It is harder to get cheaper than $50 like the $45 WalMart wants for that Addonics and I swear by Addonics for their reliability but they have something else no one else has.... good tech support that actually answers questions on the rare occasions you'd ever need one since their stuff just works.
Youre right about the bitttechun transfer rate cause my brother is in vid production and while shoulder surfing one day i WITNESSED this ungodly fast transfer rate of some multi gig files while tapping his shoulder to hurry up we gotta get to the pub and he says just hang on a minute and I'm protesting why "that would take forever to copy files that large.... " but the copy finsihed before I could stop whining.
A good tip off for you and anyone else reading this after you realized I solved your problem, notice the gold stripe on your example pic, that is one of the few industry standards you can rely on as consistent as it indicates a PCCard (PCMCIA II) capable card and is a requisite for any PCMICIA device faster than a modem cause the data transfer rate can be 50+ times faster over PCCard than older PCMCIA cards that will feel like watching elderly snails screwing as files lumber along. It has to be mentioned since there are still old PCMCIA 1 standard adapters even still for sale capable of mounting large capacity CF and SD/SDC cards that seem to insult data transfer instead of facilitating it.
You're welcome to insist just on PCCard or USB 2.0, but it won't properly serve your cards transfer capabilities as well as that PCExpress card. Is your requirement for PCCard / USB interface because you don't have an Express2 slot ?
I hope not since you'd be facing the same legacy tax shoppers of IDE SSD's encounter just like car owners with freon Air conditioners get slapped with as mechanics sypmpathejically shake their heads explaiaing the rules, blah, blah. You're not gonna get the best of both worlds and Googlefu would've exposed any RadioShack soldering tricks to enable cheap, safe conversions of a PCMCIA adapter for this fastazzer card you're flipping back and forth in your hand at this very moment researching the ultimately cheap alternative.
