The company is expected to introduce a new line of SSDs at next week's GITEX Tech Week 2016 event in Dubai. Legit Reviews has a bit more information, which is based on a PC Mag interview with WD that has since been deleted because it was published too early:
So, WD is getting back into the SSD market with the WD Green SSD and the WD Blue SSD and we have a feeling that this time it will be for good. It really can’t go worse than it did than the first time around and the SSD market has really matured in recent years. The first time WD entered the SSD market it was considered a ‘small’ $400 million emerging market and in 2015 that small market blossomed into a massive $13.8 billion dollar industry with 100 million drives shipped. The market has only grown this year (2016), so hopefully WD will release some solid drives next week if they want a piece of that pie.
