The Solidata X2-256 SSD
The Solidata X2 Series drives are housed in an aluminum casing that is brushed and then anodized black.
The back of the drive carries the label with the model and serial information.
As you can see, the side of the drive is typical of the 2.5-inch SSDs.
The data and power connectors are in the correct place so you will not have a difficult time using the drive in an adapter.
