14 DAY TRIAL // Seagate and Western Digital, as well as vendors like Synology, Thecus Tech, QNAP, Lenovo/EMC, Asustor, and D-link, might have sowed the seeds of progress for NAS devices.
Seagate and WD have been heavily promoting their own-brand network-attached storage devices, while the others have kept up their sales through the years and months.
That is why it is the belief of certain parties that NAS devices will experience a big sales rise this year, and in the coming ones.
2013 is set to end with 3.5 million unit shipments, and that number may double by 2015.
Right now, 50% of all sold NAS ship without HDDs, suggesting that the matter of appropriate HDDs is problematic still.
So far, only WD has made its Red series of NAS HDDs relatively known, so that's one reason for this. The other reason is the varying performance-price-capacity ratio.
