Fastest Portable Hard Disk????

    The X-Drive VP6230 claims to very fast and I have seen reports of 12mbs when
    copying from the card.

    The PD70X claims to be the worlds fastest at up to16mbs (under 2 mins for a
    1GB CF)

    The NextoCF also claims to be the world's fastest at up to16mb/s.

    So, has anyone used these for real and if so, how fast are they really? (ie
    for a 1 or 2Gb card)

    I really want speed, as my original Image Tank is just soooo slow..... but I
    am willing to sacrifice a little of that to be able to view my
    with the VP6230, but will go without the view if it is actually slower than

    Hi Russell,
    Personally, I like VP6230 better than PD70X and NEXTO although it's a bit
    pricey compared to its competitor.

    I have used three of them quite extensively and I decided VP6230 is the

    Few points :
    - Large 2.5" Screen.
    - Battery can be replaced.
    - View RAW, TIFF of most cameras
    - Music & Video playback (I would say these are bonuses, don't expect too
    much from them)
    - Reasonably fast transfer rate (although not as fast as PD70X or Nexto)
    - Very nice finish
    - TV output with remote

    Note : I sell them alot and I know what most customers want :)

    Thanks for the reply.... do you have any more accurate transfer speed
    figures? Like how long it takes to suck in a 2GB card?

    I am leaning towards to VP6230 but just want to make sure it's not painfully
    slow.... but then, anything will be quicker than my IT.

    In fact anything under 5 minds would be good, as I am sure it takes the IT
    15-20 mins for my 2GB card. :-(

    Heres some info for you Russell.

    Admittedly the benchmarks below are a little skewed in comparison since
    they have a different brand 40gb 2.5" drive in them, but it should give
    you an idea of the difference in IDE controllers on the two (benchmarks
    done with freeware HD Tune 2.10):

    This is a Samsung 4200rpm 40gb 2.5" drive inside a Shintaro portable
    (USB powered - two USB cables) enclosure (~$45, but obviously no card
    reader - portable drive only). It has a good IDE <-> USB 2.0 controller
    and manages a good throughput.
    HD Tune: SAMSUNG MP0402H Benchmark

    Transfer Rate Minimum : 15.2 MB/sec
    Transfer Rate Maximum : 23.3 MB/sec
    Transfer Rate Average : 21.7 MB/sec
    Access Time : 17.8 ms
    Burst Rate : 24.1 MB/sec
    CPU Usage : 18.2%

    This is my X-drive 40gb 3320. It obviously doesn't have a great IDE <->
    USB 2.0 controller as it appears to be the bottleneck in this transfer
    test. However, since this is the most recent release prior to the 6230
    (2 months ago?), I would guess that it could very well have the same
    HD Tune: VP3320 Benchmark

    Transfer Rate Minimum : 8.1 MB/sec
    Transfer Rate Maximum : 8.6 MB/sec
    Transfer Rate Average : 8.5 MB/sec
    Access Time : 17.3 ms
    Burst Rate : 8.5 MB/sec
    CPU Usage : 8.9%

    For comparison, here is my Seagate 250gb 3.5" Shintaro firewire/usb hdd
    enclosure's benchmarks (running on firewire). Very very quick. (but the
    fan is noisy :().
    HD Tune: ST3250823A Benchmark

    Transfer Rate Minimum : 28.5 MB/sec
    Transfer Rate Maximum : 33.2 MB/sec
    Transfer Rate Average : 30.9 MB/sec
    Access Time : 16.2 ms
    Burst Rate : 33.5 MB/sec
    CPU Usage : 5.5%

    Actually, I forgot to benchmark the CF card reader slot (also from the
    3320). You can see that in this case, the controller isn't the
    bottleneck (as the throughput is less than 8mb/sec, which the HDD
    throughputted), therefore ~6mb/sec appears to be the card's limit (its a
    Ridata Pro-2 80x 2gb CF card). That means it should drain the 2gb card
    in around 5 and a half minutes (2000 divided by 6, which is divided by
    60). Here it is:

    HD Tune: VP3320 Benchmark

    Transfer Rate Minimum : 6.3 MB/sec
    Transfer Rate Maximum : 6.4 MB/sec
    Transfer Rate Average : 6.3 MB/sec
    Access Time : 1.2 ms
    Burst Rate : 6.4 MB/sec
    CPU Usage : 7.6%

    I use the PD70X (bought from Hendryk actually). It's VERY fast. Under
    2mins for my 1GB Sandisk Ultra II. Great Battery life from my AA
    rechargeables too. It charges the batteries, has car adaptor and is
    simple to use.

    I only want fast portable storage with good battery life. I didn't want
    music or video, or tv out, or a screen (IMO small screens are useless
    for reviewing shots anyway).

    Hendryk got mine out to me ultra fast and was very helpful.

    Prior to this I had a PD7X which was still fast, but battery life not
    as good. And prior to that I had an X-Drive II 2060 which took around
    15mins to copy a 1gb card :(

    Yep I have the PD7X and that is fast and better than the Xdrive.

    Its a drive which does what I require, and yes I do find it hard on the
    batteries although I have downloaded 14 512mb cards on the charge with
    some in reserve. But it takes AA batteries which if you can still use
    alkaline cells if it becomes necessary - this I like.

    I'm happy with my PD7x

    i just received my PD70X a few days ago, this thing is smooooking, just
    the way i like it, although the body material seems a bit weak,
    especially toward the battery cover, the latches are easy to break off,
    my bet is just to leave your rechargeable battery in at all time and
    let the ac charger take care of the charging.

    Make sure that both lids swing free. Not sure with the 70 but my 7,
    card end lid did actually sever the pins and the lid came off - this was
    replaced FOC.

    these are the fastest device that i have seen and what's more if your
    out of battery power there are 3 alternatives, AC power, 12V car or
    stick another set of AA's in.
