I have seen a similar issue when transferring to micro SD cards,
transfer seems to plateau out at between 300-500kB/s. Especially
prevalent with large sustained transfers.
I assumed it was the flash cards because it didn't matter if I used
the laptops built in card reader or a usb trans-flash adapter, Now I'm
starting to think it's an inherent problem with flash memory
24x7x365 != 24x7x52 Stupid or bad maths?
<erno> hm. I've lost a machine.. literally _lost_. it responds to
ping, it works completely, I just can't figure out where in my
apartment it is.
