Ultrastar DC HC550 is Western Digital's helium-filled 16 TB CMR data-centre drive: 256 MB cache, dual-port SAS 12 Gb/s, 3.5-inch, rated for the always-on workloads a spinning platform still does well — bulk, cold and warm tiers, video capture, and long-lived archives.
Both units photographed on this page carry an additional NetApp spare-part sticker — NetApp MTG part numbers X388A and X387A — so they can be matched against a NetApp BOM as well as against the Western Digital part number.
The photographs on this page are of the physical units held in our Guangzhou warehouse — the labels shown are the units' own labels, not a catalogue rendering.
They ship with those original labels intact. Power-on hours and SMART health are recorded per unit and disclosed before you commit to an order.
