I've updated a number of SSD's and HDD's lately, it was probably not 100% needed but it certainly feels better reading the changelogs with fixes, and reading accounts from search results of the (few?) people who got into trouble with older firmwares. Just googling your model returns some results with a more recent firmware version. So it exists, but its preferable that you find one published by your laptop vendor. Although at this stage, I'd probably just back up my data, and then flash regardless, not much to lose really.
