Why did management skyrocket their dividend payments 350% over 4 years? That seems very foolish. They should have just increased it like 10-20% per year. And how are they going to pay $195 million per quarter if they're only making $50-$100 million?
I use a lot of Enterprise SSDs mainly for database queries I run. I can tell you that the best SATA III SSDs are by Intel and a distant second & third is Micron & Samsung. The best SAS SSDs by far is made by HGST and I'd say Toshiba is close second -- Samsung has very few SAS SSDs. I use these because they are cheap on the used market aka eBay.
The future, however is in the NVMe flash drives which are dominated by Intel & HGST (based on old Virident technology). These NVMe drives have IOs that are 5-10 times as much as the old SATA SSDs. I think the HGST FlashMAX drive even does 3-4 Gb/sec reads.
Anyway, Seagate's SSDs are indeed mediocre. They are expensive and have middling performance -- similar to the Micron SSDs which are mediocre as well. None of this matters right now since they can continue to sell Enterprise disc drives to the Cloud/Rack/NAS/SAN market but eventually it will matter when flash becomes cheap enough but that could be quite a while.
