Just bought Sandisk Extreme Plus microSDHC UHS-I Card 32 GB. Says speeds up to 80MB/sec. I am lucky if I see 30mb/sec and that is peak, right now it is transferring at 6mb/sec, that is on my laptop. I will try other devices and update, but this seems a bit slow. I am using the adaptor it came with, with the built in reader on a Lenovo Laptop. Now up to 17 MB/sec in Windows 8.1. Is there anything I can do to get even close to the advertised speeds?
