I own a BluRay writer. A few years ago I had a serious attempt at BluRay archival storage. It works - but it's slow (very slow) and expensive. Then there is the cost / GB - that remains high due to the low volume of BD-RE media sales...
Now factor in the super high volume of MLC NAND flash SSDs prevalent on today's mass market. A good SSD will last far longer than the slowly degrading dye on a BD-RE disc. Just dust off an Intel SSD every 5 years and to run a level 2 Spinrite scan on it and it could potentially hold data for decades... No optical media could match that...
