I would contact RAYCUE and get the recommended SSD drives from them. Am sure they have done tests to verify the operation of the device with various SSDs so they should have a list of drives that they used to test..
FWIW, without a recommendation from the manufacturer, getting reliable interface to the SSD or even have it work can be hit or miss. This can be true for any external DIY enclosure. As a general rule, "bargain" drives are the least reliable though getting popular brands are not a guarantee either. From personal experience, Samsung Pro series and WD Black series have seemed to be most successful.
