| 1430364 | 2017-01-01 03:46:00 | The title above gives a lot of the picture. Our desktop, which is Windows 10, has USB3, which I am using. Put my SD Card from my camera in, with 290 images taken today. The desktop did not recognise the SD Card (ie did not "see" it), so I put the intermediary of a card reader in-between and all was fine, seemingly. Now my desktop is saying that it will take 1hr 25 mins to transfer from the SD Card to the desktop. Now, I know full well that these times can vary wildly, however on waiting it still is on track to be that long. Does this mean that my card reader and SD Cards (many) need to be upgraded to USB3 to obtain much quicker transfer rates?? | Misty (368) | ||
| 1430365 | 2017-01-01 04:01:00 | The card reader will need to be USB 3 if you want USB 3 speed transfers. Otherwise it will revert to USB 2 speed. | CliveM (6007) | ||
| 1430366 | 2017-01-01 04:11:00 | Thanks Clive, that solves part of the problem, but what about the SD Card(s)? | Misty (368) | ||
| 1430367 | 2017-01-01 04:26:00 | How it all works is the transfer rate will only be as fast as the Slowest Device is capable. Meaning if the Card Reader is capable of USB 3 speeds, but the cards or other usb devices are only USB 2 speeds, then USB 2 is the fastest it can go. Different Cards / USB devices also have different Speeds. ANY speed ratings are theoretical speeds, because in reality its often different, usually slower. |

| 1430368 | 2017-01-01 04:40:00 | The desktop did not recognise the SD Card (ie did not "see" it) Try uninstalling the Card Reader on your Desktop in Device manager and do a restart to get it to read the Card Had to do this a couple of times with various Windows 10 builds to get my internal card reader to work |

| 1430369 | 2017-01-01 04:58:00 | Thanks wainuitech, just managed to get something similar from the web. SD Cards are 2,4,6,8,10 Mgs a second roughly speaking. This is a Sandisk from the bargain bin at PBTech which has a rating of 1 (only) which explains why is is tranferring at the rate of just under, and just over, I mgs a second (plus a slow card reader). I have not gone to sleep yet, but will be using my other cards of 4 and 6, which have been substantially quicker. Will also buy a much, much quicker SanDisk card. Will have to watch those PBTech bargain bins, which may well suit your average photographer ! :-( | Misty (368) | ||
| 1430370 | 2017-01-01 05:13:00 | Came across the following site, may be of interest, gives some good comparisons. http://www.cameramemoryspeed.com/ Will have to watch those PBTech bargain bins Yeah, sometimes not always a good bargain in the long run. I personally work on the terms if you want something of good quality and performance be prepared to pay a little extra for it. |

| 1430371 | 2017-01-01 21:34:00 | Even class 10 cards are not particularly fast compared to a decent USB 3 flash drive or even old school external hard drive, some expensive ones are getting there though. I find the best card reader for cameras is often the camera itself, if it has a cable connect it directly to the PC and try that. It seems the PC has a card reader of some kind built in and that didn't read the card? not all card readers support all SD cards, there are different standards and speeds. Also just because your PC has USB 3 that doesn't mean the card reader that's included is connected to a USB 3 port internally, and not all external USB ports are necessarily USB 3 either, most PCs have a mixture of USB 2 & 3 and you can usually tell by colour - USB 3 is usually blue (but not always) and USB 2 is usually black |

| 1430372 | 2017-01-03 20:39:00 | Not sure if you used/mentioned a mini USB stick card reader. I have the strontium mini USB 32 GB SD card reader (about 28 dollars) bit pricey from JB Wifi, More so I think for the U3 Nitro version. (www.tech2cool.com). If JB has it in stock. So should work effectively - a mini U3 USB card reader connected to U3 USB port. I got tired of messing around with several lower GB SD cards, and the inbuilt SD reader... | kahawai chaser (3545) | ||
| 1430373 | 2017-01-04 21:04:00 | Now my desktop is saying that it will take 1hr 25 mins to transfer from the SD Card to the desktop. If you're card reader is actually USB2, then the cards are to blame. I can copy a full 16GB SDHC card to my PC in about 15-20mins. There are many (confusing) speed standards for cards and generally speaking, the cheaper they are the worse the read & write performance will be. |
