14TB SAS hard drive
This 14TB SAS hard drive uses a 12Gb/s interface and spins at 7200 RPM. It is built for surveillance networks and other always-on workloads that exceed typical desktop duty cycles. The 3.5 inch form factor fits standard drive bays in servers and network video recorders.
Sustained 24/7 operation
The drive is engineered for continuous operation rather than short bursts, withstanding elevated heat and vibration inside NVR enclosures. A 512MB cache helps smooth heavy write streams from multiple high-definition cameras. It targets environments where drives run 24 hours a day, seven days a week.
SAS 12Gb/s interface limits
The SAS 12Gb/s link sets the maximum host transfer rate for this drive. Actual throughput will vary with system topology, cable length and controller capabilities. Buyers who need a different interface or higher single-drive bandwidth should consider other storage architectures.

Questions about this item
How much power does the 14TB SAS 12Gb/s 7200RPM drive draw during continuous 24/7 operation?
The drive is engineered for always-on surveillance workloads and handles elevated heat fluctuations in NVR environments without the short-interval limits of average desktop drives.
What host interface and backplane does the WUH721414AL5204 require to operate?
It needs a SAS 12Gb/s host bus adapter or RAID controller and a 3.5-inch drive bay with SAS power and data connectors.
Can the 14TB SAS 12Gb/s drive share a backplane with older 6Gb/s SAS drives?
Yes, the SAS 12Gb/s interface negotiates down to 6Gb/s so it will work alongside legacy SAS drives on the same backplane.
