Startech USB 3.0 Expresscard 34 Card

Bygdouglas2501on January 12, 2011

This is a two port super speed USB 3.0 Expresscard Card. The driver does not come with the product but is easily obtained from the Startech website. I downloaded the driver for 32 bit Windows 7 before the item arrived so that when the expresscard arrived I would just plug in and play. The expresscard did not recieve five stars because the expresscard DID NOT come with the external power adapter. The external power adapter is necessary for the expresscard to provide enough power for USB 3.0 powered devices. USB 2.0 devices work fine with the expresscard without using the external power adapter; I tested several printers, flash drives, ipods, USB 2.0 external powered hard drives, Evo 4G (including USB tethering function, disk drive function, and charge mode), and SDHC cards (using usb adapter) and they worked fine without using the external power adapter. The only real problem I have had with expresscard is when I plugged in my USB 3.0 Western Digital My Passport Essential (500 GB) hard drive (a portable hard drive that is powered entirely by USB port) and started a write operation the expresscard port would "eject" the expresscard. USB 3.0 ports are designed to provide 80% more power than USB 2.0. Thus when I tried to write to the My Passport Essential hard drive using the USB 3.0 ports on the expresscard, the device would attempt to draw the full power of a USB 3.0 port, which is greater than what the expresscard port could provide and therefore my computer would "eject" the expresscard. That problem is completely solved when the external power adapter is plugged into the expresscard. I was transferring data (180 GB+) from an USB 2.0 external hard drive to the USB 3.0 Western Digital My Passport Essential while using the USB 3.0 expresscard with the external power adapter the USB 3.0 Western Digital My Passport Essential was 50% faster than when it was using a USB 2.0 port. Since the limiting factor in the data transfer from the USB 2.0 external hard drive to the USB 3.0 hard drive is the transfer speed of USB 2.0 hard drive, I suspect that speed of the USB 3.0 expresscard is actually much faster than stated above.

A bit disappointing and frustrating at first...

The disc that is enclosed is very confusing, if not worthless. I had to go to the StarTech.com website to download the latest driver. I have a 64-bit Satellite dual booted with Windows 7 Professional (x64) and XP Professional (x86). I only found one driver for this device. When I tried to load on Windows 7, it was installing into "Program Files (x86)," so I stopped the install and contacted StarTech via chat. I was told that the one on the website is the latest, and it works on both x64 and x86. The technician did not seem too well versed, as he admitted that he had no idea where the software installed. Anyway, driver installed in Windows 7 with no problem; however, in XP I had to tell the Hardware Installer to load driver from D:\Mos24Ser\winxp (note: change D to where XP Professional is installed on your system).

My next problem was a very loose ExpressCard/34 in my /54 slot. Very, very touchy! Seems that StarTech has a bracket to resolve this problem. (ECBRACKET). My personal (temporary) workaround is a carefully folded cardboard wedged beside the ExpressCard.

Then I tried to run my 500 Gig drive (housed in 3.0 Connected External Enclosure). I noticed a red led and a flashing blue one. The drive was constantly seeking.) I again contacted StarTech via chat AFTER waiting 25 minutes on the phone. This technician was on the verge of rude as he told me that I now needed to get an external power adapter "5V, 2000mah, Plug Type H, Center Tip Positive." When asked if StarTech had such an adapter, I was told "No." Having been a former Tech Support Engineer myself, I'd say that he's fortunate to not work for my boss. He implied that the problem was my fault for not studying the specifications. (OK, I should have, but that tech needs to learn diplomacy!)

So... drivers installed now, and Express Card happily powered with a Rhino 2500mA DC Adapter (set to output 5 vdc), I am indeed quite pleased with my new 3.0 SuperSpeed USB. My external drive is so fast that it rivals the internal one. Great product, but needs work on installation instructions and technical support.

Well worth the $20 price of admission.

Well I transfer audio book files as a daily practice. The average book run about 680 mb to 1.2 gb. I always have a book in my ear. It brushs away the boredom. Driving here and there can get pretty boring so I find a book is the least distracting for a dead arsed boring patch of time and still ads enouch juice to smooth out the day.

So anyway I find myself at the last minuite in a mad hurry to load up a couple of books for the road.

Now I normally grab 6 or 8 cd books from the public library , rip them in Windows Media Center and store them in files for the right time. At 2.0 USB from the desktop to a micro sd card to sometimes to 12 mbs really streches out the loading time when it drops to 4 mb per..., second.

I have noticed that moving files from the desktop to a 3.0 USB stick can reach about 50 mg per second.
However, when I am tranferring data from a 3.0 ssd hard drive thru the Star Tech Express unit to a 3.0 USB thumb drive I see the speed go down to as low as 4 or 5 mb per second. But that is still way faster then 2 .0 USB to USB speeds.

I easily found the drivers on Star Techs website, and most any 5.5mm 5v usb cord to power it from a notber USB port or a 5v charger like ones that come from a small speaker set do the trick l
