Sorry.. trying to figure out this bottom post thing.. cant seem to get
the quote or > thing working yet.
I dont recall reading that option in a reply previously, but that is
interesting. I am not sure how to check for that, I can figure it out I
am sure. However, I would guess it is not an issue. I typically turn off
that stuff on my machines as I have a pretty decent hardware firewall in
place at my router which is Unifi/Ubiquiti hardware. Doesnt mean it may
not be an issue.
In reply to another post.. using Task Manager to see disk usage.. I am
currently copying a 300GB DNxHR video from the SSD over USB3.1 to my
local internal HD. The copy speed indicates 40MB/s, in Task Manager, it
shows a bit over 80MB/s, which I assume accounts for the read from the
drive and the write to the drive... not sure though. So this strikes me
as one problem. USB 3 is 5Gb/s. Or about 500MB/s.
An internal rotating platter disk should get a speed of about 80..120
MB/s.
USB 2.0 has a speed of 480 Mbit/s, so you could get a speed of about
40MB/s, max 48MB/s, which is similar to what you are indeed getting.
Another limiting factor is that continuous write speed on SSD devices can
be slow on older or cheaper models. To make sure, you could attach a
rotating USB3 disk and try. Or attach your USB3 SSD disk to other
computers and try, to find out what is the limiting factor.
If you were using Linux, I'd suggest:
hdparm -tT /dev/sdXY
to test the raw device speed (read). There must be applications in Windows
to do similar tests, but I can't say which.
As one of the drives
is an SSD.. this seems ridiculous to me that it is basically moving at
USB2 speeds. At the very least, as it is over a USB 3.1 gen 2, 10Gb/s
wire... it should be much much faster than this. So now I am left
wondering why my system is super slow at copying files. Is there some
configuration in Windows 10 that has to be enabled to allow fast
copying?
I don't know. In the case of the external disk above it seems a hardware
limitation. Either the disk or the USB3 interface of the disk or the
computer.
