    So slow T61p's internal card reader

    I'm using T61p with RICHO built-in 4-in card reader. I've just purchased SanDisk 4GB Ultra II 4.0GB Memory Stick PRO Duo, and shocked its so slow speed!

    My desktop's reader showed around 10MB/s with this card. However, built-in reader only gives 3MB/s. Worse, CPU usage was around 50% :mad: while other r/w (including hdd and flash cards) shows less than 7~8%. Looks like very old programmed I/O. See the attaced capture.

    Overall r/w performance was extremely poorer than even a cheap and older card reader with CF.

    I guess this is a fault of RICOH card reader driver. Or, MS Duo isn't that good with my T61p? I don't have a SD card yet, so don't know about whether SD card would suffer this problem as well.

    p.s. I'm using Vista Ultimate 32-bit version now.

    My Lenovo 3000 N200 also has a built-in Ricoh multi card reader and I have exactly the same problem. I tested a Lexar professional 133x 4GB SDHC card and an old Kingston 512mb SD card, both show the same slow 4mb/s read speed in HD Tune and CPU usage at above 50%. When I use an external USB 2.0 card reader, the speed is much better: The lexar reads at 20mb/s and Kingston at 7mb/s, and CPU usage is minimal. I tried driver update but Vista (32bit business) says I already have the latest driver.

    It totally defeats the purpose of having a internal card reader if you have to carry around an external USB reader.

    Unless you hate carrying around external stuff, the benefit outweighs the cons for me.

    Just thought I'd add that a Transcend Class 6 SDHC card I just purchased has a (large file) write speed of around 11MB/s under Vista 32bit using the T61p cardreader - a lot faster than the 6MB/s I was expecting (class 6).

    I also have a Sandisk Ultra II MiniSD card which could perform the same test at 5-6MB/s or thereabouts (it's rated at 9MB/s write).

    I still have the same problem using an Asus A8JS.
    I tested 6 different drivers to no avail.

    Same issue, an external reader manages 5x the speed of the internal Ricoh one.

    I've got same problem with my HP Pavilion dv9700t with a RICOH card reader. Reader is very slow, when I transfer files, or view photos or watch videos off a memory card the computer really slows down and the sound becomes abrupt. When I play videos off a memory card they stop frequently.

    Is there any solution for it? Maybe some alternative drivers? Or is it a hardware design flaw?

    TIA
