Pros: Good price for a 128GB SSD. Drive was plenty fast and worked as it should. Comes with extender tray and a 7mm to 9mm spacer for laptops.

Cons: Beware, the 128GB and 256GB versions have slower write speeds than what was advertised. The box the drive came in showed that only the 512GB and 1TB model have 500MBps write speed were as the smaller capacity versions only have around 360MBps write speeds.

Overall Review: I was debating between the ADATA SP920 128GB SSD and the Crucial M550 128GB and went with the ADATA based on the tray and software that the Crucial does not come with. Apparently, the drives are very close in specs and hardware but the Crucial doesn't have the write speed penalty on the lower capacity drives. Still not sure if I made the right choice knowing now how much slower the write speeds are.
