ADATA Premier Pro SP920SS 256GB uses a Marvel 88SS9189 controller, the same controller that is used in Crucial M550. This controller adds LPDDR (or low-power DDR) and improved DevSleep implementation. In fact, if you’re familiar with Crucial M550’s PCB layout, it’s no different from this drive.

What’s different is the SSD uses eight chips of 20nm 32GB Micron MLC 128Gbit NAND chips. Crucial uses 128Gbit NAND for its 512GB and 1TB units, whereas they use 64Gbit NAND for lower capacity 128GB and 256GB unit. I haven’t tested Crucial units so it would difficult for me to say how the performance differs in benchmarks and tests. But Micron’ 128Gbit NAND cost lesser therefore helps to bring 256GB units as the new mainstream choice for users who require faster load for everyday computing requirements.

What I can say is how this drive performs in comparison with other drives…
