USB2 faster than PCMCIA? For CF transfer to Laptop?
jsut a question.. i jsut bought a Sandisk CF to PCMCIA adapter and running it with Ridata 2gb 150x CF cards...
Now i was always of teh assumptin that PCMCIA was faster than USB considering it didnt route through teh USB bus pipeline... But it seems hts actaully a little slower??? Any ideas? I bought it to save me from havni got carry around one fo those all in one card adapters, asl i only really need CF and SD/MMC ( SD.MMC is already built in) SO i tried copying and pasting etc.. and it was markedly slower... well its either that or im losing the plot... any ideas?? IM wanting the fastes card to HDD transfer speed.. as im using a 5d, i was thinking aboutthe wireless networking transmitter... but thats like over a grand or so and its really not needed.. not yet.. |

Are you truly using a PCMCIA slot or an in-built card reader?
On my book the in-built card reader is clinically a USB device. If your in-built card reader is USB, and it's USB1 as well, that could be your problem.

I have a PCMCIA CF reader and its also as slow as molasses. Thats when I found out it was only 16-bit and you need a 32-bit PCMCIA reader to really speed things up.

yeah i notieced that to Tommy.. PCMCIA runs lke a bag of... yeah anyway.. turns out theres a Expresscard adapter which runs about 5 to 8 tims faster (as fast if not faster than USB2
This expresscard stuff is for laptops running PCIe chipsets... but i only fond this adapter from one US retailer who was chargina fortune for it.. when u consider USB2 adapter is about 10bux.. i thnk il just stick with that.. |

Peter, is this Expresscard adapter you were talking about? $59 MSRP doesn't sound too bad but doesn't seem to be out until next week.

I thought CF cards had internal speed limitations...like 20x, 60x, 80x, etc...

Hey Ben,
yeah they do.. different generations have boosted speed... im running 150x CF cards which is about 12 to 15mb per second... theoretically, reading the card should be faster, but its not.. on a 2gb card shooting 12mp RAW @ 12mb each, you got about 65 images. Theoretically it shouldnt take more than 3 minutes to transfer on a 5200rpm laptop HDD last transfer i did through USB2 took 13 minutes which is slower than burnign a DVD.. and thats through into a 7200rpm ide drive these express cards apparently run 5 times faster than ide.... or was it USB2.. i cant rememebr now.. |
