I just bought myself a professional lexar card reader.
It's a USB 2.0 version. It's much faster compared to the current "no brand" one I have. But what makes it so much faster?
Isn't USB 2.0 the same speed for everything?
I don't understand what lexar does that makes them faster than an unknown brand.
It's not like there is a processor in there, right?
Someone care to share?
not all UDMA-readers are created equal, either... my current Delkin USB reader is UDMA but maxes out at 31mb/s so I'll soon be in the market for a faster reader if they exist
your extreme is a UDMA card.
all cards have a read and write capable speed. most read better then they write but up in these speeds at this point in time there are other bottlenecks that will slow things down a bit. your camera at this point probable tops out at between 25-30MB/s and that will vary with different brands of cards too as they use different innards to run the show internally.
so the answer is yes xfr rate is also determined by the card/reader/computer interface
The lexar reader you have is one of the fastest usb 2.0 readers out there. It maxes out the USB 2.0 bus. at 30Mb/s
A Non-UDMA card will be slower. But cards that are faster then the card you use now won't add any benefit to that reader.
We're all waiting for the USB 3.0 readers to come out. To get faster now you have to go Firewire 800 or eSATA readers. But until the next gen comes out everyone's holding their breath.
Yeah, the USB 2.0 readers ain't gonna take full advantage of a 60mb/s card... you'll need firewire 800 for faster download speeds than 30mb/s, or an expresscard reader (my next purchase). Even Firewire 400 is slightly faster than USB 2.0 AFAIK.
I was using a lexar FW800 and it was flaky. I didnt like the construction personally as the cards just didnt go in smoothly.
Ditched it and got an internal SATA reader that fits in a floppy slot. Blows every other reader out of the water! Had been looking for one and found reference to it on Rob Gs site. Although I think he is an opinionated buttflea the hard data is usually correct and he showed this reader clearly leading the pack of all other readers, by a long shot on most. The next fastest is a Lexar PC card for a laptop. USB is too slow for my tastes. Same UDMA Sandisk pro 16GB took 14 minutes to empty on USB 2.0 Sandisk reader, just under 4 on FW 800 Lexar and less than 2 minutes on the internal SATA reader.

Your PC does need to have sata ports and support hot swap on those ports or you have to get another controller card. Most will support it if you have raid and enable raid spanning on the device.
thanks for all the replies.
Should have asked earlier. I bought two 16GB 60MB/s cards... And 30MB/s would have done the same job
Lesson learned Luckily I didn't buy the 90MB/s hehe
My poor wallet
Well not really. you have to be careful with terminolgy. They all do it including internet service providers. You have to watch the Mb and the MB in transfer rates. I have two of the 16GB Ultra Pro cards and there is quite a difference in transfer speeds but its also limited to the reader you use.
With the 90MB cards I get actual of 75 MB/s from Card to PC using the SATA reader mentioned above but its more like 30MB/s on the firewire reader. Same SATA reader with a 30MB/s card gets me around 25MB/s. For most camera bodies that dont support UDMA the card will have little to no impact in the camera, its when you go to get the images from card to PC where the biggest impact is felt.
USB 2.0 readers have been around for years already and a decent one with a fast card is only limited by the USB 2.0 interface. Your old reader was probably limited to PIO 4.
