HDD to HDD transfers seem too slow

[cameraman77]

Folks:

Been surfing the threads about HDD to HDD throughput issues. I would like to toss mine in the mix and see what inputs I can gather (or links to other threads).

I have a relatively new build running W7 Ultimate (x64) on a i7 990 using an eVGA X58 SLi3 mobo, 16 GB RAM, with a SATA 2 SSD for the main boot. All my HDDs are SATA (NTFS) and the two drives in question are not dynamic .... yet. The mobo is set to IDE compatibility ..... for now. When booting, BIOs reports the HDDs are running in Ultra-DMA 5 and SMART is enabled. Here's the problem:

1. My Western Digital 1 TB NAS gave up the ghost and the NAS circuit board failed (it had a fair run). I connected that HDD directly to an open SATA port and W7 saw the partitions on it. I used a Ubuntu boot CD to mount the volumes and managed to recover all the data off of the recovered 1 TB HDD to a 2TB HDD (both of these drives are SATA). The total transfer was ~567 GB and took ~4 hours to complete.
2. I blew away the 1TB partitions under W7, re-allocated the disk completely and did a quick format.
3. Now trying to get all the recovered data put back onto the recovered and freshly formatted 1 TB BUT seeing transfer ates that are well below even ATA133 standards. The transfers start out strong (~13 MB/s) but quickly dwindle, after an hour, to and hold at ~1.03 MB/s ...... . I am guessing, at this rate, that if I allow the transfer to complete, about 4-5 days will have passed ...... . There is ONE zip file at ~165 GB, a couple of DVD ISOs, and the remainders are around 15-20 MB each (digital photography). Much of the slow transfers are occurring when handling my 10-25 MB files.

Ssssooooo, here are the questions:

1. Is converting the HDDs to AHCI and dynamic going to buy me anything in terms of improved performance? I am planning on doing such a conversion but may not if it will not gain me much.
2. What am I missing that will give me the transfer rates I should be expecting?
3. What else can be suggested here?

Thanks!

Simple use superantispyware and scan for hackers ,spywares ,and scan for virus with avg or kaspersky before scan update all antivirus, then try unstoppable copier

Load bios default settings before start

Setting it to AHCI will improve performance and it's also something a SSD can appreciate due to the more advanced instruction set it provides. It will however most likely require you to reinstall windows. Recommended provided it's worth the reinstall hassle to you. Performance increase could be worth it though.

You can switch to AHCI without reinstalling windows, at least for win 7.

I don't recommend converting to a dynamic disk though, unless you will be doing software raid from within windows.

Folks:

Thanks for the responses.

After finishing my transfers, I did check for any spyware but none was found (this is a fairly recent build ... within the past month) so I don't think there was a lot of time for the system to be compromised). PLUS, one of the first things I did was load a security suite (Comodo) right after the inital install so that is likely not it.

hitechgowthaman, I did try reloading the BIOS defaults and reconfig'ed from there. No improvement.

roald, I finally enabled AHCI using the process referenced by Hawkeye22. No improvement there either.

Any other ideas?

Thanks!
