What is the speed of the SD reader? Transfer speed is an issue when using 64GB and 128GB videos and images.

64Gb and 128Gb cards are technically XC, not SD. The specs say that it is compatible with XC, so presumably it has the extra contacts and the required support firmware to do that, however it might be wise to read some of the 1- and 2-star reviews before buying.

This thing is very fast never had a read issue. I think it would be more dependent on the speed class of the SD card. The USB speed on this thing blows my mind!

I've found that ALL "SD" cards will work. SD is a standard for the card size and performance. Even though all SD cards are the same size and will fit and function in any device with an SD reader, the performance can vary. I use the medium to high grade (fast) ones for the best performance. If you are going to shoot HD video you really should use the higher grade SD's as they are faster and will give you a higher quality final image. Research it some more by "Googleing" SD standards to learn more about SD standards of performance. You can usually find the higher grade ones on sale somewhere, just make sure the speed is adequate for your needs. Good luck! I've found that ALL "SD" cards will work.

Yes. I've used it in multiple readers with no problem. It essentially is a CF card with removable storage. Make sure it is a Type II reader as a type I card is slightly thinner. Your transfer speeds will be limited to the max speed of the actual SD card.

I have had no problems with this memory card, as far as download speeds. it has done its job very well, to determine that you also have to factor in network connection. The read speed is the up to 40.

I guess it not means the size of the HD, but it has a limit size of transfer, if the file is 200gbs it cant be transfer, the max size of the files that can be transfer is 160 gb, no metter if the HD is 4 Tb. You can transfer all files u want but the files cant be bigger that 160 gb.so le read again: [it will transfer files] "Up to 480 Mbps data transfer rates,[but those files that can be transfer at that speed had a size limit:] 160GB capacity max" Thats is what I understand.

I've had no problems at all with the USB. Transfer time are longer because the images (and especially high speed video) themselves are larger. You do have to press the power button after plugging it in to activate. It charges through the USB port. I did have one SD card go bad, but the SAN Disk Extreme Plus 80MB/s is holding up well.

Yes. I have a Sandisk Extreme Pro 128GB UDMA7 card rated at 160MB/s. On this reader, I'm getting a whopping 50MB/s. junk.

It is somewhat slow. I have not tested with an HDD but it seems that transferring a 1 GB from an SD card to a USB flash drive took a little longer than 10 mins for me. It might depend on the speed of the SD card and the HDD. When I connected the SD card and the USB flash drive directly to the computer the same file transfer took about 4-5 mins. So I would say that there is a factor of 2-3 drop in speed when using this device. I used the FtpMate app on my iPad to do the transfer.

I'm using the Samsung pro xc1. It has ver fast read and write speeds. I figured if I'm spending that much on a player why skimp on the card. I have been very happy with this card. It is the 64G

Depends on the file system you use, out of the box it can transfer files upto ~64GB

Hello Alex, Even with slower class 4 SD card still generated fast enough transfer rate (read/write) to play back a HD video. The one I used is SanDisk ultra 64GB class 10 I bought it from amazon, it work just fine. I have noted that way back when I downloaded more than a dozen of free apps from google play store based on rating and testing them to see which one work best and found out that many media (video) player program are in premature development stage, their playback are sluggish and freezing all the time, few others are just ok because they are too simple and lacks of features, but the only one I am interested is the MX player, my search ended and this MX player is the only one I using today on my Samsung s3 cellphone and my new Samsung tab 3 I just bought from amazon. regardless HD or SD the playback is flawlessly with this MX player. I think before you spend more money for faster SD card may be you should download and try this MX player to see if the poor video playback problem solved if not then switch to faster class10 SD memory card. Remember after you download and open the player for the first time, it may prompt to download CODE for the MX player to work properly. Once the player open, select a file you want to play them then go-to setting by select tool/setting/decoder and place check marks on all those check box that uses H/W+ decoder, then you are done and all of your video now should playback smoothly. By the way I had been using this MX player for the past 2 plus years until today. I hope this help and good luck!

This is a somewhat inconclusive Answer: I no longer have the original packaging. The 64 GB does not state speed on the actual drive & I am on USB 2. I do have a 32gb from the same series & it does state USB 3.0 on the drive.

I have this: 30 MB/S is printed on it, pretty fast. Purchased a SanDisk Extreme 80 MB/s for my new 70D also, but cannot sense the speed difference of the two cards in the camera.

I use the SanDisk Ultra Plus 64GB. Micro SD card UHS-1 Card with Adapter. This card gives you faster transfer speeds. The cards can be found at either Amazon or RadioShack.
