what file system are you using? ssd drives have different characteristics that need to be accomadated (including a relatively slow write process which is obvious as soon as the buffer is full), and never, never put a swap partition on it, the high activity will wear it out rather quickly. might also check cables, often a problem particularly if they are older sata cables being run at a possibly higher than rated speed. in any case, reformating it might not be a bad idea, and you can always use the command line program badblocks to exercise and test it. keep in mind the drive will invisibly remap any bad sectors if possible. if the reported size of the drive is smaller than it should be the drive has run out of spare blocks and dying blocks are being removed from the storage place with no replacements.
