Windows 7: How to copy files between two hard drives faster?

Now, I have just moved a large (4.3 GB) file between two partitions on the same disk (Samsung HD 103UJ). The speed was around 31 MB/s, then towards the end became 35 MB/s.

You mentioned bad partitioning of disks. What did you mean exactly?

Drives that contain partitions not aligned to storage track boundaries (on most disks, this is diskpart using align=64), and/or are formatted using incorrect (or poorly-chosen) cluster sizes based on the type of data to be stored (8-16K clusters for volumes storing lots of small files, 64K clusters for volumes storing large files or meant for large sequential file copy operations). Windows 7 by default formats NTFS with 4K clusters, and aligned at 1024K, which is fine for OS disks (relatively speaking), but is likely not going to be fine for storage volumes (or heavily-used disks).

Uniflex,
Robocopy is excellent, very solid, very fast, used by many network administrators.

Robocopy has more power and features than the earlier versions thereof.

I think that when I bought the second disk I simply used the Windows 7 tools to partition and format. I looked now briefly at how to re-partition, but the Shrink tool does not seem to have options that advanced. Any suggestions on a (hopefully free) good disk management app? And while we are at that, I think I can take all the data away from a drive, re-format and put the data back in, but can I do the same with the OS without re-installing?

Right now i copy about 6 GB from the HDD - WD 6400 AAKS, to USB stick.
The copy speed is 4.42 MS/second
Isn't that to slow ??!! Can i improve the speed ?
The files are small, about 30 MB, each.
When i copy some bigger files from onn HDD to another ( i have 2 HDD WD 6400 AAKS ) is much faster.
Thanks.

First, it's good to keep in mind that USB is a "bursty" bus, it's not meant for sustained file transfer - if you want external transfer speeds that are consistently high, you use Firewire. Of course, I don't know of many fireware memory keys .

With that said, USB keys have their own speed limits based on the type of memory inside, and how it's ordered. Back to your numbers, 4.42MB/sec is ~35.5Mb/sec, so you need to know what the maximum transfer speed of that USB stick is. I'm betting it's probably between 35 - 40Mb/sec, as most non-HDD USB devices I've seen are not rated much faster than that.

4.42Mb/s is likely due to the USB stick, lots of them only reach that sort of speed. You have to pay a bit more for decent speeds of 20Mb/s+.

Your HD speeds being a bit low is probably mainly due to copying lots of small files, this really hits HD performance just about always. I would run ATTO disk benchmark (|MG| ATTO Disk Benchmark 2.46 Download) as it does read&write benchmarks at small to large file sizes.

Use Partition Wizard.

You will not need to re-format your drive.

I'd like to add, that these problem seem to be confined to internal disks, strangely enough. I have an external hard drive connected via eSATA, and transfer rates to and from this device are way higher that between internal disks. This does not make sense at all. We are talking about same internal disks - with or without their formatting problems, but why would a transfer rate from the external drive be higher then between different partitions on the same internal drive?
