i put the hard drive in a USB enclosure than plug that to my router usb drive. than i connect my PC to my router with a LAN cable. when i did that i got 30-40 MBps (the speed fluctuates for some reason).
the NAS never reach 40 MBps either plug directly to my PC or through a router. only when i remove the hard drive that's usually inside that NAS and put it in USB enclosure than plug that to my PC i get 40 MBps write speed.
why can't i get that kind of speed with my NAS? is it broken? should i return it? do RAID setting matter (i use my NAS in normal mode, no RAID. but the hard drive itself is capable of 40 MBps when plugged to the USB port of my router so RAID doesn't really matter right)?
