ADATA Premier Pro SP920 1TB SSD
The SP920 package is a carryover from years past and very close to the SP900 we reviewed a few years ago. This is ADATA's first 1TB capacity size SSD, though.
Inside, we found a quick start guide, instructions for Acronis, a 7mm to 9.5mm adapter, a desktop adapter bracket, and screws for mounting the drive to the adapter.
Here we get our first look at the drive. This is a new case design for ADATA but nearly identical to the case Crucial used on the M550. The top cover is a thin sliver of aluminum, but the rest of the case has some heft to it since it also doubles as a heat sink for the Marvell controller.
The SP920 is a 7mm z-height drive, so it will fit in your ultra-thin Ultrabook.
We're not sure if Marvell released a reference design and both ADATA and Crucial followed it to the letter or if both the SP920 and M550 are related in some way. Looking at both PCBs together, we only found one difference; the ADATA SP920 has one extra capacitor in the power management area of the PCB, but both drives use identical PCBs.
The Marvell 88SS9189 controller has a built-in thermal throttle. If the drive gets hot, it will reduce the speed of the controller to keep from malfunctioning. To help keep the controller cool, the case also doubles as a heat sink for the controller.
ADATA used Micron 20nm flash with 128Gb die and Micron DRAM for the page map buffer.
The SP920 has host power loss protection, but we haven't tested it yet in DriveMaster. Over the next few weeks, we plan to test this feature on the ADATA SP920, Crucial M550, and Intel 730.
