I have a computer built to acquire uncompressed 2048 x 2048 16 bit images at 100 frames per second in real time, writing to disk. A RAID0 of SSDs is thus the only option.
For the past month or so, this setup has worked great. Recently, however, the frame rate has been sporadic during data acquisition, indicating that the disk write performance has dropped. I believe this is most likely due to the fact that I have completely filled and emptied the disk array multiple times and the performance of the SSDs has degraded since my RAID controller doesn't pass TRIM commands to the drives.
Is there any way to restore the performance of the array?
