My Hard Drive to Hard Drive transfers seem slow...

[Will Eatforfood]

I recently bought a Samsung HD103UJ 1TB from ZZF,
http://www.samsung.com/global/business/hdd/productmodel.do?type=61&subtype=63&model_cd=249

and so I'm moving all of the data from the old 7200.10 250gb to the new drive and its going at 16MB/s. The time so far has been about 2 hours. This seems a tad slow, and I was wondering if the P5W DH EZ-raid port has anything to do with it. The 3 main SATA connectors are used up for the raptor, the 250gb, and a pioneer optical (Sata 1,3,4 respectively). I had to plug the 1tb as a storage into the the EZ-Raid port, but I thought a sata is a sata is a sata..? Anyone heard anything about this? I would HDtach but I'm still in the middle of the transfer. My silly self went cut paste instead of duplicating. :/

Edit. Is it because I'm making it transfer and delete at the same time as opposed to just transferring?

First, you should never "move" lots of data from one drive to another. Always copy the data so that if something craps out in the middle of the process you won't have lost anything. After the copy is complete you can compare them and if nothing was damaged delete the "originals"

That said, it sounds like the new drive is stuck in PIO mode rather than DMA. Assuming you're using Windows, the bottom of this article (http://www.microsoft.com/whdc/device/storage/IDE-DMA.mspx) tells you how to check on this and how to reset to DMA http://www.microsoft.com/whdc/device/storage/IDE-DMA.mspx

More than likely he just isn't copying one huge, sequentially written file. Small files and fragmentation will decrease your xfer rates. This is normal. During file copy, is your CPU (one core at least) pegged? If so you're in PIO mode, but this is very unlikely to happen on a modern system.

I'm assuming if they could be on DMA mode, they are since device manager>IDE>prop>adv shows absolutely nothing for the other drives except for the optical which is DMA4-5.

I also don't know why it is still seen as external disk instead of what it actually is. The drivers were automatically added by Windows. The other satas are on the Jmicron controller. Not sure if that applies to EZ-raid as well.

In case you can't see that, it was

117.8MB/s burst
Random Access 13.4ms
CPU Util 3% (+/- 2)
Aver. Read 84.3MB/s.

HDtach calls it External Disk 0 RGL10364.

i don't think SATA drives allow it.


something you could also check is to see if your old 7200.10 is set to SATA I that will affect transfer rates from drive to drive. this should be in the form of a jumper. check your hdd to see if its on.

Being set to SATA 1 will not cause any appreciable difference for that hard drive.

well, i was more leaning towards using sata 2 but would that make any difference on the 7200.10?
