This is a 4-bay unit. The unit is in excellent physical condition --- very clean --- and perfect working order. The firmware on the unit has been updated to latest version and reset to factory defaults. New user will be presented the "Welcome - Smart Installation" when they power-up the unit.
The unit ships with original packaging and all original accessories, including: power cable, 2x CAT5e Ethernet cables, screws for HDD bays, drive bay lock keys, and quick start guide. These drives have different amount of power-on time, and as shown in the image one has a "Warning" state (sector read error). The RAID array has been erased and will be reinitialized the next time the unit is configured. I had been using this up until last month with no problems despite the warning message. I have included the drives because I have no need for them without the NAS.
The drives can make a great "starter" set, and you can migrate to new larger drives one at a time. Or, you can experiment with the NAS using the existing drives, and then replace with your own drives.
