Review on Kingston Digital Memory SD10V 8GB by Brad Ward

First I bought the card because I have an HD camera that I wanted to capture more minutes of video from . The only compatible cards listed have a maximum capacity of 32GB. So I bought this hoping it would work in camera. It's not like this. The camera gave me an SD card error every time I turned it on with it. My existing 32GB card is fine. Maybe it's the camera not accepting SD cards larger than 32GB which they didn't think of. Then I thought I could use this in my laptop's SD slot. It's nice to have an extra "hard drive" without a cable or USB stick sticking out. So I plugged it in and copied some of my important files to it. I tried to transfer 5,584,041,865 bytes in 2094 files and 66 folders there. It copied well until about halfway through. I keep getting a Win7 semaphore timeout error. I ended up having to abort the copy process, basically telling it to "ignore" all occurrences of the same error. I've looked into the "semaphore" error a bit. There seem to be two things causing this error: (1) network issues and (2) NTFS is not being used. I don't understand how transferring files from one drive on my computer to another drive on my computer can affect a network. So I decided to reformat the SD card which apparently came from exFAT to NTFS. I was then able to copy these 5g files to the hard drive. It took a long time and I didn't have time. But when I started working with apps on some files on the drive, they were REALLY slow. Unacceptably slow. Perhaps that SD card, useless for a camera and useless as a scratch disk, could just act as a long-term emergency backup. I then set up some tests to make more copies to the SD card. First, I completely disabled networking on my laptop - disabled everything. Then I plugged the SD card into the USB adapter. Tried two instances as tests. The first copy weighed about 771 MB and was an ISO image of the operating system installation disk. I then copied over 2.1g of the Adobe Acrobat X installation files. They came over fine. It seemed to take a long time but I timed it out and both were around 8-9 MB/s. Then I put the SD card in the SD slot. The ISO image was copied around the same time, so the speed was about the same. Adobe copy didn't work. He gave the file's second name and indicated that he was calculating the time - and that was all he did. I went for lunch and came back and it was still in the same place. I went to get some stuff done on my phone and gave it more time and it was the same. I clicked the cancel box and it got stuck. I didn't stop it until I did a hard shutdown. The SD card slot in my laptop is connected to the device manager and not to the USB bus. I almost never use the SD slot; Maybe that really is the culprit here, but I can't tell. So I can't find any use for this SD card. I've tried three use cases and it can't run any of them reliably. I destroyed the packaging when opening it, so I cannot return it. I can't verify that I can remove my personal information from the card, so it's most likely a one-time backup of this 5G. I could do it with DVD-R.
