Hi what is fastest method to transfer data from PC to PC.

USB 3.0 or Gigabit over the lan?

Example.

1. I plug in my USB 3 enclosure into a USB 3 port and transfer the data.

2 Or transfer the data over my LAN at 1Gb.

Thanks

By the time you copy the data to the USB3 drive, disconnect it, move it to the other PC, connect it, and then copy the files a second time, I would say that directly copying over the LAN will be faster and less labor intensive.

Use the gigabit network, will be much faster and easier.

USB 3 has higher bandwidth capabilities, but you really won't see much of a difference between the two. The 5 Gb/s theoretical transfer speed of USB 3.0 will be bottlenecked by a standard hard drive read speed, which averages 80 - 110 MB/s unless you using an SSD for an external. I would go with a gigabit connection, roughly same speed, and easier like PhilFrisbie said.

Hi I just tested something.

I copied around 5GB of data from a sata 7200rpm disk that I have in a USB 3 caddy.

It took around 6mins to copy to the internal drive on my pc at an avg speed of 65MB/s.

I tried the same using usb 2 and it took a lot longer avg 32MB/s.

So is the R/W performance of the disks slowing me down?

Yes, most likely. What brand and model is the drive?

65MB/s look like the mechanical HDD bottleneck. Check if you have write cache enabled and also update usb 3.0 driver.

Hi it's a WD 400BD 40GB Sata I drive.

It's just somethig to test but I could buy a better drive.

My USB 3 card is a Pci 2 ASAKA 4 port device and it has the latest drivers.

Yeah, if it is 40GB, then definitely 65MB/s is fine (mechanical bottleneck).

How would I see faster throughput then?

I thought disk speed and not size would make a difference?

Thanks

For your 40GB drive, it is about right to have 65MB/s. Nothing you can do about it apart from enabling write cache. If you already had, then that is it.

Things that determine the speed of the HDD include rotation speed (rpm) and platter density (GB/cm2).

The drive is in a Icy Box USB3 caddy.

I can try enabling write caching.

But I can't do anything about the speed. It's a 7.2k drive.

Or you can get both in 1 (USB 3.0 gigabit NIC which can run at full 1Gig throughput). I'm getting around 90Mbps from Linux to my storage unit.

They aren't expensive either - just get one and try (i got one here www.usb3gigabit.com but there are some similar on amazon, ebay, etc)
