NikKTech reviewed the ASUSTOR AS1004T V2 NAS Server
A quote from the article:
ASUSTOR AS1004T V2 NAS Server Review
Equipped with a 60% faster Marvell Armada 385 SoC resulting in overall performance gains of 20% the brand new AS1004T V2 NAS by ASUSTOR offers a much higher bang for your buck compared to its predecessor the original AS1004T.
As NAS servers become more popular just like with any other segment of the industry competition between manufacturers grows even stronger and that means they are presented with two valid choices/options either design, manufacture and roll out brand new models or save both money and time by upgrading existing ones with the latest hardware components. This of course is nothing new since we've seen it countless times over the years in most areas of the industry from electronics like TV screens, speaker systems and PC related products up to even cars so it's really nothing we can or should complain about. ASUSTOR released the AS1004T NAS back in late 2016 and after a somewhat successful run they decided to give it a boost by upgrading its hardware components and releasing it once again as the AS1004T V2 model which has been with us for roughly two weeks.
