I am trying to copy files from a 750GB drive (HD from a dead laptop) to my PR4100 for archive. I’m using a PC to manage the operation. BTW, the laptop HD is using a SARBENT SATA-II to USB 3.0 adapter.
The XFER rate is a miserable 20MB/s. I was originally using the PC with wireless only and was even worse at 1-2MB/s which I then changed to 1GB/s ethernet connection to achieve the 20MB/s rate.
I have the laptop HD plugged directly pluuged into the PR4100’s front USB port.
To me, it looks like the PC is in the data path. Can I do a direct disk-to-disk transfer on the PR4100, avoiding the PC and so increasing the transfer rate ?
You may want to ask your question (if you haven’t already) in the dedicated PR series subfroum where people more knowledgeable about those units may be able to assist.
For the single bay My Cloud units, the subject of this subforum, one can attach a USB drive to the single bay My Cloud USB port and copy data, however the data transfer rate is typically not very high (not the max capable of a USB 3.0 port). Instead WD recommends, for the single bay My Cloud units, to attach the USB drive to a computer and copy the data to the My Cloud. It is best to use a wired gigabit connection for both the computer and the My cloud. Wireless is almost always slower than wired Gigabit.
There are a number of factors, including file size and number of files, that can impact the speed of data copying to a My Cloud.
Bennor,
Thanks for the suggestion of using the PR4100 specific forum.
I think this was a general question for WD NAS devices. Seems like there is no capability to do a disk-to-disk DMA transfer.
Seems a bit nuts to me that the 2 drives are presumably connected on a high speed bus but cannot talk to each other directly but need to copy the data over the network. But what do I know
Have a great day…
