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…

BBQ Score

Summary : The ADATA SP920SS 256GB doesn’t really bring any special performance when compared to other SSDs, especially with Samsung 840 Pro. There are certain workloads where the drive performs nicely, but in many tests its mediocre for an SSD.

In any case, ADATA is probably keeping this drive for mainstream users, although, for a product that uses the ‘pro’ word, I would like to have seen a higher-than-mainstream performance, at least somewhere between SanDisk Extreme II and Samsung 840 Pro.

Its strange to see that ADATA SP920SS is more expensive in the US in comparison with SanDisk Extreme II and Samsung 840 EVO then it is in the U.S. Samsung EVO 250GB makes a lot more sense for UK buyers compared to US counterparts. You should note that you’re getting only the SSD with Samsung EVO, and not the desktop kit that others give.

  • Desktop Kit
  • 3 Years Warranty
  • Decent Transfer and Boot Load fit for mainstream users
