Hi, I thought the forum might be interested to know that I had success running a Toshiba 128 GB mSATA SSD in my iRiver H340. I slipped the SSD onto an adapter card and then fitted the adapter card with a ZIF to IDE 50 pin adapter and inserted it in to the player where the hard drive used to be. The original firmware doesn't recognise the drive at all but the USB can be used and I was able to allocate the drive, name it, and format to FAT32. I then loaded up the latest version of Rockbox and it came up flawlessly. So far the unit seems to be very light on battery power as well as being much lighter. I have my eye on the Mushkin Atlas 480 GB mSATA SSD.
