Works great

ByRichard Smithon November 17, 2003

Verified Purchase

The Jumpdrive Trio works fine for me! I have had no problems with it except that I had to download the drivers for it before I could use it - but that is only a minor annoyance.
It has worked with any memory card that I have put in it and it works quickly and error-free. But, best of all, it reads (ans writes to) my SD and MMC cards easily and at a lower prices than other card readers. Recommended.

nice product

ByA customeron May 8, 2003

Verified Purchase

I just got a jumpdrive trio a few weeks ago. I use it as a memory stick reader to transfer digital images and as a USB drive. Its great that it doesn't require drivers(Win2K/XP). All other memory stick readers I have used were much larger and required installing drivers. If you have a spare memory stick or MMC/SD card laying around, the jumpdrive is a great way to turn it into a USB drive for transferring files. Here are the transfer speeds I got using a 64MB Lexar memory stick.
- Used a 46MB Test File
USB 1.1 Port: 65 sec to write, 55 sec to read
USB 2.0 Port: 45 sec to write, 45 sec to read
From what I understand the memory stick media is likely limiting the speed. Pairing the jumpdrive with fast MMC or SD cards will likely show faster results.
The only concern I have with this device is that the plastic body and hinge feel somewhat fragile.

Passes the wash test

ByJason N. Weddingtonon October 18, 2004

Verified Purchase

The plastic cover for the USB connector never stayed put and I lost it after the first week. That being said, I've been toting the Jumpdrive Trio around in my pocket and in my backpack for over a year (without the plastic cover) and it hasn't broke yet. It's even been washed once because I forgot to take it out of my pocket. I let it sit in a sunny window for a day and both the drive and my 256 mb Lexar (Sony compatiible) Memory Stick still work to this day.

The Jumpdrive Trio is a little larger than standard USB "thumb" drives with built-in memory, but this has rarely been an issue for me. If your computer is equipped with front USB ports than this is not a problem.

Overall, this is a great product for the price especially if you have other devices (PDA, Digital Camera, etc) that already use SD, MMC, or Memory Stick media.

It's useful, but not very sturdy and I keep losing the cap

ByAmazon Customeron July 11, 2004

Verified Purchase

I like this because it reads the SD cards in my digital camera, but I am not using for a portable thumb drive like I thought I would.
The main reason it hasn't turned out to be a device I use everyday is because the cap keeps falling off. I have to keep it in its own pocket in my bag because otherwise the cap gets lost. Also, I found it popped open once (exposing my SD card) which really concerned me. The other reason I don't use it all the time is that it's so big, I have to connect it to a short USB extension cable to fit it into a USB port alongside other devices. (But a short USB cable was included -- very nice.)
Rather than being indispensible, this device turned out to just be my backup card reader. Usually I just use my SimpleTech Mini FlashLink for a card reader, which is a sturdier and simpler card reader (even though it's not USB 2.0.)

easiest way to make your SD/MMC/MS/DUO becomes thumb drive

Bymatt.mingkeeon December 27, 2005

Verified Purchase

this little adaptor simply does the job
it accepts ONLY one card at a time, since I have a spare 2GB MS Pro Duo (video for PSP), I can store this card as well as make it thumbdrive
SD/MMC/MS works without problem
MS (Pro) Duo also works without additional adaptor, just insert it carefully along the right side, and you may have hard time to pull it out (only a little bit left exposed)
other variants (MMCmobile, RS-MMC, miniSD, microSD) requires adaptor
it has a drawback of this adaptor, that the USB cap falls off easily, and make sure the card cap closed all the time
this little adaptor is highly recommended for digicam, pda, PSP users
update: this reader can use on 2GB and 4GB SD cards

VERY Durable! Good Buy!

ByMicheleLKon February 2, 2004

Verified Purchase

If you're like me, and you have a PDA and/or Digital camera that uses securedigital cards, you can't live without this thing!
HotSyncing music and movies with Palm software can literally take HOURS if you do it with your palm. However, if you build up your MP3 playlist or add a movie to your SD card using this little drive, it goes SO FAST!
With this I am able to bypass my digital camera's software, my palm's software and get out the door faster.
The best use I have had for it so far - downloading something at school on a faster connection than I have home, then carrying it home with me that night. It's much faster (and cheaper) than burning CDs or emailing a file to yourself! It's small size is perfect for my purse, and even though it's light, it's very durable!
5 stars from me!

Very nice little device

ByMKS in San Anon July 30, 2006

Verified Purchase

Pros: Incredible flexibility -- a must-have for digital photographers and tech-types with a variety of portable memory. That is worth 5 stars alone.

Cons: A device this small and portable needs security during transportation and this device loses points for its total lack in this area. I created a dummy cord for the cap and a connector for a key ring/lanyard. Any company that understands tekkies on the go should have attended to that detail.

Overall: Well worth the money -- if you're willing to take a minute to secure the parts for portability.
