No Surprise
After a decade of buying only Seagate, yesterday I took delivery of a Western-Digital HDD. Personal experience with failed Seagate drives and their [in my opinion] unacceptable customer service, or lack thereof, forced this move.
Seagate has lost the HDD market and W-D appears to me to be the Heir-apparent. I'm sure others have faith in other HDD makers. I'm sure Seagate still has their followers; I'm just no longer one of them.
The layoffs are certainly sad for those affected, but not surprising to those of us who both watch the industry and bought Seagate products.
