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?

Thank you,

James Campbell

OK, maybe it is just that reader, new HP laptop also built in reader, reading at 40 - 87mb/sec and writing arfound 67 mb/sec so exceeding advertised reading

:smiley:   Hi James,

_ Dear member of SanDisk Community, welcome. _

Ok! Congratulations, by the clarity of the message, and the way to solve the problem.
As you say, then, is the internal card-reader from Lenovo.
Therefore, upgrading only the driver of the card-reader, and see what happens.

Enjoy, and then you tell us, what happened, please.

Regards, Alfred.                                                              (Google translated)
