Swift suggests smoothness and sureness of movement (a swift current), and fleet, lightness of movement (The cheetah is the fleetest of animals). Speedy refers to velocity (a speedy train) or to promptness or hurry (a speedy resolution to the problem). Quick most often applies to what takes little time or to what is prompt: a quick snack; your quick reaction.
Hasty implies hurried action (a hasty visit) and often a lack of care or thought (regretted the hasty decision). Expeditious suggests rapid efficiency: sent the package by the most expeditious means. See Also Synonyms at faithful.

Word Origin & History

fast  (adj.)
O.E. fæst "firmly fixed, steadfast," probably from P.Gmc. *fastuz (cf. O.N. fastr, Du. vast, Ger. fest), from PIE base *past- "firm" (cf. Skt. pastyam "dwelling place"). The adv. meaning "quickly, swiftly" was perhaps in O.E., or from O.N. fast, either way developing from the sense of "firmly, strongly, vigorously" (cf. to run hard means to run fast; also compare fast asleep), or perhaps from the notion of a runner who "sticks" close to whatever he is chasing. The sense of "living an unrestrained life" (usually of women) is from 1746; fast food is first attested 1951. Fast-forward first recorded 1948. Fast and loose is described as "a cheating game played with a stick and a belt or string, so arranged that a spectator would think he could make the latter fast by placing a stick through its intricate folds, whereas the operator could detach it at once." [James O. Halliwell, "Dictionary of Archaic and Provincial Words," 1847]. The fig. sense (1557) is recorded earlier than the literal (1578).
