i'm at the process to upgrade my NV+ to a faster NAS so I end up with 2 NAS 4 drives bay and 2 NAS with 6 drive bay.
4 drive bay
Netgear NVX
Qnap TS-459 Pro
6 drive bay
Netgear Pro Business
Qnap TS-659 Pro
The Qnap are faster than the Netgear (well on charts)
Nicer GUI interface
Seem to be quieter
ESATA and more USB
1 year warranty
Support well the link below
No vertical RAID Expand (As X-RAID2 or SHR)
Netgear
Nice box
Good speed
GUI is pretty normal
no ESATA
5 years warranty
support is good (for me with the NV+, one drive failure and got it replace)
X-RAID2 with vertical expand
I was thinking about to buy the TS-659 Pro for a more features and futur expandability (more drives) but after reading Qnap forum about problem with their RAID and also very slow or non support.
Now I think i'll go for a Netgear Pro Business
Here the link for Qnap forum. Be patient their is 19 pages for the problem !

PS: So before you spend your hard earn money on a Qnap NAS you better to take time and read the link above. Me after reading
this it let me a very dissapointing feeling about the reliability of Qnap NAS. And take in consideration also the Qnap only have 1 year warranty.
