I’ve replaced the hard disk that shipped with by NB10 with an SSD.
As well as as being faster, this also makes the machine totally silent in-use, as it’s fanless.
There were a couple of quirks which are worth noting.
1: The Toshiba BIOS would not detect the new disk until it had been completely powered-down, which requires that the battery be removed.
Toshiba do note in their official instructions (at http://aps2.toshiba-tro.de/kb0/CRU3C03K80000R01.htm and http://www.youtube.com/watch?v=NNheio21qR0) that this is necessary – but as the battery must be unscrewed for removal, it’s perhaps not obvious.
2: The boot order doesn’t appear to be respected. I’m not 100% sure what the cause of this is, but although the SSD is set to be the first boot device, the system always starts by trying to read a USB device and then PXE boot, before trying the SSD.
