Does one exist?
I've always known them as thumbdrives but after doing a search it turns out that ThumbDrive is the name for the specific brand that was marketed here in Singapore, and not the general term. I'm not sure about its international usage.
If I do a search for 'USB flash drive', I get entries referring to it as that, and if I do a search for 'thumbdrive' I get pages of people referring to it as a thumbdrive, and apparently it also goes by the brandname 'DiskOnKey' in some places; there are a lot of variants, and I was wondering if there was a more generic one.
Story context: American character uses a USB flash drive and he refers to it (e.g. "pass me that _____."). I'm just curious what term he would be likely to use.
