Data transfer copy speed

Hi!

What kind of copy speed can one expect? I get like 20MB/s which seems slow (copy on the same HDD)? (but still faster than copy and past when i got 2MB/s).
I need to change my account name and therefor I need to copy my whole user folder of 90 GB and it takes forever...

Is there something I can do to speed things up?

Regards Martin

Hello. Take a look at this tutorials.
Search on for Speed up Hard Drive performance.

don't forget transfer speed also depend on the cache size and RPM of your HDD/pen drive ect

Hi and thaks for the reply.

I have loked at the tutorial and adjusted all the setings to maximum performance but still I think it's slow.

I have 4GB of 800MHz ram and a WD GP 7500rpm SATA 16MB so I figure that it would be rather fast (vista performance score on RAM 5.9 and on HDD 5.6 and CPU 5)

If it was not for my girlfrend I would go to Ubuntu (or however it is spelled).

martins77,

The first thing I will say is that the data transfer should be done by now if you just let it go.

Also keep in mind that the more small files involved, the slower the transfer will be. On my system I can get over 50MB/sec copying a 50GB file from a SATA drive on a motherboard connector to a SATA drive on a PCI RAID controller. Conversely, if I copy 30GB of 30MB files, I only get about 16GB/sec. This gets worse when you copy even smaller files.

No version of Windows has been particularly fast at copying files.

Thanks for the info!

I did not quite understand the first sentence (I posted the message a few days ago so yes it is done copying by now..)

I also have a SATA drive (but only one) so I have not set it up to RAID (pointless for one drive?)

When I start the copy I have a speed of 40MB/s but then it rapidly drops to 20MB/s or lower.

I was hoping that having a dual core, 4 X RAM and a faster HDD would speed tings up for med but it does not seem to make any significant difference compared to my older XP system.

You could try disabling the Remote Differential Compression although I believe it mainly improves network transfers. Vista still takes ages to simply copy files from one disk to another on my local machine, the speeds you are reporting do not seem excessively slow. Have a look at the tutorials on improving your system performance, in particular those relating to disk drive performance. Also have a look at the properties of your disk drive in device manager and make sure DMA is enabled, although I think your transfer rate would be MUCH slower if it wasn't.
