NAS Units

QNAP NAS units, two-bay desktop through short-depth rackmount, including the fanless and 2.5 GbE models. Drives sold separately — see NAS drives.
QNAP generally gives you more ports and bays for the money; Synology gives you better software. Choosing a NAS compares them. Measure internal rack depth before ordering a rackmount unit — it is the commonest reason one goes back.
