ADATA Premier Pro SP920 512GB SSD Review

ADATA carried over the retail package from previous SSDs but updated the text to reflect the new SP920's specifications.






Inside, we found a desktop adapter bracket, 7mm to 9.5mm adapter, mounting screws, a quick start manual, and a reminder to download the free software for data migration.




Here we get our first look at the drive. The top cover is just a thin sliver of metal for keeping the drive secure.




The bottom of the case is beefier and doubles as a heat sink for the Marvell controller and DRAM buffer.








ADATA used the new Marvell 88SS9189-BLD2 controller that's 8 channels to the NAND flash.




This controller has a higher clock speed than the 88SS9187 that Crucial used on the M500. It also incorporates a thermal protection mode, mainly for Ultrabook designs where the components are packed very close together. To aid in dissipating heat, the case acts as a heat sink.




There are sixteen NAND packages in total with eight on each side.




The SP920 also has host power fail protection, so if the drive detects a power fail event, it will flush the data in the controller to the flash even after the power falls away.




The Micron DRAM buffer chip. This model only uses one DRAM package, but the 1TB model uses two.




The NAND flash is Micron 20nm L85A.
