Higher SD/CF card read/write speeds than the reader/writer .. any benefit?
I've noticed some pretty fast CF/SD cards these days.. as high as
22.2MB/s on reads and writes.. compared to my 10 MB/s SD or 4.8 MB/s CF card.. I dont have or can find the exact specs on my memory card reader.. but lets say its 10 MB/s, would there really be any benefit to having a faster card (I would think not).. Same thing on the camera side.. Again, I'm not sure what the write speeds are on my Fuji s602Zoom.. Anyone have any thoughts.. Again, I would think having faster cards than the read/writes are capable would prove useless.. Thanks |

Beard- Hide quoted text - - Show quoted text - Yeah this is true.. I guess the usb 2.0 speeds would be defeating the purpose. I guess my original question was more focused on the devices that use the cards, more so than the seperate readers.. IE: the camera, the pocketpc.. I would think that the memory comparison would apply moreso here, than (not at all) with the last comparison (imo). Good call though.. but i can say.. my 60 or 70x SD card, when put in my USB 2.0 reader.. gets about 10.6 MB/s (about what its rated at) on the read speeds.. obviously given the fact that the reader is 2.0, if i threw a 150x card in there, i'm sure it would spit out 22.2 MB/s.. Now if I put a 150x card in a camera that only could read as fast as say 70x, I guess first off, it may not even read it, but say it did (acting like a CDR or DVDR with a range of speeds that it, the memory card, could write/read at), then if it acts like a writable disk.. it would probably only use its maximum value on the read/write, defeating the purpose of having a faster memory card in a device that has a limit on this (my idea anyway).. |

Yes, the card, camera, reader, computer 'system' is limited to the slowest device in the current chain. The 480 mbps spec for USB 2.0 is merely theoretical. Real world figures come nowhere close to that speed. I believe the fastest cards can do about 9 meg/second (that's bytes), which seems to be as fast as my 100mbps ethernet adapter will transfer data between my computers, and will still take a couple of minutes to copy a 1GB card to the computer, IF the reader/camera, is fast enough for the card to go full speed. If you have only a USB 1.1 reader, go to lunch. |

Super-high speed cards are not going to help take pictures any faster than moderate speed cards (well, except *perhaps* with the new Canon 1D Mark III at 10 fps & dual Digic processors) - they just help decrease the download time from the card. I've got lots of time, I don't need to spend lots more $$$# to dump my cards that fast. -- You need only reflect that one of the best ways to get yourself a reputation as a dangerous citizen these days is to go about repeating the very phrases which our founding fathers used in the struggle for independence. -- Charles A.
