First we have to note that performance issues with SSDs may be caused by the drives themselves or a lack of TRIM/optimization. You may want to check with the respective SSD manufacturer.
Just in case this is an issue related to Intel® Rapid Storage I would advise to uninstall and re-install it. Please also provide the version (Help, System Report) and indicate if the drive is or was part of a RAID volume or acceleration (Intel® Smart Response Technology) if further assistance is needed.
This thread will be moved to Intel® Chipset Communities as it is not Intel® SSD related.
