    I am looking for some help here. I have a Vaio FW245 and my data transfer speeds on both eSata and USB have gone from poor to worse. When using USB transfers, I cant get better than 30mb/s...eSata for some reason is down to 10mb/s....the best its ever been for both are 40mb/s and 50mb/s respectively. The other symptom is that speeds use to start off high and then drop to half of whatever the max speed was by the time it finishes. Most of the files that I transfer are 1gb or larger (movie backups)...the total file transfers typically exceed 10gb at a time. With speeds this slow, it takes an unbearable amount of time to do both data xfers and large backups.

    I recently upgraded to a 7200rpm 500gb hardrive (from a 5400 500gb drive) and noticed no real change in xfer speeds.

    Any help in understanding what is going on and/or tips on how to improve performance would be greatly appreciated.

    usb 2.0 speeds around max. 30 mb/s are normal, the interface is the bottleneck. eSATA should perform much faster (it should max out your hard drive). I think your problem is software related. To better identify, please run a HD Tune benchmark on the drive connected to eSATA and post the results.

    please also tell how much space is left on your built-in hard drive and check the device manager settings like write back cache.

    Thanks for the response. I will post my HD Tune benchmark results later. The hard drive that I am using has about 50% of the 1TB avail. How do I check the write back cache settings? What should they be set at?

    You running antivirus software? It'll slow down file copies big time.

    i have the same prob w. the external esata 2.5" enclosure. the drive is a 5400rpm but i usually get max speeds at 45mb/s and lows around 28mb/s...is it kuz the external enclosure is cheap or the cable is cheap?

    ^Try disabling antivirus when doing file transfers like this.

    You're Hitachi looks like it's doing well. I have the same model and love its speeds. What's the spin rate of your external 1TB?

    I've got a 2TB external @7200 and my Hitachi as a 2ndary internal @7200 and I get sustained xfer speeds of 70-80MBps, sometimes higher... sometimes lower. I usually copy movies and bluray files back and forth, so my average file size to xfer is 3-8GB, as high as 20-30GB.

    What Intel chipset driver are you using? Are you keeping your drives degragged? I've got MSE running for antivirues. Neither it, nor Avast, ever got in the way of data xfer.

    File size and fragmentation can degrade transfer speeds.
    Small files can really drag things down.
