Photo Forum / Digital Photography / DSLR Cameras / January 2006Question about high speed flash card readers
Hi, I use CompactFlash cards and was looking for a flash card reader. It looks like just about all the brands I have seen are advertised as high speed. Is the speed really the use of USB 2.0 ? Or, is some readers actually made to be fast? Any recommendations for a CF reader? Thank you, Dave USB 2.0 is quite a bit faster than the regular (old) USB. For photos, definately get a USB 2.0. I can't imaging there is much of a price difference. (This is predicated on the assumption that your computer has a USB 2.0 port. If not, the would be no different. But a USB 2.0 card is not very expensive, either) > USB 2.0 is quite a bit faster than the regular (old) USB. For photos, > definately get a USB 2.0.

USB 2.0 "full speed" is the same speed as USB 1.X http://www.everythingusb.com/usb2/faq.htm David In article <YQ_Cf.11135$wl.3080@text.news.blueyonder.co.uk>, "David J Taylor" <david-taylor@blueyonder.co.not-this-bit.nor-this-part.uk.invalid> wrote: > But make sure it's USB 2.0 hi-speed.

Thank-you, I just did, and I am correct. There are only TWO standards, USB 1.1 and 2.0. The "buyer beware" of misleading "high speed" and "full speed" descriptions is well stated. Signature:) JR > Any recommendations for a CF reader? I bought an inexpensive ($29) Lexar CF card reader over a year ago. Today, I see the SAME thing going for less than $19 at B&H Photo. http://www.bhphotovideo.com/bnh/controller/home?O=productlist&A=details&Q=&sku= 304346&is=REG&addedTroughType=categoryNavigation Until only a week or so ago, I was using USB 1.1 - very slow. I just installed a USB 2.0 5-port PCI card in my G4 Mac tower and now this CF card reader FLYS! A short time ago, I bought a Lexar 12-in-1 USB 2.0 card reader. This allows me to get the pics from my daughter's SD card. At $29, this is another reader worth. http://www.bhphotovideo.com/bnh/controller/home?O=productlist&A=details&Q=&sku= 352044&is=REG&addedTroughType=categoryNavigation Signature:) JR USB 2.0 transfer rate is assumed to be 480mbps. In the flash card world, "1X" is 150kbps, so roughly speaking, it would take a 3200X flash card to outrun a USB 2.0 reader. I've never seen a reader claiming to be faster than another, because it essentially doesn't matter. -Steve > Hi, > [quoted text clipped - 8 lines] > Thank you, > Dave > Any recommendations for a CF reader? I've worked with quite a few brands - and haven't ever had an issue with any of them. If you're working primarily on a laptop though, you might like to consider a CF to PCMCIA adaptor - they're even cheaper, and you can leave it in the laptop all the time. > Hi, > [quoted text clipped - 8 lines] > Thank you, > Dave Lexar Firewire Compact Flash reader... 1/3 again as fast as the best USB 2 card reader. I'm a pro photographer and I use a 1Ds mk2 shooting raw and jpg.. so speed is of maximum importance to me.. a full 2 gb flash card copies to my hdd in 3 mins as compared to just over 4 mins on the usb 2 readers ( 80X Ridata Pro 2 cf card) Also remember here is no point is using a fast reader if you have slow cards...! The lexar Firewire card reader costs about 17 ukp if you shop around... Only one downside... This is not a multi type reader... CF cards only. you can get a firewire PCI card for less than a tenner, and a pcmia firewire card for a laptop for about 20 quid.. regards Andy Switching to firewire would be quicker and if you are running a MAC, you might have one. But I'm not sure I would install a firewire card just to gain the speed unless, like you, it is for very intensive work -- particularly if you have the ability to start the download and then wander around the house for 3 or 4 minutes while its downloading. On the other hand, if video is in his future then by all means he should go with firewire. > Switching to firewire would be quicker and if you are running a MAC, > you might have one.

My G4 Mac tower came with FireWire (IEEE 1394 aka FireWire 400) but its USB is the older standard, 1.1. (12mbs?) Before I paid attention, I had already purchased a Lexar CF reader (USB 2.0) and, until a week ago, used it with the 1.1 interface on my computer. It worked, albeit slowly. It is my understanding that USB 2.0 is just about as fast as FireWire 400 (IEEE 1394). Having recently installed USB 2.0 on my computer, I am experiencing several improvements in addition to how fast my camera's Sandisk Ultra II CF card downloads to the computer: Larger jobs travel to my printer noticeably faster. Printing speed even seems to have improved a bit. I expect that my Palm PDA will sync somewhat faster, if imperceptibly. I'm not sure why the peecee world was slower (still is?) to equip their stock systems with FireWire, but they were. Given there are MANY more USB 2.0 devices and peripherals out there, I guess USB 2.0 would be the preferred way to go if having to choose between that and FW. I expect that, by now, virtually all NEW USB devices and peripherals at USB 2.0-capable/compliant. Heck, when I must replace my third generation iPod (FireWire interface), I will need USB 2.0 anyway since Apple dropped the FireWire interface to iPod for the more widely available USB interface. Signature:) JR I am a PC person but I had to install a Firewire 800 on a friend's G4 because he added an external hard drive. You can't read from a camera and write to an external hard drive if they are daisy chained together. The Firewire 800 is pretty quick, but there aren't too many things that have that connection -- mostly video stuff. If you have Firewire 400, it is worth using. But I don't think the difference between that and a USB 2.0 is worth changing over to. Esp. since USB is everywhere. As for cards and stuff, yes there's a world of difference between USB 1.0 and 2.0. > It is my understanding that USB 2.0 is just about as fast as FireWire 400 > (IEEE 1394). USB 2.0 High Speed is, yes. > Having recently installed USB 2.0 on my computer, I am experiencing > several improvements in addition to how fast my camera's Sandisk > Ultra II CF card downloads to the computer: Larger jobs travel to my > printer noticeably faster.

Apple invented FireWire in the early 1990s. > Given there are MANY more USB 2.0 devices and peripherals out there, > I guess USB 2.0 would be the preferred way to go if having to choose > between that and FW. Right. Nikon didn't put a FireWire interface on the D2x for that reason.

USB2 peaks a bit higher than FW, 480mbps vs 400mbps, however USB2 cannot sustain the same data rates as FW. Probably bugger all in it in real life for downloading a compact flash card. > > Having recently installed USB 2.0 on my computer, I am experiencing > > several improvements in addition to how fast my camera's Sandisk [quoted text clipped - 7 lines] > > Apple invented FireWire in the early 1990s. And still they were quicker to universally adopt USB than the PC world too. Just a little behind with USB2 though. > > Given there are MANY more USB 2.0 devices and peripherals out there, > > I guess USB 2.0 would be the preferred way to go if having to choose > > between that and FW. > > Right. Nikon didn't put a FireWire interface on the D2x for that reason. USB2 is more common as it is simpler and cheaper, you have host devices and dumb clients, so the devices just need the cheaper dumb client device. Firewire every end is intelligent so you need the pricier chip in every device. There is other 'f.ck ups' along the way which paved the way for usb2 like Apple charging for the patent on every FW device in the early days which opened the door to usb which intel gave away for free.
