It is strange that ADATA have not protected thier product with a warranty seal however we feel there is no need for such a seal as there really is no need to take a peek inside as nothing can be modified to any useful extent that we are aware of.


The ADATA SP920 looks strikingly similar to the Crucial M550 both in layout and component choice right down to the last capacitor.


The PCB is made up of eight 20nm 32GB Micron Synchronous MLC NAND FLASH chips. 128Gbit NAND chips may work very well for high capacities but can often effect lower capacity drives due to the effect of having decreased NAND parallelism.


Controlling the drive is the Marvel 88SS9189 Controller. This controller and flash NAND are accompanied by Micron DRAM Cache. Both the Cache and Controller receive cooling via a thermal pad.
