a few more Tantalum capacitors on the rear, which provides power hold up in the event of power loss. We inquired about any possible heat impact from so much NAND placed in such a small package, but are assured the Optimus MAX functions as any normal SSD, and doesnt require any extra airflow or special considerations.
The acquisition of SMART by SanDisk has proven to be a home-run already, and they are just getting started. The SanDisk NAND, pictured here, is the culmination of 26 years of design and innovation in NAND technology. Keep your eyes peeled for a full product evaluation of the Optimus MAX here at TweakTown.
