p.s. after I installed the app I did gain about 1Mbps of throughput.
Any idea why my SD is slow, or how to improve external SD R/W speeds? I found one app, "SD Speed Increase" that changes somethings in the system to help increase speeds, I also found out how and what file it changes, and verified it actually did make that change, but still my speeds are pretty poor. I have a ScanDisk 32gig, UHS-1 card. Any ideas?
