    Sony Laptop (fw290) SD/MMC built-in reader slow

    I have Sony VGN-FW290 laptop. While performing bench mark, I noticed that the built in SD/MMC reader/writer read speed is very slow.

    SD cards read at 2-2.5MB/s and MS Pro Duo cards read 6 MB/s. When I use my external USB flash reader ($10 Link Depot multi-card reader), I get 10-17MB/s for SD and 15MB/s for MS Pro Duo.

    I am up to date on driver for the SD/MMC slot (looks to be made by Ricoh).

    Anyone else noticing the same problem with the built-in flash readers?

    Thanks

    The FW290 has Ricoh R5C822 SD/MMC reader. Sony support says that the speed is due to hardware limitation and that is the maximum speed.

    I have another Sony laptop and that one maxes out at ~7MB/s for both SD/MMC card. It has different hardware component for the reader.

    Both laptops are less than 2 years old.
