RT-N65U usb3 speed issues

[bytat]

SmallNetBuilders review of the router reports writing speed of 17.6 MBytes/s and reading speed 30.8 MBytes/s on an NTFS formated drive over LAN.
On my NTFS formated, usb3 enclosured ssd drive I only get around 7 MBytes/s writing speed and 22 MBytes/s reading speed.
My main concern is of course the writing speed discrepancy. How can this be? Is there anything I can do to increase the speeds?

In some unscientific testing I've done (and some I've posted on here, I can try to dig up and link to later) I've found that file size (larger files go faster) and exact pattern of test (does it do writes then reads, or lots of sequential writes followed with lots of sequential reads) is a very large factor influencing throughput, and so is the USB to SATA interface in your external device, some are just faster than others.

Try same drive & same enclosure plugged directly into your PC to measure a baseline then compare with drive shared from router w/ PC connected via gigabit.

Also I wouldn't use an SSD connected through the router myself (though I have just for testing). A mechanical drive's throughput will not be the weakest link in a sharing through the router situation and the router's lack of SSD specific OS level hardware awareness (such as TRIM) will wear the drive at an accelerated pace.

Well, I can't test it directly on my pc since it only has usb2 connections but when connected to my macbook pro I get ~300 MB/s write speed, ~400 MB/s read speed.. When testing the mac connected ssd over lan, from my pc to mac through the router, the pc reports ~37 MB/s write and ~40 MB/s read.

I'm only using the ssd for testing purposes.. The goal is to buy an external 3.5" usb3 harddrive but first I need to know that the router can deliver the speed. Right now I'm using the pc as NAS because of the seemingly lousy usb3 performance on the router.
