Twelve inches deep, four bays each, and together they won’t go offline. This is a pair of QNAP TS-h765eU short-depth NAS units in the lab, with 30TB Seagate IronWolf Pro drives, 120TB raw per box. Around back, E1.S NVMe bays handle cache or flash volumes. QNAP’s HA Manager turns them into a failover cluster: we pulled the power on one mid-transfer and the copy resumed 50 seconds later without dropping a file. Full review and video at the link in bio. #QNAP #NAS #HighAvailability
