The WD Ultrastar DC HC580 0F62785 is a 22TB SATA hard drive for servers and storage arrays that run around the clock. WD's model number for it is WUH722422ALE6L4. One drive, two numbers.
It spins at 7200 RPM and carries a 512MB cache. CMR recording keeps rewrites steady, which SMR drives can't promise. Ten platters sit in a helium-filled case. OptiNAND flash backs ArmorCache, which saves cached data if power drops without warning.
WD aims this enterprise hard drive at cloud storage, scale-out data centers, and hyperconverged servers. Distributed file systems and Hadoop analytics are on its list too. Twelve bays of 22TB drives add up to 264TB of raw space.
Idle draw is 5.5 W, so sixty drives idle near 330 W. Noise runs 2.0 bels at idle and 3.2 while working. Keep air moving across the 5 to 60°C operating range.
The 512e format shows 512-byte sectors to the host and uses 4K sectors inside. Modern controllers handle that fine.

Yes. WUH722422ALE6L4 is the model number. 0F62785 is WD's part number for that same drive.
It means no hardware encryption. The drive still supports ATA Security and overwrite-based Sanitize. The self-encrypting version is WUH722422ALE6L1, part number 0F62784.
Both are 22TB, 7200 RPM CMR drives with a 512MB cache and a 550TB yearly workload rating. The HC580 draws a bit less on SATA: 5.5 W idle against 5.7 W. It also uses energy-assisted recording, while the HC570 uses ePMR.
At the top speed of 291 MB/s, one pass over 22TB takes about 21 hours. Real rebuilds run longer.
Yes, if the NAS accepts third-party SATA drives. Check the maker's drive list first. Enterprise drives run louder than most NAS drives.
