Good Afternoon! After trying all of the other tablets, Android (Nexus line, Galaxy Line), Ipad 2,3,4,Air, I decided to give the Surface pro a shot. (I purchased it refurbished from a authorized agent, it came with a 30 day no questions asked replacement.) It was love the first time I began working with it. I've only had it two weeks but the freedom of being able to do anything I want on it is a great feeling! Now that the new has worn down some I have began trying to setup everything how I want it.. I have ran into a few issues and would love some comments on if I am just too critical or if there could be something deeper. First off The SD card slot. I originally purchased a Transcend 64GB Class10 U card, (supposedly rated for 30mb/s write/80mb/s read) The card seemed to do fine, I installed a few apps to the card then it stopped working entirely. I could not erase or format the card and nothing else would write to the card. I returned it and picked up a Sandisk 64GB Class10 U card. This one seemed a bit slower but I can read and write to it. I used a program to test the read/write capabilities and I am getting only 3.5MB/s write and 35MB/s read... Seems very slow to me, I installed a game to the card and it sat at 100% usage the entire time with a max write of 3.5MB/s downloading Games from Steam to the card is terrible as well, it causes the download to peak, then drop to nothing while it writes to the card... Its almost unbearable... I'll put the card in my Macbook Pro's SD slot tonight and test it there to see if its any faster. Just curious if anyone else is getting slow read/write on the pro Secondly the battery life! UGH! I made a custom power plan, changed all the settings to low , set the display at 15%, cpu throttling to 20% max cpu on battery, set every other option recommend to extend battery life. At 100-99% charged the power meter says it will last 2 hours an 50 minutes. A friend at work has one and he said he can get 6 hours or so out of his surface pro with similar settings, this seems like a huge difference to me, Do you all normally get life like his ? I am wondering if it may be worth a shot swapping this for another one, Or getting a refund and putting that towards the Pro2.... other than the SD card woes and the low battery life the thing works great I'd hate to trade two issues like that for possibly some other issues. Any idea's would be great! Thanks!
