card reader

[Cebu_Boy]

i also ask this question in "media & storage" forum. but nobody can give me straight answer. hopefully i have luck here. here is the situation. i bought a "high speed" USB 2.0 card reader hoping i can transfer my files from my MS pro to my laptop much faster than my previous card reader which is USB 1.1. so far im kinda disappointed. i cant see any difference in speed. i tried both card readers to my laptop and my desktop and they are still the same. any suggestions? i use xp for both of my computers. thanks.

Are your laptop / desktop USB ports USB2.0? If you are seeing no change, they are probably just USB1. .1

You can get a USB2.0 card anywhere online for pretty cheap, less than $20 shipped.

i just got my laptop few days ago and im 100% sure it has 2.0. unless the laptop manufacturer lied about their specs.

If you are transferring 1 at a time, you won't notice any difference. Even if you are transferring several, there are other factors.

1. Laptop speeds are affected by disk speeds and the amount of memory you have available. Laptop disks are much slower than the ones in desktops to conserve power. Memory is usually less too for the same reason. Sometimes the adjacent overhead is a big part of the equation.

2. Most laptops are not optimized for large file transfers. Are you using "drag & drop" or a transfer program. Transfer programs can be slower since they may not be optimized for transfer speed.

3. My MSPro Sandisk USB 2.0 card reader is $20 at Circuit City and the old 1.1 readers were selling about the same price.

Good luck

i think this is not the problem. and im pretty sure i have enough memory (512mb) in my laptop. and during transferring i didnt open any application.

2. Most laptops are not optimized for large file transfers. Are you
using "drag & drop" or a transfer program. Transfer programs can be
slower since they may not be optimized for transfer speed.

i used xp drag & drop. not any transfer program. i downloaded a full 256mb MS sandisk pro. so i think it was a pretty good size to test.

3. My MSPro Sandisk USB 2.0 card reader is $20 at Circuit City
and the old 1.1 readers were selling about the same price.

do you think it will make any difference if i buy sandisk brand card reader?

thanks again for replying.

The hard drive speed on your notebook is probably 4200 rpms. Unless you're transferring a ton of pictures at the same time you won't see that big a difference between the old and new reader.

The difference in throughput between USB 1.1 and 2.0 is minimal. Your media might be slow and maxxed out on either interface, in which case you'll never "see" a difference.

If you are expecting to have your socks blown off by the blazing speed of USB, it isn't going to happen. USB is a slow interface relatively speaking. It is measured in mega bits per second not mega bytes per second.

Good luck on getting the answer your looking for. By the way "high speed" doesn't mean high speed all the time. It's a term abused by marketing for the best possible speed attainable for a certain class of devices, and has been around since USB 1.0. It's part of the spec.

i think you and the person before you answer my question. at least i know there nothing wrong with my card reader and my laptop. and to answer the other person. yes my HD is 4200. so i think it also of my HD.

how fast (how many seconds per file) does your USB 2.0 download a picture file (1.2MB ave. file) assuming your using MS pro and your PC has USB 2.0 port. just want to get and idea from the realworld how fast does USB2.0 work. thanks again.

 

[widebrush]

A 1.2MB file would be as soon as I release the mouse on a drag and drop. Bascially, instantaneously. But that doesn't scale with multiple files as there is a ton of file system overhead associated with muti file transfers.

Try some research here to get the facts about USB:

http://www.usb.org/home

Laptops are definately slower on some (maybe all) things when compared to an equivalent desktop. This is particularly true for the P4 class laptop machines. Most of the OEMs throttle the CPU back to half speed to reduce heat in the cramped space inside a laptop. This would cause some functions to be slower. I/O could be one of them. The Centrino is a different story. Centrino class CPUs can be run full speed, since they are low-power low heat. A P4 can be run at full speed too, but it usually is not the case.

By the way, it's not your hard drive in and of itself. A hard disk is magnitudes faster than USB. Even old hard drives

If you are seeing transfers that are rediculously slow, you have an issue that should be addressed where you purchased the laptop or card reader. If your hardware is not messed up, it sounds like a driver issue. I believe XP has USB driver issues related to USB 2.0. You've heard of Windows Update? If not look into it.

Regardless, it surely won't get fixed here. ;-)

My Sandisk 2.0 card reader into a USB 2.0 port takes about 2 seconds for a 3.4 MB 8MP JPEG from my 828. That is a drag & drop of 25 photos.
System
3.4 MHz Pentium 4 with 800 Mb front side buss.
2 GB RAM
120 + 250 GHz HDD with 7800 rpm and 8Mb buffer
1280x1024 32bpp LCD 19" monitor

So the system is fast, as of 1 month ago, it was as fast as I could design it.
I think I got the B and b in the right places.

Note that some vendors market a Full Speed USB 2.0 and that is not the same as High Speed. In either case, the 2.0 interface is much more stable than the 1.1.

Mostly I would start the transfer process, go make a cup of coffee, and by the time I got back to the computer the transfer was complete. So speed is realtive.
Good Luck
Mel

2.66 GHz Pentium 4 tower; 1 GB RAM; 7200 rpm Maxtor ATA 133. Tested with a set of 21 Canon RAW files totalling 128.7 MB on a Transcend 256 MB CF card, transferred by drag-and-drop:

USB 1.1 card reader: 2 mins 13 seconds
USB 2.0 card reader: 56 seconds

I find it hard to credit that some claim negligible difference in throughput. There's no reason for me to suspect the old 1.1 card reader, either. I get a similar order of difference with my partner's EX-Z3 (1.1) connected directly via its cradle versus its SD card in the same 2.0 reader. And it's a cheap no-name multi-format reader. A little cantankerous on occasions, but when things are working correctly it seems more than acceptably fast.

I'm not versed in notebook issues so I wouldn't know what to expect from the current state of the art.
