Windows 8.1 has problems to detect the Raidr as an SSD.
Point 1: If installed on the Raidr the Raidr is shown as a Hard drive in the menu where you can manually start to defreg/optimize the computer hard drives. The problem with this is that Trim does not work!
If you run winsat formal the drive get recognized as SSD and trim started to work. But i think not many people know this command and microsoft has hidden the System tool do analyze the performance. Worst case: A never trimmed Raidr.
Point 2: If you use the Raidr not for the os as a sedcond drive you can run winsat formal too. But it doenst let the Raidr to be reognized as an SSD and Trim ist not working.
Havent tryed that without a Raid on the drive. So i think its a bug with W8.1 and raided SSDs to be recognized as SSDs
