SMART CloudSpeed 1000E Internals
The SMART CloudSpeed 1000E comes in a 7.5mm z-height metal casing. The 2.5-inch 7.5mm form factor is well suited for slim applications.
The case comes apart easily once four screws are removed. The thermal pad actually sets flush with the PCB on the opposite side of the controller, wicking heat away from the rear through the BGA mounting.
The rear of the PCB holds eight of the BGA-mounted 32GB NAND packages. The Toshiba NAND is actually jointly manufactured with SanDisk through their Flash Forward venture.
Power loss protection comes in the form of five capacitors on the bottom edge of the PCB, and an additional 15 emplacements on the rear of the PCB. This provides the SSD with enough power hold-up to flush data to the lower NAND pages. There are two DRAM packages, for a total of 512MB, above the Marvell controller.
The CloudSpeed 1000 marks a switch from the LSI SandForce controller with the CloudSpeed 500 to the Marvell 88SS9187-BLD2. This key step allows more flexibility for firmware customization, an important consideration for deploying the custom SMART firmware that allows the Guardian Suite to provide a 5X improvement in endurance over client SSDs.
